Science & Reason on Facebook: http://tinyurl.com/ScienceReason Star Size Comparison: The biggest/largest known stars in the Universe. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- VY Canis Majoris (VY CMa) is a red hypergiant star located in the constellation Canis Major. With a size of 2600 solar radii, it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth. Unlike most stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of 6,275,081 days, or just under 17,200 years. Antares is a red supergiant star in the Milky Way galaxy and the sixteenth brightest star in the nighttime sky (sometimes listed as fifteenth brightest, if the two brighter components of the Capella quadruple star system are counted as one star). Along with Aldebaran, Spica, and Regulus it is one of the four brightest stars near the ecliptic. Antares is a variable star, whose apparent magnitude varies from +0.9 to +1.8. The Pistol Star is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates. It is located approximately 25,000 light years from Earth in the direction of Sagittarius. It would be visible to the naked eye as a fourth magnitude star, if it were not for the interstellar dust that completely hides it from view in visible light. Rigel (β Ori / β Orionis / Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18. Although it has the Bayer designation "beta", it is almost always brighter than Alpha Orionis (Betelgeuse). Aldebaran (α Tau, α Tauri, Alpha Tauri) is an orange giant star located about 65 light years away in the zodiac constellation of Taurus. With an average apparent magnitude of 0.87 it is the brightest star in the constellation and is one of the brightest stars in the nighttime sky. The name Aldebaran is Arabic (الدبران al-dabarān) and translates literally as "the follower", presumably because this bright star appears to follow the Pleiades, or Seven Sisters star cluster in the night sky. This star is also called the Bull's Eye because of its striking orange color and its location in the bull's head shaped asterism. NASA's Pioneer 10 spacecraft, which flew by Jupiter in 1973, is currently traveling in the direction and will reach it in about two million years. Arcturus (α Boo / α Boötis / Alpha Boötis) is the brightest star in the constellation Boötes. With a visual magnitude of −0.05, it is also the third brightest star in the night sky, after Sirius and Canopus. It is, however, fainter than the combined light of the two main components of Alpha Centauri, which are too close together for the eye to resolve as separate sources of light, making Arcturus appear to be the fourth brightest. It is the second brightest star visible from northern latitudes and the brightest star in the northern celestial hemisphere. The star is in the Local Interstellar Cloud. Pollux (β Gem / β Geminorum / Beta Geminorum) is an orange giant star approximately 34 light-years from the Earth in the constellation of Gemini (the Twins). Pollux is the brightest star in the constellation, brighter than Castor (Alpha Geminorum). As of 2006, Pollux was confirmed to have an extrasolar planet orbiting it. Sirius is the brightest star in the night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name Sirius is derived from the Ancient Greek Σείριος. The star has the Bayer designation α Canis Majoris (α CMa, or Alpha Canis Majoris). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The Sun is the star at the center of the Solar System. The Sun has a diameter of about 1,392,000 kilometres (865,000 mi) (about 109 Earths), and by itself accounts for about 99.86% of the Solar System's mass; the remainder consists of the planets (including Earth), asteroids, meteoroids, comets, and dust in orbit. About three-fourths of the Sun's mass consists of hydrogen, while most of the rest is helium. http://en.wikipedia.org/wiki/Largest_stars --- CREDITS Animations: morn1415, NASA, ESO, Hubblecast Editing: http://www.youtube.com/Best0fScience .

#solarsystem #theuniverse #documentary A solar system is a star and all of the objects that travel around it—planets, moons, asteroids, comets and meteoroids. Most stars host their own planets, so there are likely tens of billions of other solar systems in the Milky Way galaxy alone. Solar systems can also have more than one star. These are called binary star systems if there are two stars, or multi-star systems if there are three or more stars. Please support me: https://teespring.com/stores/gpks-store

