BLACK HOLES

The image of M87's supermassive black hole released by the Event Horizon Telescope on April 10th 2019 is not just a pretty picture. Here I run down 5 reasons why we care about this result and what more it can help us understand. 1 - The first glimpse of an event horizon 00:30 2 - Testing General Relativity 03:43 3 - Testing how black holes grow 06:25 4 - Small scale = large scale 07:53 5 - Proof of concept 10:07 What Next? 13:40 Bloopers 15:46 Here are the academic journal papers released with the image (free access): https://iopscience.iop.org/journal/2041-8205/page/Focus_on_EHT My Direct Collapse Black Hole video: https://youtu.be/1-A2lpnbTMM Katie Bouman's TED talk on the computer algorithm used to produce the image: https://www.ted.com/talks/katie_bouman_what_does_a_black_hole_look_like?language=en My appearance on Channel 4 News (!): https://www.youtube.com/watch?v=Ga5YrqKGTY0 If you have questions you want me to answer either tweet them to me (https://twitter.com/drbecky_) or leave them in the comments below.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow. This 17-minute film explores the efforts that led to this historic image, from the science of Einstein and Schwarzschild to the struggles and successes of the EHT collaboration.

Scientists working on the Event Horizon Telescope project have produced an image of the "unseeable", capturing the world's fist picture of a black hole. It took nearly two years for 200 researchers and a network of eight radio telescopes spanning the globe to make the breakthrough, which was previously thought impossible.

An international team of scientists used the Event Horizon Telescope to obtain the first image of a black hole. They say the image of the center of the galaxy M87 shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the sun. Watch the announcement.

Astronomers from the Event Horizon Telescope Collaboration have taken the first ever image of a black hole - at the heart of the galaxy M87. Read more in Nature's news story: https://www.nature.com/articles/d41586-019-01155-0 #realblackhole #EHTblackhole

#FirstPictureofBlackHole #FirstImageofBlackHole #EventHorizonTelescope The first image of a black hole will be public today during a global press meet that will be held from 6:45 PM - 7:45 PM (Nepali Time), Wednesday, April 10, 2019, by the Event Horizon Telescope (EHT) team and its collaborator around the globe. The image would be a groundbreaking achievement for the two-year-old international observatory. The hundreds of millions of black holes that pepper the universe shape our very existence, which we know thanks to recent research. Discoveries made in the last three years revealed that when black holes collide they can send literal shockwaves across galaxies, moving every piece of matter that surrounds us.

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes? Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough. This was a really fun speculative question to think about, especially because it ties in with my PhD thesis too. Let me know if you want me to do a video describing my thesis down in the comments. Both my lapel microphones ran out of battery this week. Thankfully one of them didn't need a battery to use with a smartphone, so the sound was recorded that way. It's not brilliant I know, but it'll do. My research schedule this week stopped me from delaying filming until I could get a battery. The sound suffered so science wouldn't.

The first detection of colliding black holes rocked the scientific world, establishing that gravitational waves are real and that we are able to measure them. More recently, scientists have achieved the first detection of colliding neutron stars, rocking the scientific world again and inaugurating the era of multi-messenger gravitational wave astronomy. In this program, astronomers and astrophysicists discuss the implications of these colossal cosmic mergers, what they create, and how they’re changing our view of the universe.

Earnest C. Watson Lecture and Robert F. Christy Lecture by Professor Kip S. Thorne, "My Romance with Caltech and with Black Holes, Wormholes, Time Travel, and Gravitational Waves." The "warped side of the universe" - objects and phenomena made from warped space and time - was once mere speculation. In this talk, Caltech physicist Kip Thorne (BS '62), will describe how he and colleagues transformed a portion of that warped side (black holes and gravitational waves) into observed phenomena, and what they have learned about another portion (wormholes and time travel). Kip S. Thorne is the Richard P. Feyman Professor of Theoretical Physics at Caltech in the Division of Physics, Mathematics and Astronomy and a 2017 Nobel Laureate. Learn more about: - Kip S.

In this talk Dr. Meg Urry of Yale University talks about Black Hole formation and the effect on galaxies. She presented at WAS on February 19, 2019.

