Reupload of a previously uploaded film with improved video & sound. Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ from http://en.wikipedia.org/wiki/Star A star is a massive, luminous ball of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible from Earth during the night, most commonly appearing as a multitude of fixed luminous points, when they are not outshone by the Sun or blocked by atmospheric phenomena. Historically, the most prominent stars on the celestial sphere were grouped together into constellations and asterisms, and the brightest stars gained proper names. Extensive catalogues of stars have been assembled by astronomers, which provide standardized star designations. For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen in its core releasing energy that traverses the star's interior and then radiates into outer space. Almost all naturally occurring elements heavier than helium were created by stars, either via stellar nucleosynthesis during their lifetimes or by supernova nucleosynthesis when stars explode. Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate... A star begins as a collapsing cloud of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Once the stellar core is sufficiently dense, some of the hydrogen is steadily converted into helium through the process of nuclear fusion. The remainder of the star's interior carries energy away from the core through a combination of radiative and convective processes. The star's internal pressure prevents it from collapsing further under its own gravity. Once the hydrogen fuel at the core is exhausted, those stars having at least 0.4 times the mass of the Sun expand to become a red giant, in some cases fusing heavier elements at the core or in shells around the core. The star then evolves into a degenerate form, recycling a portion of the matter into the interstellar environment, where it will form a new generation of stars with a higher proportion of heavy elements... Stars spend about 90% of their lifetime fusing hydrogen to produce helium in high-temperature and high-pressure reactions near the core. Such stars are said to be on the main sequence and are called dwarf stars. Starting at zero-age main sequence, the proportion of helium in a star's core will steadily increase. As a consequence, in order to maintain the required rate of nuclear fusion at the core, the star will slowly increase in temperature and luminosity--the Sun, for example, is estimated to have increased in luminosity by about 40% since it reached the main sequence 4.6 billion years ago. Every star generates a stellar wind of particles that causes a continual outflow of gas into space. For most stars, the amount of mass lost is negligible. The Sun loses 10−14 solar masses every year, or about 0.01% of its total mass over its entire lifespan. However very massive stars can lose 10−7 to 10−5 solar masses each year, significantly affecting their evolution. Stars that begin with more than 50 solar masses can lose over half their total mass while they remain on the main sequence. The duration that a star spends on the main sequence depends primarily on the amount of fuel it has to fuse and the rate at which it fuses that fuel, i.e. its initial mass and its luminosity. For the Sun, this is estimated to be about 1010 years. Large stars consume their fuel very rapidly and are short-lived. Small stars (called red dwarfs) consume their fuel very slowly and last tens to hundreds of billions of years. At the end of their lives, they simply become dimmer and dimmer. However, since the lifespan of such stars is greater than the current age of the universe (13.7 billion years), no red dwarfs are expected to have yet reached this state.