Exploring Stars in Our Galaxy - Full Documentary
 
01:00:25
Exploring The Southern Stars - Full Documentary "Billions and billions" of stars in a galaxy (after a quote often mistakenly attributed to Carl Sagan) is how many people imagine the number of stars you would find in one. Is there any way to know the answer for sure? "It's a surprisingly difficult question to answer. You can't just sit around and count stars, generally, in a galaxy," said David Kornreich, an assistant professor at Ithaca College in New York State. He was the founder of the "Ask An Astronomer" service at Cornell University. Even in the Andromeda Galaxy — which is bright, large and relatively close by Earth, at 2.3 million light-years away — only the largest stars and a few variable stars (notably Cepheid variables) are bright enough to shine in telescopes from that distance. A sun-size star would be too difficult for us to see. So astronomers estimate, using some of the techniques below. Advertisement Massive investigation The primary way astronomers estimate stars in a galaxy is by determining the galaxy's mass. The mass is estimated by looking at how the galaxy rotates, as well as its spectrum using spectroscopy. All galaxies are moving away from each other, and their light is shifted to the red end of the spectrum because this stretches out the light's wavelengths. This is called "redshift." In a rotating galaxy, however, there will be a portion that is more "blueshifted" because that portion is slightly moving toward Earth. Astronomers must also know what the inclination or orientation of the galaxy is before making an estimate, which is sometimes simply an "educated guess," Kornreich said. A technique called "long-slit spectroscopy" is best for performing this type of work. Here, an elongated object such as a galaxy is viewed through an elongated slit, and the light is refracted using a device such as a prism. This breaks out the colors of the stars into the colors of the rainbow. Some of those colors will be missing, displaying the same "patterns" of missing portions as certain elements of the periodic table. This lets astronomers figure out what elements are in the stars. Each type of star has a unique chemical fingerprint that would show up in telescopes. (This is the basis of the OBAFGKM sequence astronomers use to distinguish between types of stars.) Any kind of telescope can do this sort of spectroscopy work. Kornreich often uses the 200-inch telescope at the Palomar Observatory at the California Institute of Technology, but he added that almost any telescope of sufficient size would be adequate. The ideal would be using a telescope in orbit because scattering occurs in Earth's atmosphere from light pollution and also from natural events — even something as simple as a sunset. The Hubble Space Telescope is one observatory known for this sort of work, Kornreich added. The number of stars is approximately … So is there any way to figure out how many stars are for sure? In the end, it comes down to an estimate. In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out. Other mass estimates bring the number up to 400 billion. The caveat, Kornreich said, is that these numbers are approximations. More advanced models can make the approximation more accurate, but it would be very difficult to count the stars one by one and tell you for sure how many are in the galaxy.

Andromeda Stars in Your Eyes
 
03:45
A perfectly magical video from HubbleCast, with the famous Dr. J. The Andromeda Galaxy is revealed in unprecedented detail in four archive observations from the NASA/ESA Hubble Space Telescope. They show stars and structure in the galaxy's disc, the halo of stars that surrounds it, and a stream of stars left by a companion galaxy as it was torn apart and pulled in by the galaxy's gravitational forces. Images from Hubble Space Telescope have unparalleled image quality as a result of the telescope's position above the atmosphere. Secondly, M 31 is closer to our own galaxy than any other spiral galaxy (so close that it can even be seen with the naked eye on a very dark night. And thirdly, these observations avoid the crowded centre of the galaxy, where the stars are closest together and hardest to separate from each other. The resulting images offer a different perspective on a spiral galaxy. Far from being an opaque, dense object, Hubble reminds us that the dominant feature of a galaxy is the huge voids between its stars. Thus, these images do not only show stars in the Andromeda Galaxy (and a handful of bright Milky Way stars that are in the foreground): they also let us see right through the galaxy, revealing far more distant galaxies in the background. The two images taken in M 31's halo show the lowest density of stars. The halo is the huge and sparse sphere of stars that surrounds a galaxy. While there are relatively few stars in a galaxy's halo, studies of the rotation rate of galaxies suggest that there is a great deal of invisible dark matter. Meanwhile, the images of stars in the Andromeda Galaxy's disc and a region known as the giant stellar stream show stars far more densely packed, largely outshining the background galaxies. The galaxy's disc includes the distinctive spiral arms (as well as dimmer and less numerous stars in the gaps between them), while the stream is a large structure which extends out from the disc, and is probably a remnant of a smaller galaxy that was absorbed by the Andromeda Galaxy in the past. These observations were made between 2004 and 2007 to observe a wide variety of stars in Andromeda, ranging from faint main sequence stars like our own Sun, to the much brighter RR Lyrae stars, which are a type of variable star. With these measurements, astronomers can determine the chemistry and ages of the stars in each part of the Andromeda Galaxy.