Science fiction films have long depicted black holes as portals through space and time or gateways to other dimensions. And now, physicists have found that black holes might be suitable for hyperspace travel after all. Following is a transcript of the video: Black holes skirt the line between science fiction and science fact. On the one hand, scientists have seen real black holes in action, consuming unsuspecting stars that pass too close. But where reality ends and fiction takes over is at the edge of a black hole – a place called the event horizon, where no spacecraft has ever gone. So, whatever happens beyond that boundary, inside of a black hole, is anyone’s guess. Scientists agree that if you travel far enough into a black hole, gravity will eventually become so strong that it kills anything in its path. But sci-fi films are more optimistic, depicting black holes as portals through space and time or gateways to other dimensions. And it turns out, some scientists now think the sci-fi buffs may be onto something. Black holes might be suitable for hyperspace travel, after all; it just takes the right kind of black hole. At the center of every black hole is a point of infinite density, called a singularity. It’s what gives black holes their strong gravitational pull. And for decades, scientists thought singularities were all the same, so anything that passed the event horizon would be destroyed the same way: by being stretched and pulled like an infinitely long piece of spaghetti. But that all changed in the early 1990s when different research teams in Canada and the US discovered a second singularity called a “mass inflation singularity.” It still has a strong gravitational pull, but it would only stretch you by a finite amount, and potentially NOT kill you in the process, meaning, you might survive the trip through a black hole. More specifically, through a large, rotating black hole, which is where these types of singularities exist. Now, astronomers obviously can’t travel through a black hole yet to test this theory. In fact, the best place to test this is at the supermassive black hole in the center of our home galaxy, the Milky Way, which is 27,000 light years away. Not conveniently close to the least. Therefore, scientists instead run computer simulations to see what would happen if we did manage to reach an isolated, rotating black hole, and now, for the first time, a team of scientists at UMass Dartmouth and Georgia Gwinnett College has done exactly that. Lior Burko: “You would feel a slight increase in temperature, but it would not be a dramatic increase. It’s just that you don’t have enough time to respond to the very strong forces. It would just go through you too quickly.” He added that passing through a weak singularity is like quickly running your finger through a candle flame that’s 1,000 degrees Celsius. If you hold your finger in the flame long enough, you’ll get burned, but pass your finger through quickly, and you’ll barely feel a thing. Similarly, if you pass through a weak singularity with the right speed and momentum, and at the right time, you may not feel much at all. As for what happens once you get through to the other side, no one really knows, but Burko has his own ideas. He says one possibility is that we’d arrive at some other remote part of our galaxy, potentially light years away from any planets or stars, but a second, and perhaps more intriguing, a possibility is that we’d arrive in a different galaxy altogether. That's if you even make it that far. Scientists say more research is needed before we’re anywhere close to successfully traveling through a black hole. But when we are ready, one of the safest passageways might be the supermassive black hole at the center of our galaxy called Sagittarius A*, and it might just be our ticket out of the Milky Way. ------------------------------------------------------ #BlackHole #Space #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