the easy way to measure the distance between stars
 
02:09
How is it possible astronomers know distances in the universe where they can't arrive at all? In this workshop participants will get an insight into the parallax method, that laid the basis for the measurement of the universe. This method is based on the triangulation method that is used on the earth. We will start outdoor: participants will measure by triangulation the distance to an object they can't reach. They will use simple instruments made by themselves. No calculations are necessary, the distances can be found by a geometrical method. Building on this method and measurement, we develop insight into the parallax method. We will see how it has been applied to find basic distances in the sky, from the moon until the nearby stars. This series of activities will help you to understand how distances in the universe can be measured by the parallax method. This method, like several other methods to determine distances, is based on the principle that a triangle is completely known with only three elements. Therefore those methods are called triangulation methods. They are used by surveyors to make a map of a region. To understand those methods it is not necessary to make calculations or to know about trigonometry. We have only to measure angles and the length of a basis line that is within our reach, then we make a scale drawing. So we need two instruments for measuring (an angle-measure tool and a tape measure) and a ruler, a protractor, paper and pencil for drawing, that's all! We will start with an outdoor activity, measuring the distance to an object (tree, house) without arriving there, like surveyors do. It will become clear that practically there are some problems in using the same method for objects in the sky. Thus, another method is proposed to determine a triangle, using the phenomenon of parallax. Also this method we will use first in our own environment. Then it will be shown how it was used to determine the distance to the moon, some planets and nearby stars. Determining a distance by triangulation You need an angle-measuring tool (the professional one is called theodolite and is used by surveyors), one or two sticks, about as high as yourself and a tape measure. Here's how we might measure the distance of a tree, like in the situation that is sketched above. Imagine you can walk from A until B, but you can't reach the tree, for instance, because there is a river between you and the tree. The trick is that you determine the shape and the dimensions of the triangle ABC. When you measure AB (the baseline) and the two angles a (BAC) and b (ABC), the triangle ABC is completely known. As you may see, when the tree is farther away (C'), the angle at C becomes smaller and the shape of the triangle becomes different. Determining a real distance by triangulation. Mark two places, A and B, for instance by standing vertical sticks on the ground. The points A and B, together with the tree at point C, form a triangle. Measure the distance AB with the tape measure. Stand at point A and measure BAC using an angle-measuring tool by looking at the tree and at the stick in B. Then move to the point B and measure ABC. So you know the length of one side of the triangle - our baseline - plus the angles at which the other sides branch off from it. Construct on paper the triangle ABC on the scale. Using your ruler and the scale, you can simple calculate the distance from every point of your baseline to the tree.

Celestial navigation uses "sights," or angular measurements taken between a celestial body (the sun, the moon, a planet or a star) and the visible horizon. The sun is most commonly used, but navigators can also use the moon, a planet, Polaris, or one of 57 other navigational stars whose coordinates are tabulated in the nautical almanac and air almanacs. Celestial navigation is the use of angular measurements (sights) between celestial bodies and the visible horizon to locate one's position on the globe, on land as well as at sea. At a given time, any celestial body is located directly over one point on the Earth's surface. The latitude and longitude of that point is known as the celestial body’s geographic position (GP), the location of which can be determined from tables in the Nautical or Air Almanac for that year. The measured angle between the celestial body and the visible horizon is directly related to the distance between the celestial body's GP and the observer's position. After some computations, referred to as sight reduction, this measurement is used to plot a line of position (LOP) on a navigational chart or plotting work sheet, the observer's position being somewhere on that line. (The LOP is actually a short segment of a very large circle on the earth which surrounds the GP of the observed celestial body. An observer located anywhere on the circumference of this circle on the earth, measuring the angle of the same celestial body above the horizon at that instant of time, would observe that body to be at the same angle above the horizon.) Sights on two celestial bodies give two such lines on the chart, intersecting at the observer's position (actually, the two circles would result in two points of intersection arising from sights on two stars described above, but one can be discarded since it will be far from the estimated position—see the figure at example below). Most navigators will use sights of three to five stars, if they're available, since that will result in only one common intersection and minimize the chance for error. That premise is the basis for the most commonly used method of celestial navigation, and is referred to as the 'altitude-intercept method'. There are several other methods of celestial navigation which will also provide position finding using sextant observations, such as the noon sight, and the more archaic lunar distance method. Joshua Slocum used the lunar distance method during the first ever recorded single-handed circumnavigation of the world. Unlike the altitude-intercept method, the noon sight and lunar distance methods do not require accurate knowledge of time. The altitude-intercept method of celestial navigation requires that the observer know exact Greenwich Mean Time (GMT) at the moment of his observation of the celestial body, to the second—since every four seconds that the time source (commonly a chronometer or in aircraft, an accurate "hack watch") is in error, the position will be off by approximately one nautical mile...