Dear world, Let´s talk about time. When I uploaded my first YouTube video 7 years ago, I would have never thought that it would get that much attention. Had lots of discussions, met new people, continued to make videos about things that intrigued me. Or tried out effects. I enjoyed it a lot, and I still read every comment that pops up. And they keep coming in. It is a hobby that I am very glad about having started. And I am humbled by the attention. Well, as time went by I found less time to work on videos, struggled with other things in life, and wondered if I would ever find the time again. But I always knew one thing: I owe you something. All the time people were are asking about a sequel to starsize comparison. And yes, I promised once. I keep my promises. So, whenever I found time over the last year I spent it on that. Here it is. I hope you like it. I tried to do it in a bit different way. Curious for the feedback. I know I will be hardly able to beat the choice of music from the first part, but let me say, Vangelis Alpha is a piece that is very dear to my heart, I always had this in mind. Still looking for contact to musicians. I do not know what the future brings, but I hope we will hear from each other. Enjoy.

While the spatial size of the entire Universe is still unknown, it is possible to measure the observable universe. The earliest scientific models of the Universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the centre of the Universe. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the centre of the Solar System. In developing the law of universal gravitation, Sir Isaac Newton built upon Copernicus's work as well as observations by Tycho Brahe and Johannes Kepler's laws of planetary motion. Further observational improvements led to the realization that our Sun is one of hundreds of billions of stars in a galaxy we call the Milky Way, which is one of hundreds of billions (perhaps trillions[which?]) of galaxies in the Universe. Many of these stars have planets. At the largest scale galaxies are distributed uniformly and the same in all directions, meaning that the Universe has neither an edge nor a center. At smaller scales, galaxies are distributed in clusters and superclusters which form immense filaments and voids in space, creating a vast foam-like structure.Discoveries in the early 20th century have suggested that the Universe had a beginning and that space has been expanding since then, and is currently still expanding at an increasing rate. *Keywords: UNIVERSE COMPARISON, UNIVERSE COMPARISON 3D COMPARISON OF UNIVERSE, SYSTEM SOLAR SIZE COMPARISON, COMPARISON OF SOLAR SYSTEM, GALAXY COMPARISON , COMPARISON OF GALAXIES, GALAXIES COMPARIOSN, STAR SIZE COMPARISON, STAR COMPARISON, STARS COMPARISON, COMPARISON OF STARS SIZE, COMPARISON OF STAR,Space comparison, Comparison of space Black holes Comparison, Black hole comparison, Comparison of black holes, First Photo of black hole,

Milky Way Versus Andromeda As Seen from Earth
 
03:53
From HubbleCast. Scientists have been using Hubble observations to predict the future of the Andromeda Galaxy and the Milky Way, and how the collision will look from Earth. Projecting the motion of Andromeda's stars over the next 8 billion years, the astronomers now know the path that galaxy is taking through space. And it's heading straight for us! Computer simulations based on Hubble observations show how the two galaxies will crash together in around 4 billion years' time. The Andromeda Galaxy, some 2.2 million light-years away, is the closest spiral galaxy to our home, the Milky Way. For around a century, astronomers have known it is moving towards us, but whether or not the two galaxies would actually collide, or simply fly past each other, remained unclear. Now, a team of astronomers has used the Hubble Space Telescope to shed light on this question, by looking at the motion stars in the Andromeda Galaxy. We wanted to figure out how Andromeda was moving through space. So in order to do that we measured the location of the Andromeda stars relative to the background galaxies. In 2002 they were in one place, and in 2010 they were in a slightly different place. And that allowed us to measure the motion over a period of eight years. The motion is actually incredibly subtle, and not obvious to the human eye, even when looking at Hubble's sharp images. However, sophisticated image analysis revealed tiny movements that the scientists were able to project into the future. Based on these findings, it is finally possible to show what will happen to the Milky Way over the next eight billion years, as the galaxies drift closer, then collide and gradually merge into a single, larger, elliptical galaxy with reddish stars. And yet the Solar System should in fact survive this huge crash. The reason we think that our Solar System will not be much affected by this collision between the Milky Way and Andromeda is that galaxies are mostly empty space. Even though our galaxy, as well as the Andromeda Galaxy, has a hundred billion stars in it, they are very far apart. So if two galaxies actually collide with each other, the stars basically pass right between each other and the chance of two stars directly hitting each other is really, really small. So the likelihood that our Solar System will be directly impacted by another star, for example, in Andromeda as we collide with it is really, really small. Well, if life is still present on Earth when this happens, the changes in the sky will be quite spectacular. Now they will be very very slow because the timescales on the scales of galaxies in the Universe are very very long. So you have to think, millions of years but even then over these timescales over millions of years, we will see big changes. If we wait a few billion years, Andromeda will be huge on the sky. It will be as big as our Milky Way because we'll be very close to it. And then later, when the galaxies merge, the merged remnant of the Milky Way Galaxy and Andromeda will look more like an elliptical galaxy and we'll be sitting right in it. So the view of the Milky Way on the night sky will be completely gone and this band of light will be replaced by a more spheroidal distribution of light. And so, the Sun, born in the Milky Way almost 5 billion years ago will end its life in a new orbit, as part of a new galaxy.