Most sources talk about Schwarzschild black holes, but those don't spin. Most are what we call Kerr black holes, or rotating black holes, surrounded by a region called an ergosphere. The spacetime around them is not only stretched, but also twisted, leading to some strange phenomena. ________________________________ VIDEO ANNOTATIONS/CARDS Black Hole Playlist: https://www.youtube.com/playlist?list=PLOVL_fPox2K-zpTeryROTkmzzsMssSMWp What is Electric Charge? https://youtu.be/gvX29HPmBEI The Ultimate Guide to Relativity: https://youtu.be/FdWMM6aXpYE ________________________________ RELATED YOUTUBE VIDEOS Veritasium on Spinning Black Holes: https://youtu.be/fu3645D4ZlI Kurzgesagt on Spinning Black Holes: https://youtu.be/ulCdoCfw-bY Fraser Cain on Spinning Black Holes: https://youtu.be/SMrwHnow3hk ________________________________ SUPPORT THE SCIENCE ASYLUM Patreon: http://www.patreon.com/ScienceAsylum Advanced Theoretical Physics (eBook): https://gumroad.com/l/ubSc Merchandise: http://shop.spreadshirt.com/scienceasylum/ ________________________________ HUGE THANK YOU TO THESE PATRONS Einsteinium Crazies: LT Marshall Faulds, Kenny Holmes, Ilya Yashin, Rick Finn Plutonium Crazies: Anamnesia, JKLMN Anderson, Timothy Blahout, Drake Dragon, Kevin MacLean Platinum Crazies: Vittorio Monaco, Al Davis, Stephen Blinn, Mikayla Eckel Cifrese, Evgeny Ivanov ________________________________ OTHER SOURCES http://simbad.u-strasbg.fr/simbad/sim-id?Ident=NAME+Sgr+A* https://arxiv.org/abs/1410.2130 http://notizblock.yukterez.net/viewtopic.php?p=225/ http://www.madore.org/~david/math/kerr.html https://www.nature.com/news/spin-rate-of-black-holes-pinned-down-1.13512 https://www.nasa.gov/mission_pages/nustar/multimedia/pia16696.html http://www.astro.ucla.edu/~ghezgroup/gc/journey/smbh.html ________________________________ LINKS TO COMMENTS https://www.youtube.com/watch?v=C7tQJ42nGno&lc=UgzASerpKIUtyprIaKd4AaABAg ________________________________ IMAGE CREDITS Supermassive Black Hole: https://www.eso.org/public/videos/eso1835c/ Black Hole Eating: https://svs.gsfc.nasa.gov/12005 #blackholes #astronomy #generalrelativity

January 23, 2019 Dr. Alex Filippenko (University of California, Berkeley) reviews his fascinating research career in astronomy, focusing on his work with black holes and with active galaxies and supernovae (exploding stars) -- and their role in helping us determine the ultimate fate of the universe. He also talks about some of the circumstances and people that influenced his work as a scientist, about the importance of education and outreach for the public support of science, and about his work to help ensure the future of Lick Observatory, the first permanently occupied mountain-top observatory in the world.

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station. NICER detected X-ray light from a recently discovered black hole, called MAXI J1820+070 (J1820 for short), as it consumed material from a companion star. Waves of X-rays formed "light echoes" that reflected off the swirling gas near the black hole and revealed changes in the environment's size and shape. A black hole can siphon gas from a nearby star and into a ring of material called an accretion disk that glows in X-rays. Above this disk is the corona, a region of subatomic particles that glows in higher-energy X-rays. Astrophysicists want to better understand how the inner edge of the accretion disk and the corona change in size and shape as a black hole accretes material from its companion star. If they can understand how and why these changes occur in stellar-mass black holes over a period of weeks, they could shed light on how supermassive black holes evolve over millions of years and how they affect the galaxies in which they reside. One method used to chart those changes is called X-ray reverberation mapping, which uses X-ray reflections in much the same way sonar uses sound waves to map undersea terrain. From 10,000 light-years away, the scientists estimated that the corona contracted vertically from roughly 100 to 10 miles -- that's like seeing something the size of a blueberry shrink to something the size of a poppy seed at the distance of Pluto.

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?

A ricocheting jet blasting from a giant black hole has been captured by NASA's Chandra X-ray Observatory. Chandra's data reveal the presence of a powerful jet of particles and electromagnetic energy that has shot out from the black hole and slammed into a wall of hot gas, then ricocheted to punch a hole in a cloud of energetic particles, before it collides with another part of the gas wall. Cygnus A is a large galaxy that sits in the middle of a cluster of galaxies about 760 million light years from Earth. A supermassive black hole at the center of Cygnus A is rapidly growing as it pulls material swirling around it into its gravitational grasp. During this process, some of this material is redirected away from the black hole in the form of a narrow beam, or jet. Such jets can significantly affect how the galaxy and its surroundings evolve. In a deep observation that lasted 23 days, scientists used Chandra to create a highly detailed map of both the jet and the intergalactic gas, which they used to track the path of the jets from the black hole. The jet expanded after ricocheting and created a hole in a nearby cloud of particles that is between 50,000 and 100,000 light years deep and 26,000 light years wide. For context, the Earth is located about 26,000 light years away from the center of the Milky Way galaxy. Energy produced by jets from black holes can heat intergalactic gas in galaxy clusters and prevent it from cooling and forming large numbers of stars in a central galaxy like Cygnus A. By studying Cygnus A, scientists can tell more about how jets from black holes interact with their surroundings.