Enjoy Dennis Hand's presentation on How Far Away Are the Stars? from December 2, 2016 to the Bays Mountain Astronomy Club. Dennis is an active observational astronomer. He taught astronomy and a few other subjects in the Greensboro City Schools. After his retirement, he made presentations to school groups at the Greensboro Natural Science Center for several years. Dennis currently serves as the chair of the Advisory Committee for Cline Observatory at Guilford Technical Community College and has been teaching astronomy at High Point University since 2008. He’s been a member of the Greensboro Astronomy Club since 1985. Dennis’s presentation will be titled, “How Far Away Are the Stars?” Since antiquity we’ve wondered about the stars. What are they made of? How far away are they? When asked today about the distances, it’s easy to say that Proxima Centauri is almost 13 trillion miles away. We point our telescopes at M31 and tell our guests that the Andromeda Galaxy is almost 3 million light years away. But how do we know? Dennis will take us on a journey through time to remember how we learned the distances to the stars. Beginning with Aristotle and Hipparchus we’ll rediscover the methods used to determine one of the most basic features of the night sky: How far away are the stars?

What Characteristics Of Stars Can Be Measured Using Luminosity?
 
00:46
The absolute magnitude is a measure of the stars luminosity---the total amount of energy radiated by the star every second. If you measure a stars apparent magnitude and know its absolute magnitude, you can find the stars distance (using the inverse square law of light brightness). The models that fit red giant's characteristics suggest they are ughghghg learn with flashcards, games, and more for free. In our models we find that choosing how much helium (and the trace amount of heavier elements) almost completely determines a star's temperature and luminosity. Star determining distances is crucial to understanding stars because we can use figure out. Stars flux, luminosity, color, and temperature. They provided early astronomers with a reference system for measuring the motions of planets ('wandering stars'), moon, and sun. Flux if we have a light detector (eye, camera, telescope) can measure the produced by star total amount of energy intercepted divided area is 2 nov 2010 absolute magnitude star's luminosity radiated every second.

Do Stars Move? Tracking Their Movements Across the Sky

Here’s to hundreds more. The night sky, is the night sky, is the night sky. The constellations you learned as a child are the same constellations that you see today. Ancient people recognized these same constellations. Oh sure, they might not have had the same name for it, but essentially, we see what they saw. But when you see animations of galaxies, especially as they come together and collide, you see the stars buzzing around like angry bees. We know that the stars can have motions, and yet, we don’t see them moving? How fast are they moving, and will we ever be able to tell? Stars, of course, do move. It’s just that the distances are so great that it’s very difficult to tell. But astronomers have been studying their position for thousands of years. Tracking the position and movements of the stars is known as astrometry. We trace the history of astrometry back to 190 BC, when the ancient Greek astronomer Hipparchus first created a catalog of the 850 brightest stars in the sky and their position. His student Ptolemy followed up with his own observations of the night sky, creating his important document: the Almagest. In the Almagest, Ptolemy laid out his theory for an Earth-centric Universe, with the Moon, Sun, planets and stars in concentric crystal spheres that rotated around the planet. He was wrong about the Universe, of course, but his charts and tables were incredibly accurate, measuring the brightness and location of more than 1,000 stars. A thousand years later, the Arabic astronomer Abd al-Rahman al-Sufi completed an even more detailed measurement of the sky using an astrolabe. One of the most famous astronomers in history was the Danish Tycho Brahe. He was renowned for his ability to measure the position of stars, and built incredibly precise instruments for the time to do the job. He measured the positions of stars to within 15 to 35 arcseconds of accuracy. Just for comparison, a human hair, held 10 meters away is an arcsecond wide. Also, I’m required to inform you that Brahe had a fake nose. He lost his in a duel, but had a brass replacement made. In 1807, Friedrich Bessel was the first astronomer to measure the distance to a nearby star 61 Cygni. He used the technique of parallax, by measuring the angle to the star when the Earth was on one side of the Sun, and then measuring it again 6 months later when the Earth was on the other side. Over the course of this period, this relatively closer star moves slightly back and forth against the more distant background of the galaxy. And over the next two centuries, other astronomers further refined this technique, getting better and better at figuring out the distance and motions of stars. But to really track the positions and motions of stars, we needed to go to space. In 1989, the European Space Agency launched their Hipparchus mission, named after the Greek astronomer we talked about earlier. Its job was to measure the position and motion of the nearby stars in the Milky Way. Over the course of its mission, Hipparcos accurately measured 118,000 stars, and provided rough calculations for another 2 million stars. That was useful, and astronomers have relied on it ever since, but something better has arrived, and its name is Gaia. Launched in December 2013, the European Space Agency’s Gaia in is in the process of mapping out a billion stars in the Milky Way. That’s billion, with a B, and accounts for about 1% of the stars in the galaxy. The spacecraft will track the motion of 150 million stars, telling us where everything is going over time. It will be a mind bending accomplishment. Hipparchus would be proud. With the most precise measurements, taken year after year, the motions of the stars can indeed be calculated. Although they’re not enough to see with the unaided eye, over thousands and tens of thousands of years, the positions of the stars change dramatically in the sky. The familiar stars in the Big Dipper, for example, look how they do today. But if you go forward or backward in time, the positions of the stars look very different, and eventually completely unrecognizable.

Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes. For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. Almost all naturally occurring elements heavier than helium are created by stellar nucleosynthesis during the star's lifetime, and for some stars by supernova nucleosynthesis when it explodes. Near the end of its life, a star can also contain degenerate matter. Astronomers can determine the mass, age, metallicity (chemical composition), and many other properties of a star by observing its motion through space, its luminosity, and spectrum respectively. The total mass of a star is the main factor that determines its evolution and eventual fate. Other characteristics of a star, including diameter and temperature, change over its life, while the star's environment affects its rotation and movement. A plot of the temperature of many stars against their luminosities produces a plot known as a Hertzsprung–Russell diagram (H–R diagram). Plotting a particular star on that diagram allows the age and evolutionary state of that star to be determined. Source of information: https://en.wikipedia.org/wiki/Star

Gaia 1
 
02:14
In the latter years of the 18th century, astronomers William and Caroline Herschel began to count stars. William called the technique 'star gauging' and his aim was to determine the shape of our Galaxy. Ever since 1609, when Galileo lifted his telescope to the misty patch of light known as the Milky Way and saw that it was composed of myriad faint stars whose light all blurred together, we have known that there are different numbers of stars in different directions throughout space. This means that our local collection of stars, the Galaxy, must have a shape to it. Herschel set out to find out what that shape was. He used a large telescope, twenty feet (610 cm) in length, mounted between tall wooden frames to sweep out a large circle in the sky that passed through the Milky Way at right angles. He then split this circle into more than 600 regions and counted or estimated the number of stars in each. With this simple technique the Herschels produced the first shape estimate for the Galaxy. Fast-forward to the 21st century and now researchers use star counts to search for hidden star clusters and satellite galaxies. They look for regions where the density of stars rises higher than expected. These patches are called stellar over-densities. Back in 1785, Herschel's circular track passed close to the brightest star in the night sky Sirius. Now, scientists mining the first data released from the ESA spacecraft Gaia have revisited that particular area of the sky and made a remarkable discovery. They have revealed a large star cluster that could have been discovered more than a century and a half ago had it not been so close to Sirius. Astronomers have been looking for star clusters and satellite galaxies in various surveys for the past decade. It was natural for them to do this with the Gaia mission's first data release. Gaia is the European Space Agency's astrometric mission. Collecting positions, brightnesses and additional information for more than a billion sources of light, its data allows nothing less than the most precise 'star gauging' ever. These days the laborious task of counting the stars is done by computers but the results still have to be scrutinised by humans. Astonomers were combing the list of over-densities when they saw the massive cluster. At first it seemed too good to be true. Bright stars can create false signals, termed artefacts, that astronomers must be careful not to mistake for stars. An early paper from the Gaia team had even discussed artefacts around Sirius using a nearby patch of sky to the one Koposov was looking at. These two objects were named: Gaia 1 for the object located near Sirius, and Gaia 2, which is close to the plane of our Galaxy, and both were duly published. Gaia 1 in particular contains enough mass to make a few thousand stars like the Sun, is located 15 thousand light years away, and spread across 30 light years. This means it is a massive star cluster. Collections of stars like Gaia 1 are called open clusters. They are families of stars that all form together and then gradually disperse around the Galaxy. Our own Sun very likely formed in an open cluster. Such assemblies can tell us about the star formation history of our Galaxy. Finding a new one that can be easily studied is already paying dividends. Identifying 41 members of the cluster, astonomerss found that Gaia 1 is unusual in at least two ways. Firstly, it is about 3 billion years old. This is odd because there are not many clusters with this age in the Milky Way. Typically clusters are either younger than a few hundred million years – these are the open clusters – or older than 10 billion years – these are a distinct class called globular clusters, which are found beyond the main bulk of stars in our Galaxy. Being of intermediate age, Gaia 1 might represent an important bridge in our understanding between the two populations. Secondly, its orbit through the galaxy is unusual. Most open clusters lie close to the plane of the Galaxy but Simpson found that Gaia 1 flies high above it before ducking down and passing underneath. About 90% of clusters never go more than a third of this distance. Simulations of clusters with orbits like Gaia 1 find that they are stripped of stars and dispersed by these high velocity 'plane passages'. That puts it at odds with the age estimate.