The Most Distant Galaxy in the Universe So Far
 
04:24
From ESOCast: An international team of astronomers using ESO's Very Large Telescope has measured the distance to the most remote galaxy so far. This is the first time that astronomers have been able to confirm that they are observing a galaxy as it was in the era of reionization — when the first generation of brilliant stars was making the young Universe transparent and ending the cosmic Dark Ages. We are going to find out how a team of astronomers used ESO's Very Large Telescope, the VLT, to confirm that a galaxy that had previously been spotted in images from the NASA/ESA Hubble Space Telescope is in fact the most distant object that is ever been identified in the Universe. Studying these first galaxies is extremely difficult; they are very faint and small and by the time their dim light gets to Earth it falls mostly in the infrared part of the spectrum because it has been stretched by the expansion of the Universe. To make matters worse, at this very early time, less than a billion years after the Big Bang, the Universe was not completely transparent. It was filled with hydrogen which acted kind of like a fog and absorbed the ultraviolet radiation from the young galaxies. So, holding the record for having measured the redshift of the most distant object in the Universe is not just a trophy to hang on the wall, it does have important astrophysical implications. This is the first time that we've managed to obtain spectroscopic observations of a galaxy from the era of reionization, in other words from the time when the Universe was still clearing out the hydrogen fog. Despite the difficulties of finding these early galaxies, the new Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope discovered several very good candidate objects earlier in 2010. They were thought to be galaxies shining in the early Universe at redshifts greater than eight, but confirming the distances to such faint and remote objects is an enormous challenge and can only reliably be done using spectroscopy from very large ground-based telescopes. The team was excited to find that if you combine the huge light collecting power of the VLT, with the sensitivity of its infrared spectroscopic instrument, SINFONI, and if you then use a very long exposure time you just might be able to detect the faint glow from one of these very remote objects and then go on to measure its distance. A 16 hour exposure with the VLT and SINFONI of the galaxy UDFy-38135539 did indeed show the very faint glow from hydrogen at a redshift of 8.6, which means that this light left the galaxy when the Universe was only about 600 million years old. This is the most distant galaxy ever reliably confirmed. One of the puzzling things about this discovery is that the ultraviolet radiation emitted by the galaxy does not actually seems to be strong enough to be able to clear out the hydrogen fog around the galaxy. So one possible explanation is that there must be other galaxies, probably fainter and less massive neighbours, that helped ionize the hydrogen in the region of space around the galaxy, thus making it transparent. Without this additional help the brilliant light from the main galaxy would have been trapped in the surrounding hydrogen fog and it could not have even started its 13 billion-year journey towards Earth. Studying the era of reionization and the formation of the first galaxies is really pushing the capability of current telescopes and instruments to the limit. But, this will be exactly the type of science that ESO's European Extremely Large Telescope will excel at. Once operational, this will be the largest optical and infrared telescope in the world.

