Podcasts about black hole image

Charles Gammie is a professor at the University of Illinois at Urbana-Champaign. Born with an insatiable curiosity and a love for mathematics, Dr. Gammie's journey to the forefront of astrophysics was anything but ordinary. Despite initially having ambitions of becoming a lawyer, a serendipitous encounter with a wise advisor steered him toward statistics and physics. Little did he know, this fateful decision would set him on a path toward the cosmos, propelling him into the world of astrophysics and a PhD he never envisioned. Today, Dr. Gammie stands as a theoretical and computational astrophysicist whose research focuses on black holes, and the formation of stars, moons, and planets, where he has developed numerical methods for modeling relativistic plasmas, relativistic radiation magnetohydrodynamics, and radiative processes in hot plasmas. Notably, Dr. Gammie co-led the theoretical modeling efforts for the Event Horizon Telescope (ETH) project, enabling the interpretation of the EHT data and the groundbreaking first-ever image of a supermassive black hole at the center of the M87 galaxy. This unprecedented collaboration across continents and disciplines showcased human ingenuity and the pursuit of knowledge. In this conversation, Dr. Gammie shared profound insights into black holes, their mechanics, spinning nature, and implications for understanding time and space. He also explored existential topics like extraterrestrial life and reconciling science with religious beliefs, offering inspiring advice for young minds to embrace curiosity and the unconventional. From the origins of "black holes" to the nature of time itself, this conversation was a captivating odyssey through the cosmos, guided by a brilliant scientific mind. This is The UIUC Talkshow, and this is our conversation with Dr. Charles Gammie.

#243As we age our immune systems do too, making us less able to fight infections and more prone to chronic inflammation. But a team of scientists has been able to reverse these effects in mice, rejuvenating their immune systems by targeting their stem cells. But there's a long road to trying the same thing in humans.Have you seen the incredible new black hole image? Just a couple of years since the Event Horizon Telescope's first, fuzzy image of Sagittarius A* – the black hole at the centre of our galaxy – a new picture offers a closer look. The stunning image released this week features the spiralling lines of Sgr A*'s magnetic field, which is seeding new questions about how black holes behave.Millions of tonnes of unexploded ordnance litter the globe from conflicts both ongoing and long past. And as time passes these bombs are not getting any less dangerous – new research finds some are actually becoming more prone to exploding.Physicists have theorised that there is a particle called the graviton that carries the force of gravity – much like a photon carries light, or a gluon carries the strong nuclear force. But the graviton has so far remained elusive. Now, researchers think they've seen one, or at least a particle with the correct properties to be a graviton. How this experiment unfolded, and why even a possible sighting is exciting to theorists.Plus: How a bad night's sleep makes you feel older; why therapy horses get stressed when they don't have a choice; and a robot that can design, build and test paper planes.Hosts Christie Taylor and Sophie Bushwick discuss with guests Grace Wade, Alex Wilkins, Michael Le Page and Karmela Padavic-Callaghan.