In short: in a galaxy of hundreds of billions of stars, each of which having billions of years to spawn life and civilization, isn’t it odd that none have made themselves apparent to us. Enrico Fermi was, supposedly, using this as an argument against the plausibility of interstellar travel. If aliens can travel between the stars, why haven’t they visited? But the paradox is much broader than this. There are several ways that an advanced civilization could give away their presence. Radio transmissions, robotic probes, or star-blotting solar arrays. A series of very recent surveys of our galaxy reveal none of the above, while at the same time proving the abundance of potentially habitable worlds. The Fermi paradox has become only more paradoxical, and these surveys are finally powerful enough to draw some serious conclusions about the rarity of advanced civilizations AND about the chance of us ever becoming one.

How We Know Black Holes Exist 2017
 
00:09
n the late 18th century, two scientists (John Michell and Pierre Simon Laplace) separately theorized that a star could be so massive that not even light could escape its surface. But nothing more was made of these “dark stars” until the 20th century, when Albert Einstein published his general theory of relativity. His idea turned the notion of gravity on its head: It isn’t really a push/pull force, but instead describes how mass affects the fabric of space-time. And general relativity made possible the reality of those dark stars. In 1916, just one year after Einstein published his theory, physicist Karl Schwarzschild calculated general relativity’s gravitational equations in an extreme case (when an object has a mass near infinity) and found that the fabric of space-time would fold in on itself, creating a “singularity” — a region with zero volume and infinite density. Such a point would not allow matter or even light to escape. Today’s term for this object — a black hole — came 50 years later, around the same time researchers began discovering hints of them. Now, after 40 years of research, scientists are positive these extremely dense bodies exist, and that there are two different types. Astronomers categorize black holes as either stellar mass (which range from three to tens of times our Sun’s mass and mark the end state of a massive star) or supermassive (which are millions to billions of times our star’s mass and sit at the centers of galaxies). The smaller variety Over the years, different methods have convinced scientists that both types of black holes exist. One of the most successful techniques astronomers have used to find both stellar and super-massive black holes is monitoring the movements of stars near suspected black holes. They use the visible companion in a binary system as a tracer. This method arose in the late 1960s – when X-ray detectors aboard satellites spotted sources of X-rays in our galaxy. Many of these changed brightness over fractions of a second, so astronomers called them “X-ray transients.” Scien-tists soon realized that some of these objects were binary systems. In X-ray binaries, if the two bodies are close enough, the compact object pulls hot gas from the star. The stellar material heats up to millions of degrees due to friction and emits X-rays. The unseen compact companion could be a neutron star or a black hole; both are small enough to appear “invisible” until gas falls onto them, which then heats up and produces a bright X-ray source. A black hole warps space-timeto the extreme, creating a point where the cosmic fabric folds in on itself. Any mass or light that comes within a certain distance — called the event horizon – will fall in and never escape. Click to zoom To distinguish between the possibilities, scientists need the invisible object’s mass, which they can determine using basic physics laws. Astronomers collect data through the visible star’s spectral emission, which tells them about the star’s composition and movement. As the star moves away from Earth in its orbit around its invisible companion, its – emission shifts slightly toward the red end of the electromagnetic spectrum; as it speeds toward our planet, its emission shifts to the blue end. From the amount the spectrum shifts, astronomers can determine how fast the visible star is moving and how long it takes to complete one orbit. Then, using the same law of physics that dictates how the planets orbit the Sun, they can calculate the mass of the unseen companion. A stellar-mass black hole is the last stage of evolution of a star that once was at least 30 times our Sun's mass. This black hole holds between about three and tens of solar masses crammed into an area about the size of a large city A stellar-mass black hole is the last stage of evolution of a star that once was at least 30 times our Sun’s mass.

