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.

NASA recently shared details of massive bubbles that our galaxy is blowing.

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

According to a report by Geek.com, a new discovery by researchers at the University of Michigan has uncovered our Milky Way galaxy's long-lost, and long-dead, stellar sibling. The new study shows that our nearest galactic neighbor, the Andromeda galaxy, cannibalized another massive galaxy two billion years ago. "A rich trail of evidence" left behind after the galaxy, named M32p, was devoured has helped scientists understand how disk galaxies like the Milky Way evolve and survive. It turns out the consumed galaxy was at least 20 times larger than any galaxy that ever merged with the Milky Way, and had been the third-largest member of the so-called Local Group. https://www.geek.com/news/scientists-shocked-to-discover-milky-ways-long-lost-sibling-1747200/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

According to a new study published Monday in the journal Nature Astronomy, two billion years ago, our Milky Way galaxy's sibling, known as M32p, was violently cannibalized by our closest and largest galactic neighbor, Andromeda. CNN reports that the large neighboring galaxy is expected to have consumed hundreds of surrounding smaller galaxies. Before being consumed, the M32p galaxy was reportedly the third largest galaxy behind Andromeda and the Milky Way and was at least 20 times larger than any galaxy that ever merged with the Milky Way. Both evidence and computer simulations allowed researchers to reconstruct the events leading up to galaxy M32p's demise approximately 2 billion years ago. https://www.cnn.com/2018/07/23/world/milky-way-galaxy-sibling-m32/index.html http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The Milky Way has gobbled up dozens of dwarf galaxies and added them to its structure. Today we're going to look at the ongoing hunt for the wreckage of past mergers. And what we've discovered about dwarf galaxies in general.

This animation shows the Messier 101 (Pinwheel) Galaxy, with simulated rotation, in visible, then infrared, then X-ray, and finally all three combined. M101 is a comparable in size to the Milky Way. The disk is 100 billion solar masses, and the central bulge of about 3 billion solar masses. M101 is rich is pinkish star forming regions, many of which are very large and bright. Unlike most spiral galaxies, M101spiral shape is notably asymmetrical. This is due to the tidal forces from interactions with its companion galaxies. These gravitational interactions compress interstellar hydrogen gas, which then triggers strong star formation activity in M101's spiral arms. Video Credit: NASA, ESA, and G.

Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the Universe and the most distant galaxy ever observed by ALMA or the VLT. The video is available in 4K UHD.

Astronomers think that our Sun was born in a cluster of stars about 4.6 billion years ago that quickly dispersed. Studying other stellar clusters helps scientists better understand how stars — including our Sun — are born. NGC 6231 is a relatively nearby cluster in the Milky Way galaxy with thousands of stars. NASA's Chandra X-ray Observatory has been used to identify the young Sun-like stars in NGC 6231, which have, until recently, been hiding in plain sight. By combining X-rays from Chandra with infrared data, astronomers have compiled the best census to date of the stars in NGC 6231.

Fermi bubbles are made up of gamma rays, but where they came from is still up for debate. Did they come from a star-forming region, or the black hole at the middle of our galaxy?

Astronomers are sharing details of a cosmic megamerger involving multiple galaxies.

NGC 2207 is a pair of colliding spiral galaxies. Their bright central nuclei resemble a striking set of eyes. In visible light, trails of stars and gas trace out spiral arms, stretched by the tidal pull between the galaxies. When seen in infrared light (IR), the glow of warm dust appears. This dust is the raw material for the creation of new stars and planets. Complementary to the IR, the X-ray view reveals areas of active star formation and the birth of super star clusters. Though individual stars are too far apart to collide, the material between the stars merges to create high-density pockets of gas. These regions gravitationally collapse to trigger a firestorm of starbirth. The galaxy collision will go on for several millions of years, leaving the galaxies completely altered in terms of their shapes. Video Credit: NASA, ESA, and G.

Astronomers have used NASA's Chandra X-ray Observatory to study a gigantic and resilient "cold front" in the Perseus galaxy cluster. This cold front consists of a band of gas with a "cool" temperature of about 30 million degrees moving through lower density, 80-million-degree gas. Scientists determined this cold front spans about 2 million light years, moves at speeds around 300,000 mph, and formed some 5 billion years ago. Not only has it survived for so long, the cold front has also remained surprisingly sharp and split into two different pieces. This suggests that magnetic fields are wrapped around the cold front, which formed before the birth of our Solar System, preserving it.

Dark Matter has been a persistent thorn in the side of physicists. It shouldn’t be there, but it has to be, and obviously is. And, even weirder, dark matter is far more common […] The post We just Discovered A Galaxy Without Dark Matter, Proving it Exists appeared first on Geek.com. https://www.geek.com/science/we-just-discovered-a-galaxy-without-dark-matter-proving-it-exists-1735431/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The one just left of the Milky Way center in the constellation of Andromeda. That’s M31 – the Andromeda galaxy. It’s two and a half million light years away and host to a trillion stars. It has a beautiful spiral structure spanning its gently rotating disk 220 thousand light years in diameter, and a central bulge that hides a giant black hole that contains the mass of well over a hundred million Suns. Andromeda is also racing towards our galaxy at 110 km/s.

Like this content? Please consider becoming a patron: https://patreon.com/DeepAstronomy Even though it is relatively nearby at 300 million light years from Earth, the galaxy, named Dragonfly 44, had been missed by astronomers for decades because it is very dim. The discovery of this dim object heralds in a new class of galaxies that have become known as ‘dark galaxies’ or ‘ultra diffuse galaxies’ because they contain relatively few stars, yet have a mass equal to our own Milky Way with hundreds of billions of stars. It was only discovered recently, in 2015, when the Dragonfly Telephoto Array, then a small collection of 24 commercially available 400mm telephoto lenses, looked towards a region of sky in the constellation Coma. But as astronomers looked closer using larger telescopes with specialized instruments, they realized this dim, tiny galaxy was more than meets the eye - literally. It contained so few stars. There were so few stars in this galaxy that there was no way they could all stay together as a gravitationally bound object - they would simply fly apart. So what was keeping the stars in Dragonfly 44 together? Astronomers had pretty good idea: dark matter. Dragonfly 44 image Pieter van Dokkum / Roberto Abraham / Gemini Observatory / SDSS / AURA.

This video pans over NASA/ESA Hubble Space Telescope observations of the spiral galaxy NGC 3344 that lies about 20 million light-years away. The galaxy is seen face-on, allowing us to see its spiral arms and the bright core. Because of the many filters used to create this image — ranging from the ultraviolet to the near-infrared — the bright young stars glowing blue and the red regions of dense gas and dust are visible.

Our eyes detect only visible light, but on board Hubble are a variety of instruments that together detect many different wavelengths of light. This means that Hubble is able to observe galaxies over a wide range of wavelengths to reveal features that would otherwise remain invisible to our eyes.
