GALAXIES

The Universe started in the Big Bang and ever since then space has been expanding - increasing the distance between galaxies ever since. Galaxy mergers are also very common though - so how does this happen if galaxies are always moving apart from each other? #bigquestions My book ' Space: 10 Things You Should Know' is out NOW worldwide (except for US & Canada - more info soon) you can find it in your local bookshop or order it here: http://bit.ly/SpaceDrBecky ----------- Follow me on Twitter: https://twitter.com/drbecky_ And on Instagram: https://www.instagram.com/drbecky_s/ Don't forget to subscribe and click the little bell icon to be notified when I post a new video! --------- Dr Becky Smethurst is an astrophysicist researching galaxies and supermassive black holes at Christ Church at the University of Oxford. http://drbecky.uk.com

How can scientists study galaxies so far away that they’re beyond the reach of the most powerful space telescopes? They take advantage of natural cosmic telescopes called gravitational lenses, illustrated in this new video. Using the Webb telescope like a time machine, astronomers will peer back billions of years to study how stars like our Sun formed in the early universe. Astronomers will examine the lensed, magnified light from very distant galaxies that are at or near the peak of star formation. Learn how: https://go.nasa.gov/2zdvGKm Credits: L. Hustak (STScI)

A recent discovery suggests a quasar might not be the signal of a galaxy's death.

As the powerful gravity of a supermassive black hole sucks in material, it can create a ring of superheated matter brighter than a galaxy itself called a quasar. Because a quasar is so bright and can be seen from so far away, quasars looks almost like stars, hence the name, which comes from “quasi-stellar radio source.” Astronomers long thought that a quasar was the signal of a galaxy’s demise, the sign of a passive dead galaxy where no more stars will form.That’s because the magnetic field surrounding the gas can get twisted up, steering gas away from the black hole and launching it into space, shutting off the gas supply the galaxy needs to form new stars. Quasars only last as long as their fuel source allows, and after they run out of gas a faint galaxy is all that’s left behind. But is it possible, somewhere in that span, the galaxy gets one last hurrah? The recent discovery of cold quasars has changed how we think galaxies end their life cycles.

This video pans over NASA/ESA Hubble Space Telescope observations of the galaxy ESO 495-21, about 30 million light-years from Earth. The galaxy is classified as a dwarf starburst galaxy — despite its tiny size the galaxy is producing new stars at a fiercy rate. The pan shows the many young, hot and blue stars being formed as well as the huge reservoirs of gas for even more stars. In the centre of the galaxy, invisible even to Hubble, lurks a supermassive black hole — an unusual component for a galaxy of this size.

What are quasars? Are Black Holes Really Black? Dr. Allison Kirkpatrick, astrophysicist at the University of Kansas, recently announced her discovery of cold quasars a new object in the field of astronomy — galaxies featuring an abundance of cold gas that can produce new stars despite having a quasar at the center. The breakthrough finding overturns assumptions about the end state of galaxies and may represent a phase of the death of a galaxy that was previously unknown. John Michael Godlier spoke to Dr. Kirkpatrick about this discovery as well as the future of the Milky Way galaxy and its eventual merger with Andromeda. Discussing if we will need to worry about a future where our galaxy becomes a quasar and earth possibly becomes in the path of a blazar. As well as how supermassive black holes collide, if black holes are really black and how black holes can get ejected due to collisions and wander through the universe unseen.

Ha, who am I kidding. It turns out they may be responsible for ending star formation across the entire universe. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer Directed by Andrew Kornhaber Produced By: Kornhaber Brown When we first realized that black holes could have masses of millions or even billions of times that of the sun, it came as a bit of a shock. They were discovered as the driving force behind quasars, where matter is heated to extreme incandescence before its plunge into vast black holes. But if that weren’t enough, we soon realized that every single decent-sized galaxy contains such a supermassive black hole. By the beginning of the 21st century it became clear that black holes and the galaxies that contain them are very closely connected. The bigger the galaxy, the bigger its supermassive black hole. That might not sound surprising. What was weird was how closely they were connected. There’s a tight correlation between the mass the central black hole and the mass of the stars in the galactic bulge – that’s the central ball-like part of a spiral galaxy, or the entirety of an elliptical galaxy, and every bulge contains a supermassive black hole around one-one-thousandth its mass. And there’s an even tighter relationship between the black hole mass and the speed that stars are moving in their random orbits within the galactic bulge – the so-called stellar velocity dispersion – which itself depends of the total mass of the galaxy, including dark matter.