Teach Astronomy - Parsec
 
00:57
http://www.teachastronomy.com/ A parsec is a distance unit appropriate to the study of stars. It's the distance that produces a parallax shift of one arcsecond. In other words, it's the distance where the angle subtended by the star as seen from the Earth's orbit six months apart, spanning the orbit, is one second of arc. One parsec equals 3.26 lightyears, so a parsec is slightly larger than a lightyear. Astronomers also use multiples of the parsec, a thousand parsecs, which is a kiloparsec, and a million parsecs, which is a megaparsec. The most useful thing about the parsec unit is that it corresponds to the typical distances between stars in the Milky Way Galaxy.

Wallace Thornhill: The Long Path to Understanding Gravity | EU2015
 
01:02:00
In the theoretical sciences, it is commonly assumed that the role of gravity is settled. But as Richard Feynman observed, “There is no model of the theory of gravitation today, other than the mathematical form.” The problem is that mathematics will not account for the essential force in question. And yet, when theorists speculate about the big bang one conjecture is followed by another all building on the supposed supremacy of gravity as the driving force of cosmic evolution. In this talk at the EU2015 conference, Wal Thornhill takes us on a forty-year personal journey to understand the role of gravity in the electric universe.

A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two or more stars are called multiple star systems. These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means. Research over the last two centuries suggests that half or more of visible stars are part of multiple star systems. The term double star is often used synonymously with binary star; however, double star can also mean optical double star. Optical doubles are so called because the two stars appear close together in the sky as seen from the Earth; they are almost on the same line of sight. Nevertheless, their "doubleness" depends only on this optical effect; the stars themselves are distant from one another and share no physical connection. A double star can be revealed as optical by means of differences in their parallax measurements, proper motions, or radial velocities. Most known double stars have not been studied sufficiently closely to determine whether they are optical doubles or they are doubles physically bound through gravitation into a multiple star system. Binary star systems are very important in astrophysics because calculations of their orbits allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated. This also determines an empirical mass-luminosity relationship (MLR) from which the masses of single stars can be estimated. Binary stars are often detected optically, in which case they are called visual binaries. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits which are uncertain or poorly known. They may also be detected by indirect techniques, such as spectroscopy (spectroscopic binaries) or astrometry (astrometric binaries). If a binary star happens to orbit in a plane along our line of sight, its components will eclipse and transit each other; these pairs are called eclipsing binaries, or, as they are detected by their changes in brightness during eclipses and transits, photometric binaries. If components in binary star systems are close enough they can gravitationally distort their mutual outer stellar atmospheres. In some cases, these close binary systems can exchange mass, which may bring their evolution to stages that single stars cannot attain. Examples of binaries are Sirius, and Cygnus X-1 (Cygnus X-1 being a well-known black hole). Binary stars are also common as the nuclei of many planetary nebulae, and are the progenitors of both novae and type Ia supernovae.

