GALAXIES

The region around the Galactic Center contains a well-characterized excess of gamma rays, which has garnered great interest as a possible signal of either dark matter particles colliding and annihilating, or a previously undiscovered population of pulsars in the stellar bulge. Analyses of the photon statistics of this excess have been used to argue that the pulsar interpretation is strongly favored -- however, I will present recent work arguing that it may be premature to exclude a dark matter origin for the excess on these grounds. I will outline the history of our understanding of the excess and the arguments for various interpretations, describe the current status of the controversy, and discuss future paths forward

Senior Scientist Seth Shostak talks about the strange behavior of certain galaxies. Are they somehow connected to one another?

Fly across the local galactic neighborhood to the Triangulum galaxy (M33), a smaller spiral than our Milky Way galaxy. Zoom in first on one of M33's bright regions of star birth, nebula NGC 604, glowing with hot ionized hydrogen gas. The remarkable ability of NASA’s Hubble Space Telescope to resolve millions of individual stars is on display in this pan across M33's dense star field.

If you believe the world’s leading physicists, the vast majority of matter in the universe is hiding in plain sight. For nearly a century, evidence has mounted that the gravitational pull necessary to keep clusters of galaxies intact, as well as stars within galaxies from flying apart, requires far more matter than we can see—matter, according to the experts, that has eluded our telescopes, because it does not give off light. Problem is, such “dark matter” has also eluded one specially designed detector after another that researchers have deployed to catch it. Which raises the big question: What if we have failed to find dark matter because it isn’t there? Join leading physicists on a scientific treasure hunt that has proved more challenging than anyone expected, and may ultimately require rethinking some of our most fundamental ideas about the universe.

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)

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 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? Today, 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.

This video sequence gives a detailed close-up view of the Triangulum Galaxy, also known as Messier 33. The beautiful picture of this nearby spiral, the second-closest large galaxy to our own, was captured by the NASA/ESA Hubble Space Telescope. The image is packed with bright star clusters and clouds of gas and dust. This picture is the most detailed wide-field view of this object ever taken and shows the many glowing gas clouds in the spiral arms with particular clarity.