Hello and welcome! My name is Anton and I'm currently away until late March, check the video here to learn why: https://www.youtube.com/watch?v=0ufoxL-eDJQ So as a result, I left some pre-recorded videos so you don't miss me too much and in this video I compiled several older videos many of you haven't seen into one big one ordered chronologically - this was you get to see what we've discovered in the last few years. The topic for this video is GALAXIES. This is an experimental long video that I wanted to try to see if my wonderful subscribers would like to see more of. I made a few topics that will be coming out in the next few days.

Astronomers have discovered a galaxy, called NGC 3079, is blowing bubbles in space and acting as an extraordinary particle accelerator. These "superbubbles" are likely being blown by outbursts powered by material falling onto supermassive black hole at the center of the galaxy or by winds from young stars. Stretching thousands of light years across, the superbubbles in NGC 3079 are seen in X-ray, optical, and radio emission. The particles in these superbubbles can be over a hundred times more energetic than those created by the world's most powerful accelerator, the Large Hadron Collider. Astronomers thinksuperbubbles like those in NGC 3079 may be the source of extremely energetic cosmic rays. Scientists have long been trying to track down all sources of cosmic rays, high-energy particles that regularly bombard the Earth.

Scientists using the Low-Frequency Array (LOFAR) telescope in the Netherlands have detected more than 300,000 galaxies that couldn't be seen by previous technology. CBSN's Tanya Rivero has more.

The gravity between them is a stronger force than expansion. - The rate of expansion is accelerating. If it continues to speed up, its force may become strong enough pull things apart that are currently held together by superior forces: Our galaxy, the solar system, and even the atoms in our bodies. That possible ending to the universe is known as the 'Big Rip'. Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars.

Does that somehow mean that the Big Bang works differently in different parts of the universe? And the answer simply is: no. Space is expanding because of the Big Bang. All of space is expanding in every direction all at once and from our viewpoint that means that it looks like all the other galaxies are moving away from us. But not all the universe around us appears to be expanding. For example, the Earth doesn't seem to be getting any farther away from the Sun. The Sun is not getting any farther away from our galaxy. Thank about smaller scales, like your body; your body (luckily) is not expanding along with the universe. And the reason is that the expansion of the universe is actually a pretty gentle force; you really only notice it out in the middle of nowhere in the vast reaches of space between the galaxies. There's a lot of space out of there, so there is a lot of space to expand and so you really notice this expansion. But there are things that are stronger than the expansion force. For example, my body is held together by chemical forces and by electrical forces. That is much, much stronger than the tiny little push that space has to expand inside me. I hold together very well. One of the analogies I think about is: You could try to push over the Empire State Building by blowing on it. You are actually exerting a force on the Empire State Building by blowing on it, you can measure that force, but you're not going to blow over the Empire State Building. There are things that are much stronger than this omnipresent but gentle force of the expansion of the universe. The gravity between the Sun and the Earth is stronger than space's pressure to expand over that scale. The force of gravity is stronger than the outward push of the expansion of the universe. That's also true of the galaxy, we are held in orbit around the center of the galaxy. Gravitationally, that's much stronger than any expansion force...

The Hubble Space Telescope discovered a new nearby galaxy while searching for white dwarf stars in a nearby globular cluster. The new galaxy, called Bedin I, was spotted hiding behind the globular cluster NGC 6752. This new galaxy is tiny, only 3000 light years wide, and classified as a dwarf spheroidal galaxy. These dwarf galaxies are the building blocks of much larger galaxies like our Milky Way, so studying them tells us a lot of about how the universe formed and evolved over time. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/yn3WWVzpT_E 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

In 2012, scientists detected the most distant galaxy discovered to date. This galaxy is now expected to be over 46 billion light years from the Earth, at the very edge of the observable universe. But what differentiates the observable universe and the rest of the universe? In this video, we examine how a 13 billion year old universe can be hundreds of billions of light years in diameter, and what might be waiting for us behind the barrier of the cosmic horizon.