Why do planets occasionally move backward in the night sky? This video explains the phenomena known as retrograde motion. (Spoiler Alert): The apparent backward or 'retrograde' motion of the planets is cause by nothing more than the optical illusion known as parallax. Simply put, parallax is the apparent change of position of an object when viewed from different positions. Imagine you are in a car traveling on the highway and looking out the side window - the street lamps close to you appear as if they are moving backyard extremely fast, whereas the trees 50 meters away appear to be moving slower, and the trees in the distance are hardly moving at all (of course the street lamps and trees aren't moving backward at all they only appear to be moving.) The closer an object is to our viewpoint, the more parallax will occur relative to further away objects. Scientist even use this method to determine the distance to far away stars. As the earth moves from one side of the sun to the other (a sideways distance of approximately 300,000,000 km) stars display 'stellar parallax' - close stars display more parallax than stars further away. You might think to yourself that it should be easy to determine if an object has apparent motion or true motion (ie. how do you know if YOU are moving and the object is stationery, or if the OBJECT is moving and you are stationery.) As an example, if you have ever been on a train sitting at a station with another train right next to you, when one of the trains begins moving, it can often be very hard to tell if you are moving forward or the train next to you is moving backward! In regards to earth and mars, both planets are in motion and moving in the same direction, however earth is moving FASTER than mars, and therefore it overtakes it. If we go back to the car analogy, imagine you are traveling on the highway at 100km/h and you are overtaking a car that is only traveling at 80km/h. although the other a car is traveling at 80km/h, from your perspective the car can appear to be moving backwards as you pass it! Motion and speed are all relative - something that appears to be moving backward to one person, can appear to be moving forwards to another person who is viewing it from an different reference frame. If all of this still doesn't make any sense to you, try this simple experiment: place an object (e.g a bottle of water) on the table and move your face very close to it. Now move your head from one side of the bottle to the other. The bottle will appear to be moving a greater distance than the objects behind it, simply because it's the closest thing to you. That is the optical illusion parallax. My chenal Technical things

Frontiers of Physics Lecture Series: Dr. David Charbonneau, Fall 2018
 
01:30:04
The NASA Kepler Mission taught us that Earth-sized planets are a commonplace throughout the Galaxy. But did life take root on any of these distant worlds? Using upcoming large telescopes, astronomers will search the atmospheres of Earth-like planets for the telltale chemical fingerprints of life. ABOUT THE SPEAKER Dr. David Charbonneau is a Professor of Astronomy at Harvard University. Dr. Charbonneau's research focuses on the detection and characterization of exoplanets with the goal of studying inhabited worlds. He led the team that made the first detection of the passage of an exoplanet across its parent star; the first detection of an exoplanet atmosphere; and the first detection of light emitted by a planet outside the solar system. Using data from the NASA Kepler Mission, Dr. Charbonneau and his student Courtney Dressing determined the Galactic frequency of occurrence of planets that were similar to Earth in both size and temperature. He currently leads the MEarth Project, which has found several of the terrestrial exoplanets whose atmospheres are amenable to study, and he is a Co-Investigator on the NASA TESS Mission, which launched in April 2018. Dr. Charbonneau has received numerous awards for his research, including the Alan T. Waterman Award from the NSF and the Medal for Exceptional Scientific Achievement from NASA, and is a member of the National Academy of Sciences. He earned his Ph.D. in Astronomy from Harvard University, and his B.Sc. in Math, Physics, and Astronomy from the University of Toronto. This lecture was held at the University of Washington for the Froniters of Physics Lecture Series.

Andrew Hall: The Arc-Blasted Earth | EU2016
 
43:20
EU2017: Future Science -- Rebroadcast — only $29: https://www.electricuniverse.live In a well-received presentation, Andrew Hall showed the audience a new geologic idea about mountain formation based on the Electric Universe model. His new concept includes the following: 1) Triangular buttresses form on the sides of mountains in the shape of reflected supersonic shock waves. 2) They are layered onto the mountain; thus, they are not caused by seismic waves. 3) They are layered perpendicular to the wind direction, consistent with supersonic winds created by shock waves. 4) The triangular waveforms are parallel to the primary shock pattern, consistent with reflected shock waves. 5) The triangular waveforms exhibit less energy and more transient effects on softer substrates and higher energy, sharper angles on hard substrates. 6) They are not layered sediments from an ancient beach, or waterway since triangles are a consistent feature around the world and do not conform to any motion of random water waves. 7) They are formed in all types of rock, including granite; thus, they are not formed by eons of normal winds. 8) The triangular waveforms exhibit compression and expansion from superimposed longitudinal and transverse waves that came from a source above.