Scientists have released a more detailed version of the first image of a black hole. That first image, released four years ago, showed a blurry, round-shaped orange object. Now, researchers have used machine learning methods to create an improved picture. The new image was recently published in the Astrophysical Journal Letters. The same shape remains as in the first image, but it has a narrower ring and sharper resolution. Scientists have said the black hole in the image sits at the center of a galaxy called M87, more than 53 million light-years from Earth. A light year is the distance light travels in a year --- about 9.5 trillion kilometers. The mass of the black hole is 6.5 billion times greater than that of Earth's sun.科学家们发布了第一张黑洞图像的更详细版本。四年前发布的第一张图片显示了一个模糊的圆形橙色物体。现在，研究人员已经使用机器学习方法来创建改进的图片。这张新图片最近发表在《天体物理学杂志快报》上。与第一张图片中的形状相同，但它的环更窄，分辨率更清晰。科学家们表示，图像中的黑洞位于一个名为 M87 的星系中心，距离地球超过 5300 万光年。一光年是光在一年内传播的距离——大约 9.5 万亿公里。黑洞的质量是地球太阳的 65 亿倍。A network of radio telescopes around the world gathered the data used to make the image. But even with many telescopes working together, holes remained in the data. In the latest study, scientists depended on the same data, but used machine learning methods to fill in the missing information. The resulting picture looks similar to the image, but with a thinner “doughnut” and a darker center, the researchers said. “For me, it feels like we're really seeing it for the first time,” said the lead writer of the study, Lia Medeiros. She is an astrophysicist at the Institute for Advanced Study in New Jersey. She said it was the first time the team had used machine learning to fill in the data holes.世界各地的射电望远镜网络收集了用于制作图像的数据。但即使有许多望远镜一起工作，数据中仍然存在漏洞。在最新的研究中，科学家们依赖于相同的数据，但使用机器学习方法来填补缺失的信息。研究人员说，由此产生的图片看起来与图像相似，但“甜甜圈”更薄，中心更暗。 “对我来说，感觉就像我们第一次真正看到它，”该研究的主要作者 Lia Medeiros 说。她是新泽西高等研究院的天体物理学家。她说，这是该团队第一次使用机器学习来填补数据漏洞。With a clearer picture, researchers hope to learn more about the black hole's properties and gravity in future studies. Medeiros said the team also plans to use machine learning on other images of space objects. This could include the black hole at the center of our galaxy, the Milky Way. The study's four writers are members of the Event Horizon Telescope (EHT) project. It is an international effort begun in 2012 with the goal of directly observing a black hole's nearby environment. A black hole's event horizon is the point beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation – can escape. Dimitrios Psaltis is an astrophysicist at Georgia Institute of Technology in Atlanta, Georgia. He told Reuters news agency the main reason the first image had many gaps is because of where the observing telescopes sit. The telescopes operate from the tops of mountains and “are few and far apart from each other,” Psaltis said.有了更清晰的图像，研究人员希望在未来的研究中更多地了解黑洞的特性和引力。 Medeiros 说，该团队还计划在其他空间物体图像上使用机器学习。这可能包括我们银河系中心的黑洞，即银河系。该研究的四位作者是事件视界望远镜 (EHT) 项目的成员。这是 2012 年开始的一项国际努力，目标是直接观察黑洞附近的环境。黑洞的事件视界是任何东西——恒星、行星、气体、尘埃和所有形式的电磁辐射——都可以逃逸的点。 Dimitrios Psaltis 是佐治亚州亚特兰大市佐治亚理工学院的天体物理学家。他告诉路透社，第一张图片有很多空隙的主要原因是观测望远镜所在的位置。 Psaltis 说，这些望远镜在山顶上运行，“数量很少，而且彼此之间距离很远”。As a result, the telescope system has a lot of 'holes' and scientists can now use machine learning methods to fill in those gaps, he added. "The image we report in the new paper is the most accurate representation of the black hole image that we can obtain with our globe-wide telescope," Psaltis said.因此，望远镜系统有很多“漏洞”，科学家现在可以使用机器学习方法来填补这些空白，他补充说。 Psaltis 说：“我们在新论文中报道的图像是我们用全球望远镜可以获得的最准确的黑洞图像。”

On 12 May 2022, the Event Horizon Telescope team announced the groundbreaking image of the Sgr A* black hole image which dwells in the center of our Milky Way galaxy.

Last week was an epic week for astronomers, mathematicians and astrophysicists around the world with the capturing of the first picture of a black hole in this galaxy.The picture shows a halo of dust and gas, tracing the outline of a colossal black hole, at the heart of the Milky Way, 27,000 light years from Earth. Known as Sagittarius A* the object is a staggering four million times the mass of our Sun.It was a particular thrill for the University of Canterbury's Canterbury Distinguished Professor Roy Kerr as it proved a his theory - posited more than 50 years ago -when he found the exact solution of Albert Einstein's equations that describe rotating black holes. Dr Kerr's colleague and University of Canterbury Professor of Physics David Wiltshire says it's an incredibly exciting development that will enhance understanding of the crucial role that supermassive black holes play in the life cycle and ecology of galaxies.