In a galaxy about 290 million light years from Earth, a star wandered too close to a black hole. The immense gravitational forces of the black hole shredded the star, sending the stellar remains into orbit around it. Scientists used several telescopes including NASA's Chandra X-ray Observatory to study this "tidal disruption" event called ASASSN-14li. They were able to use the data to measure the spin of the giant black hole at the center of the galaxy containing ASASSN-14li. The scientists determined that the black hole in ASASSN-14li is spinning incredibly quickly — about half as fast as the speed of light or faster. Since the spins of black holes have been difficult to measure, this discovery is exciting for astronomers.

In November 2014, a network of optical telescopes picked up a bright outburst from a galaxy about 290 million light years from Earth. Scientists determined that this was a so-called tidal disruption event, where a star wandered too close to a black hole and was ripped apart by immense gravitational forces. Astronomers used other telescopes including a flotilla of high-energy telescopes in space — NASA's Chandra X-ray Observatory, ESA's XMM-Newton and NASA's Neil Gehrels Swift observatory — to study the X-rays emitted as the remains of a star swirled toward the black hole at the center of the galaxy. Some of the remains of the star are pulled into a disk where they circle the black hole before passing over the "event horizon," the boundary beyond which nothing, including light, can escape. The tidal disruption in ASASSN-14li allowed astronomers to estimate the spin rate of the black hole. A black hole has two fundamental properties: mass and spin. While it has been relatively easy for astronomers to determine the mass of black holes, it has been much more difficult to get accurate measurements of their spins. This debris from the shredded star gave astronomers an avenue to directly estimate the black hole's spin in ASASSN-14li. They found that the event horizon around this black hole is about 300 times the diameter of the Earth, yet rotates once every two minutes (compared to the 24 hours it takes to complete one rotation). This means that the black hole is spinning at least about half as fast as the speed of light. These results will likely encourage astronomers to observe future tidal disruption events for long durations to look for similar, regular variations in their X-ray brightness.

Black holes are notorious for pulling things toward them. But in some cases, black holes can act as powerful engines to blast material away. One of those black holes is found in Cygnus A, a large galaxy embedded within in a cluster of galaxies. Cygnus A's black hole is blasting a jet — a tightly-wound column of material — away from it at extremely high speeds. Astronomers found that his jet ricocheted off a wall of hot gas, then punched a hole in a cloud of energetic particles, leaving behind a gigantic hole. By studying this kind of behavior, scientists can better understand how black holes affect their surroundings. Only an X-ray telescope with the sharp vision of NASA's Chandra X-ray Observatory could make such a discovery.

Another episode of Night Sky News for this month - the first half what you can see in the sky this next month and the second half a recap of the space news of the last month. Tune in for how to catch Mercury, Venus and Jupiter in the early morning sky, a chance to see the Moon pass through M44 and how to catch the Quadrantis Meteor Shower on January 4th. In this episode I chat about the successful landing of the Mars Insight probe, the arrival of OSIRIS-REx at Bennu, the exit of Voyager 2 from the Solar System and four new gravitational wave detections of a black hole-black hole merger from LIGO. Here's the link to check when the International Space Station will be passing over your home town: https://spotthestation.nasa.gov/sightings/index.cfm Paper with announcement of four new gravitational wave detections: https://arxiv.org/pdf/1811.12907.pdf EDIT: So the audio isn't great in this one, but I do already own a lav mic. It was just muffled against the big Christmas jumper in this one. I did my best to remove the noise with free audio edit software. Please remember I'm not a professional videographer. This isn't my day job. I do this for fun and along with the editing I don't have time to reshoot if something isn't perfect - otherwise my research suffers for it. I'll get better with time as I get more familiar with the tech. Just bear with me while I get up to speed. Until then, let's not sacrifice cool science conversations for a few minor tech problems.