At the centre of every galaxy, there is a supermassive black hole (a million to a billion times bigger than the Sun). But how do we even know that? There are so many scientific results that have jigsaw-pieced together throughout the past century that allow us to know that now, so join me, as I go through decade by decade and explain the significance of all the results that have built up the big picture.

The Hubble Space Telescope created a giant mosaic image of the Triangulum Galaxy (M33) at the 233rd meeting of the American Astronomical Society. It's the highest-resolution image of Triangulum galaxy ever created, resolving more than 15 million individual stars. Triangulum is the third-largest galaxy in the Local Group of galaxies, which include the Andromeda galaxy, the Milky Way galaxy, and about 50 dwarf galaxies. Hubble made a similar mosaic of the Andromeda galaxy in 2015. These Hubble mosaics, combined with similar studies of the Milky Way and Magellanic Clouds, will allow astronomers to better understand stellar evolution both locally and throughout the universe. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 Share this video with a fellow space traveler: https://youtu.be/8h_QZN6bxrc 🔴 Watch my most recent upload: https://youtu.be/kCpqlLeGSS4 🚀 Join the Launch Pad community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you.

All galaxies are not the same. Some are elliptically shaped; others pinwheel shaped. Many change over time, including our Milky Way, which is gobbling up nearby dwarf galaxies.

What the *fork* is going on in this galaxy?! It looks amazing but we still don't have an accepted theory for explaining how these rings form. Let me take you through a couple of our best ideas. And whoops, had a brain typo halfway through this video. Hoag's object dimensions should be 17 thousand light years, 75 thousand light years and 125 thousand light years.

Our perspective from Earth could be distorting our understanding of space. Here’s what you need to know about the theory of AGN unification. What Really Happens When Galaxies Collide - https://youtu.be/eWqETkudZXo Read More: Why It’s Hard to Recognize a Black Hole http://nautil.us/blog/why-its-hard-to-recognize-a-black-hole “If they are all fueled by supermassive black holes, why don’t all AGN look the same? One reason could be our point of view. The theory of AGN unification posits that all AGN have the same basic building blocks (accretion disk, jets, torus); The striking differences we observe, according to this theory, are all due to their orientation in space.” Active Galaxies https://imagine.gsfc.nasa.gov/science/objects/active_galaxies1.html “Active galaxies are galaxies that have a small core of emission embedded at the center of an otherwise typical galaxy. This core is typically highly variable and very bright compared to the rest of the galaxy.” What are active galactic nuclei? https://phys.org/news/2016-11-galactic-nuclei.html “In the 1970s, astronomers became aware of a compact radio source at the center of the Milky Way Galaxy – which they named Sagittarius A. After many decades of observation and mounting evidence, it was theorized that the source of these radio emissions was in fact a supermassive black hole (SMBH).” ____________________ Elements is more than just a science show.

Dr. Claire Max (University of California Observatories) Oct. 3, 2018 When light from space enters Earth’s atmosphere, it is distorted and displaced, something our eyes perceive as “twinkling.” Adaptive optics can remove a great deal of this distortion, essentially restoring much of the detail we’ve been robbed off in our view of the star and galaxies. Dr. Max, a world-renowned pioneer in this technique, shows us how modern lasers allow her to do this very precisely. And she discusses how this technique is giving us sharper views of such cosmic events as the collision of nearby galaxies.

