GALAXIES

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

Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! 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 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.

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.

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.

The new findings support the idea of galactic cannibalism in which big galaxies grow bigger by merging or consuming smaller galaxies. *All systems go for Falcon heavy Space X is about to launch its largest and most powerful rocket ever -- the Falcon Heavy. The new 70 metre tall launch vehicle combines three Falcon 9 core stages mounted side by side. Instead of the usual dummy payload packed with scientific monitoring equipment – SpaceX boss Elon Musk is sending his own midnight cherry Tesla Roadster with David Bowie’s Space Oddity playing through the speakers. *Scientists discover how black holes regulate star formation in massive galaxies For year astronomers have noticed a direct relationship between the size of a galaxy and the mass of the supermassive black hole at its centre -- But the machinations of how it all worked has been more of a mystery. Now a new study has provided direct observational evidence that the mass of the central black hole affects the formation of new stars throughout the galaxy’s lifetime. *The Science Report The biological markers in blood plasma which could provide an early warning of Alzheimer’s disease.

Astrophysicists at the University of Oklahoma, using a technique called microlensing, have confirmed the existence of exoplanets beyond our own Milky Way galaxy. The scientific team has discovered not just one or two, but an estimated multitude of planets which range in size form the Moon to Jupiter. OU professor Xinyu Dai said, "We are very excited about this discovery. This is the first time anyone has discovered planets outside our galaxy. These small planets are the best candidate for the signature we observed in this study using the microlensing technique.” OU researcher Eduardo Guerras said, "This is an example of how powerful the techniques of analysis of extragalactic microlensing can be." https://www.digitaltrends.com/cool-tech/scientists-discover-exoplanets-beyond-milky-way-galaxy/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

NASA scientists revealed a new image taken by the Hubble Space Telescope showing one of the oldest galaxies ever discovered in unprecedented detail.

Stream on demand from www.bitesz.com (mobile friendly). SpaceTime 20180105 Series 21 Episode 02 *Solving the mystery of what came first? Astronomers may be a step closer to solving one of the greatest mysteries in astrophysics – which came first the galaxy – or the supermassive black hole at its centre. The problem is do galaxies form first from the accumulation of stars, globular clusters, and molecular gas and dust clouds -- with densities at the galactic centre eventually becoming so high it forms a black hole. *Supermassive black hole stellar factory Astronomers have discovered 11 newly formed infant protostars within three light years of the supermassive black hole at the centre of our galaxy. Black holes generate powerful gravitational tidal forces and intense ultraviolet and X-ray radiation – environments far more conducive to destroying stars rather than creating them. *Mars may not be as dry as it seems A new study suggests water on Mars is being absorbed by the red planet’s rocks like a sponge. The findings reported in the journal Nature suggest that Martian basalt rocks can hold up to 25 percent more water than similar basalts on Earth. *SpaceX to launch Falcon Heavy shortly After more than 12 years of planning and development Space X is finally getting ready to fly its new Falcon Heavy launch vehicle. The 70-metre-tall reusable rocket is based around three Falcon 9 common booster core stages -- mounted side by side in a similar fashion to the Delta 4 heavy -- from which it will take the title as the world’s most powerful operational launch vehicle.

Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the Universe. These ‘newborns’ – observed as they appeared nearly 13 billion years ago – spun like a whirlpool, similar to our own Milky Way. An international team used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to open a new window onto the distant Universe, and have for the first time been able to identify normal star-forming galaxies at a very early stage in cosmic history with this telescope. Light from distant objects takes time to reach Earth, so observing objects that are billions of light years away enables us to look back in time and directly observe the formation of the earliest galaxies. The Universe at that time, however, was filled with an obscuring ‘haze’ of neutral hydrogen gas, which makes it difficult to see the formation of the very first galaxies with optical telescopes. Astronomers used ALMA to observe two small newborn galaxies, as they existed just 800 million years after the Big Bang. By analyzing the spectral ‘fingerprint’ of the far-infrared light collected by ALMA, they were able to establish the distance to the galaxies and, for the first time, see the internal motion of the gas that fueled their growth. The researchers found that the gas in these newborn galaxies swirled and rotated in a whirlpool motion, similar to our own galaxy and other, more mature galaxies much later in the Universe’s history. Despite their relatively small size – about five times smaller than the Milky Way – these galaxies were forming stars at a higher rate than other young galaxies, but the researchers were surprised to discover that the galaxies were not as chaotic as expected. The data from this project on small galaxies paves the way for larger studies of galaxies during the first billion years of cosmic time.

As many of you know who’ve been following SFN for a while know that this video series was started in January 2011 during the winter meeting of the American Astronomical Society. Well this week finished the one for 2018 and here is a roundup of stories I found most interesting. The people with the American Astronomical Society call their winter meeting the Superbowl of Astronomy and while that may be a bit hyperbolic, it is an exciting time for astronomers. They get to announce some of their most exciting work during this meeting and while I have been to several, lately I’ve had to watch them from afar. But I do hope to start live streaming from them again one day. So in the spirit of SFN, I’m going to give you a brief roundup of some of the latest research that came out this week from the world of professional astronomers from around the world. There was so much released this week that there is no way I can cover all of it in a 10 minute or so video, so I’m keeping it to those things I found most interesting.

A new visualization provides an exceptional virtual trip — complete with a 360-degree view — to the center of our home galaxy, the Milky Way.

The Earth is located about 26,000 light years, or about 200,000 trillion miles, from the center of the Galaxy. While humans cannot physically travel there, scientists have been able to study this region by using data from powerful telescopes. A new visualization, based on data from NASA's Chandra X-ray Observatory and other telescopes, lets viewers explore the Milky Way's center. In this 360-degree movie, viewers can see powerful winds from giant stars around the Galaxy's supermassive black hole. Scientists are using this visualization to examine the effects from the black hole on its stellar neighbors.

A 360-degree movie immerses viewers into a simulation of the center of our Galaxy. This visualization was enabled by data from Chandra and other telescopes and allows viewers to control their own exploration of this region. From the vantage point of the Milky Way's supermassive black hole, Sgr A*, the viewer can see about 25 Wolf-Rayet stars (white, twinkling objects) as they continuously eject stellar winds (black to red to yellow color scale). These winds collide with each other, and then some of this material (yellow blobs) spirals towards Sgr A*. The movie shows two simulations, each of which start around 350 years in the past and span 500 years. The first simulation shows Sgr A* in a calm state, while the second contains a more violent Sgr A* that is expelling its own material, thereby turning off the accretion of clumped material (yellow blobs) that is so prominent in the first portion.

The hubble space telescope recently captured beautiful images of galaxy NGC 5256, which they have named Markarian 266. According to mnn.com, "The bright colors radiating from the center are actually two galaxies on the verge of a massive galactic collision... New technological advancements in imagery made it possible to show the presence of gas." Fans of beautiful space imagery should definitely check it out. https://www.mnn.com/earth-matters/space/videos/hubble-telescope-captures-stunning-galactic-collision http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