Check out more awesome BuzzFeedBlue videos! http://bit.ly/YTbuzzfeedblue1 “There are more stars in our Universe than there are grains of sand on all the beaches on Earth.” There are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros. At the high end, it’s 200 sextillion. These are mind bogglingly huge numbers. How do they compare to the number of grains of sand on the collective beaches of an entire planet? This type of sand measures about a half millimeter across. You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter. If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers. And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across. If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close. So, is there that much sand on all the beaches, everywhere, on this planet? You’d need to estimate the average volume of a sandy beach and the average amount of the world’s coastlines which are beaches. The estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude are that, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

11 Incredible New Space Discoveries
 
08:02
11 amazing new discoveries made by astronomers and scientists from twin stars to a shocking triple star system, here are the facts! Subscribe for new videos Monday Wednesday and Friday! 6. A Triple Star System Last month in July, researchers found a new planet that simultaneously orbits 3 stars at once in a triple star system. The new planet titled HD 131399Ab is located in the constellation Centaurus, which is approximately 340 light years from Earth. Scientists have calculated that if someone were to look up from the planet the three orbiting stars would appear as full and bright as the full moon does here on earth. As a point of reference, Star A is about 80 percent larger and almost 8 times brighter than our own sun. The stars are visible for only 550 earth years of the planet’s orbit, which means a full orbit is 1,100 earth years! This new find shows that planets are able to exist in different layouts than what is believed 5. The Expansion of the Universe A couple of months ago it was announced that researchers had discovered that the universe is expanding at a much faster rate than what was initially thought. They were able to determine that its expansion is around 5 to 9 percent greater than what was previously expected. The rate of the universe’s expansion is known as the Hubble Constant, named after the famous American astronomer Edwin Hubble, which is now at a value of 45.5 miles per second per megaparsec. And to give a better understanding, a megaparsec is the equivalence of 3.26 million light years. This could help aid in the understanding of materials such as dark matter, dark energy, and dark radiation. 4. A White Dwarf Time Bomb This alluring image was captured by the Hubble Telescope that depicts the aftermath of an exploding white dwarf. The star had detonated 160,000 light-years away and what we can see are the hot gases being blasted throughout space. Now this supernova wasn’t caused by the star running out of hydrogen, as is the case with half of supernova explosions, but rather as a result of stealing. That’s right, the white dwarf was on it’s way to burning out when it managed to steal the neighboring gasses from a nearby star and create a new outer layer in the process. This made the star grow and become too unstable, resulting in a massive eruption. 3. Twin Stars It was discovered in late 2014 that what astronomers initially believed was one giant mass was really two separate stars that were orbiting each other very closely at a speed of 621,000 miles per hour. The two blue stars, both named MY Camelopardalis, have been identified as being incredibly much youngerーthey’re only 2 million years oldーthan most of the other formed stars and are each roughly 30 times bigger than our sun. This is one of the largest binary star systems that we know of. These two stars are set to eventually collide and form one giant star, which is how scientists believe a lot of the older stars in the universe came to be, however, no one knows when. 2. Dragonfly 44 What separates this galaxy from our very own Milky Way is that Astronomers have discovered that it is almost entirely made up of dark matter, 99.99 percent of it to be exact. For those of you who don’t know, dark matter is an invisible and mysterious material that has puzzled scientists for years. They aren’t quite sure what it is but they believe it’s real because of the effects its gravity has on the other things in space and it makes up about 80 percent of the universe. The galaxy was first spotted back in 2015 with the help of the Dragonfly Telephoto Array in New Mexico that is able to look at objects in space that aren’t bright enough for other telescopes. The array achieves this by using a combination of eight telephoto lenses and cameras. 1. Centauri B Astronomers have recently discovered that there is an Earth-sized planet that lies orbiting the red dwarf star known as Proxima Centauri. The planet dubbed as Centauri b is located 4.2 light years from our own solar system and is said to be found in the star’s “habitable zone”. Researchers have been trying to look for planets near Proxima Centauri for the last 15 years but have had no such luck, until now. How did this planet go undetected for so long when astronomers have found other planets that are located even further than Centauri b? The reason is said to be “sparse sampling and the longer term variability of the star”. Either way, scientists are now going to focus their efforts to see if there is any potential here to support life.

Why Are Most Galaxies Spiral-Shaped?
 