The Sombrero Galaxy has a distinctive ring of dust that circles a smooth bulge of stars. The galaxy's dust and inner flat disk are very clear in the infrared. The Sombrero Galaxy may be a spiral galaxy like the Milky Way, but because of its extremely edge-on orientation, we see it in the flat pancake aspect. Our Milky Way would also have this appearance if viewed from the side angle. Optical: The dust ring is partially hidden in the galaxy's visible-light glow. Infrared: The galaxy's dust and inner flat disk are clear when viewing infrared. ABOUT THE INFRARED UNIVERSE COLLECTION The human eye can only see visible light, but objects give off a variety of wavelengths of light. To see an object as it truly exists, we would ideally look at its appearance through the full range of the electromagnetic spectrum. Telescopes show us objects as they appear emitting different energies of light, with each wavelength conveying unique information about the object. The Webb Space Telescope will study infrared light from celestial objects with much greater clarity and sensitivity than ever before. Explore the Infrared Universe.

Messier 82 (M82), or the Cigar Galaxy, is an edge-on spiral undergoing a massive burst of star formation in its core. Many thousands of stars, and their surrounding gas and dust, have been stirred up. These stars are expelling violent winds that are blowing gas and dust out of the galaxy. The only hint of this in visible light are fountains of hot hydrogen gas streaming out of its disk. In infrared, the burst becomes clearer as we see massive amounts of dust also blowing out of the center. Optical: In visible light the edge-on disk highlights the geysers of hot gas shooting out of M82's core. Infrared: Infrared light lets us see this galaxy's full disk of stars and reveals volumes of dust (shown in red) carried along with the hot gas. X-ray: Chandra's X-ray image reveals gas that has been heated to millions of degrees by the violent outflow.

Astronomers have used data from NASA's Chandra X-ray Observatory to capture a dramatic image of an enormous tail of hot gas. This tail stretches for more than a million light years behind a group of galaxies that is falling into the depths of an even-larger cluster of galaxies. Discoveries like this help astronomers learn about the environment and conditions under which the Universe's biggest structures evolve. Galaxy clusters are the largest structures in the Universe held together by gravity. While galaxy clusters can contain hundreds or even thousands of individual galaxies, the lion's share of mass in a galaxy cluster comes from hot gas, which gives off X-rays, and unseen dark matter. How did these cosmic giants get to be so big? Scientists have discovered that one way galaxy clusters grow is by capturing other galaxies with their extraordinarily powerful gravity. Abell 2142 is a galaxy cluster that contains hundreds of galaxies immersed in giant reservoirs of multi-million-degree gas. A wide-field view including Chandra data shows that a much smaller group of galaxies is plummeting toward the center of Abell 2142, adding to the enormous heft of this cluster. Behind this diving galaxy group, astronomers found a remarkable long tail of X-rays that extends for hundreds of thousands of light years. This tail formed when hot gas from the group of galaxies falls is stripped off into Abell 2142, much like leaves from a tree in the fall during a strong gust of wind. The shape and length of the tail tells astronomers about certain properties in the system, such as the strength of the magnetic fields that may be wrapping about the tail. Galaxy clusters have been one of Chandra's most compelling targets over its nearly two decades of operations in space. Scientists look forward to studying many more in the years to come.

Astronomers have used data from NASA's Chandra X-ray Observatory to make heads and tails of a fascinating galactic system. Abell 2142 is a galaxy cluster, one of the largest structures in the Universe, containing hundreds of galaxies and huge amounts of hot gas. Chandra captured a smaller galaxy group, with a handful of galaxies, plummeting toward Abell 2142. Behind this diving galaxy group is a long tail of X-rays extending for over a million light years. By studying this system, astronomers can learn more about how the Universe's biggest objects have collided and grown over billions of years.

According to a report by Geek.com, physicists have uncovered some of the very first galaxies that formed in our universe. Using data collected from the Institute for Computational Cosmology at Durham University and Harvard-Smithsonian Center for Astrophysics suggest that a number of known galaxies are over 13 billion years old. Carlos Frenk, director of Durham University’s ICC, said in a statement, “Finding some of the very first galaxies that formed in our Universe orbiting the Milky Way’s own backyard is the astronomical equivalent of finding the remains of the first humans that inhabited the Earth." https://www.geek.com/news/oldest-ever-galaxies-discovered-outside-milky-way-1749525/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