As COVID Cases Rises, Effectiveness Of Vaccines Lessens In Kids As parts of the country continue to see waves of infection from the omicron variant of COVID-19, parents of children over age five have taken heart at the availability of vaccines—while parents of kids five and under have continued to wait for an approved dose. But even as the case numbers continue to climb, the vaccines are less effective against the more-virulent omicron variants—and, for some reason, dramatically less effective in kids. Koerth joins Ira to discuss the story, and why experts say it's still worthwhile getting vaccinated even if the vaccines don't have the dramatic performance seen at the beginning of the vaccination phase of the pandemic. They also talk about a bird flu outbreak troubling poultry farms around the world, the odd immune system of the sleepy lizard, and how scientists are trying to catch a whiff of the odors of ancient Egypt.   Meet The ‘Gentle Giant,' Your Friendly Neighborhood Black Hole It wasn't long ago that the idea of capturing an image of a black hole sounded like a joke, or an oxymoron. How do you take a picture of something so dense that it absorbs the very light around it? But three years ago, we got our first good look with help from the Event Horizon Telescope, which is actually multiple radio telescopes all linked together. That picture was a slightly blurry, red-and-orange doughnut—the best picture to date of the supermassive black hole at the center of a galaxy called Messier 87, which is called Messier 87* or M87*. (Black holes are given an asterisk after the name of their location). Today, it's possible to buy jewelry and t-shirts with that picture, drink out of a M87*-adorned coffee cup, or just make it your phone background. Now that the first picture of a black hole is practically a pop culture meme, how do you one-up that? In the past weeks, the Event Horizon Telescope team alluded to a new ‘breakthrough' hiding in the Milky Way. On Thursday, the team unveiled that breakthrough: the first image of our nearest black hole neighbor in the heart of our galaxy. Sagittarius A* is a “gentle giant,” says Feryal Ozel, a member of the global collaboration that created this image. It consumes far less of the gas swirling nearby than M87*, and is far fainter as a result. The Milky Way's black hole also lacks the galaxy-spanning jets of M87* and, due to its smaller size, the gas around it moves so fast that it took years longer to capture a clear picture. Ira talks with Ozel about what it takes to obtain such a picture, and what it can tell us about the extreme, high-temperature physics of black holes throughout the universe.   What Was It Like To Witness The End Of The Dinosaurs? 66 million years ago, a massive asteroid hit what we know today as the Yucatán Peninsula of Mexico. Many people have a general idea of what happened next: The age of the dinosaurs was brought to a close, making room for mammals like us to thrive. But fewer people know what happened in the days, weeks, and years after impact. Increased research on fossils and geological remains from this time period have helped scientists paint a picture of this era. For large, non-avian dinosaurs like Triceratops and Tyrannosaurus rex, extinction was swift following the asteroid impact. But for creatures that were able to stay underwater and underground, their post-impact stories are more complicated. Joining Ira to discuss her book The Last Days of the Dinosaurs is Riley Black, science writer based in Salt Lake City, Utah.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

With the threat of coronavirus taking centre stage in all our minds, has the issue of plastic waste taken a backseat - has the public lost interest?In the pod this week are New Scientist journalists Valerie Jamieson, Graham Lawton and Adam Vaughan. They discuss a new study exploring ways to fix our ever-increasing problem of plastic pollution, which is being especially compounded by many of the world’s new hygiene measures and the dumping of thousands of tonnes of PPE. As different parts of the world look to tackle the issue differently, like the UK’s introduction of a plastic tax for instance, can we push back the worst of our plastic problems?The team also reexamines 2019’s groundbreaking image of a black hole, as a new study reveals what the fuzzy orange glow around the hole could tell us. They also find out how dinosaurs became one of the most successful groups of animals ever to exist, work out whether fungi found at Chernobyl could protect humans from the radiation on Mars, and take a closer look than ever before at the planet nearest to our sun, Mercury!To find out more, subscribe at newscientist.com/podcasts.

Some hours ago astrophysicists brought us the real look of a far away black hole for the first time in history. Numerous science fiction writers, artists, and thinkers have dreamt and visualised the image of a black hole before. But, this is the first time we see a real image of a black hole using powerful (wo)man-made telescopes. The target was a supermassive black hole located at the centre of the Messier 87 (M87) galaxy about 500 million trillion km away from Earth. It measures 40 billion km across, roughly 3.3 million times the size of the Earth. Let that sink in.