03:54
The structure of spiral galaxies is more complex than we thought. Here's how the laws of physics contribute to the shaping of galaxies. Everything We Know About The Andromeda Galaxy - http://bit.ly/2blkOkG Sign Up For The Seeker Newsletter Here - http://bit.ly/1UO1PxI Read More: What Process Creates And Maintains The Beautiful Spiral Arms Around Spiral Galaxies? I've Been Told That Density Waves Are Responsible -- So Where Do The Density Waves Come From? http://www.scientificamerican.com/article/what-process-creates-and/ ""The basic physics of why galaxies have spirals is known, but the details remain controversial, sometimes intensely so. Spirals exist only among flattened or 'disk' galaxies. These galaxies are differentially rotating--that is, the time to complete a full rotation increases with distance from the center. Differential rotation causes any disturbance in the disk to wind up into a spiral form. The trouble with this simple explanation is that the differential rotation would cause spiral features to wind up too quickly, so galaxies would not look like spirals for any appreciable length of time." How Do Spiral Galaxies Keep Their Shape? http://earthsky.org/space/how-do-spiral-galaxies-keep-their-shape "Astronomers sometimes call this the "wind-up problem" of the spiral arms. It has been observed that the inner parts of galaxies rotate faster than the outer parts. If so, are the inner parts of the spiral arms moving faster than the other parts? If that is happening, then the galaxy would have no choice but to wind up so much that the spiral structure would be thinned out and ultimately destroyed. But we can see galaxies billions of light-years away - as well as those relatively nearby - that have maintained their spiral structure. How?" Astrophysicists Discover Mechanism For Spiral-Arm Formation In Disk Galaxies http://phys.org/news/2016-08-astrophysicists-mechanism-spiral-arm-formation-disk.html "Astrophysicists at the University of Arkansas have discovered a mechanism for the formation of the spiral arms in disk galaxies. The finding was published in the Astrophysical Journal Letters, the journal of the American Astronomical Society. The discovery provides a better understanding for the formation of spiral arms in a kind of disk galaxy known as a spiral galaxy, said Hamed Pour-Imani, a physics doctoral student at the U of A and lead author of the study." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

After a brief history of what we thought going into the 20th century and how that changed, we give a high-level description of the three main components: the galactic center with its black hole, the galactic disk with its spiral arms, and the galactic halo stretching far out in all directions. Using the full power of the Hubble, Spitzer, and Chandra space telescopes, we take a deep dive into the center of our galaxy with its central bulge. We detail the evidence for the existence of a supermassive black hole, Sagittarius A*, at the very center of the galaxy's core. We cover and illustrate the work done by the UCLA Galactic Centre Group in conjunction with the new Keck observatory on top of the Mauna Kea volcano in Hawaii, and the Max Plank Institute for Extraterrestrial Physics in Germany. This includes the obits of S0-2 and S0-102 as they approach Sag A*. A look at the G2 Gas Cloud as it approaches Sag A* is also included. Next, we go a level deeper into the nature of a Black Hole singularity. We review electron exclusion pressure and neutron exclusion pressure forces that hold back gravity for White Dwarfs and Neutron stars respectively. When that isn't enough, we get the collapse is total. We cover the Schwarzschild radius, event horizon, accretion disk and gamma-ray jets. In addition to the supermassive black hole Sag A*, we show a few of the solar mass black hole candidates including A0620-00, and GRO J1655-40. We then cover the structure of the galactic disk including: the bar core, the two 3 Parsec arms, Scutum-Centaurus, Perseus, Sagittarius with its Orion Spur, Norma and the Outer Arm. We review the locations of various celestial objects we've seen in previous Milky Way segments, to show how close to us they are. We also cover the disk's rotation and the Sun's orbit. We end the galactic disk coverage by illustrating how far one would have to go to take a picture that would include what we see in our illustrations. Next, we cover the galactic halo. We start with Sharpley's globular cluster map that first showed that we were not at the center of the galaxy. We cover the size of the halo, the inner and outer halos orbital motion, and recent discoveries of massive amounts of Hydrogen in the halo and this findings impact on the Dark Matter debate. We conclude with another look at the distance ladder that took us across the galaxy. STEM
