Marcos Berríos ‘06, Christina Birch PhD ’15, and Christopher Williams PhD ’12 are among the ten selected to be a part of NASA’s 2021 astronaut candidate class, reports Emre Kelly for USA Today. “Flanked by T-38 Talon jets to be used over their two-year training course at Johnson Space Center in Houston, NASA officials introduces the 2021 class of six men and four women in front of their families, friends, and soon-to-be colleagues,” writes Kelly.
Marcos Berríos ‘06, Christina Birch PhD ‘15 and Christopher Williams PhD ’12 have been selected as part of NASA’s 2021 astronaut candidate class, reports WBUR’s Bill Chappell. “Alone, each candidate has ‘the right stuff,’ but together they represent the creed of our country: E pluribus unum – out of many, one,” said NASA Administrator Bill Nelson.
Marcos Berríos ‘06, Christina Birch PhD ‘15, Christopher Williams PhD ‘12 are among the ten astronauts selected for the 2021 NASA astronaut class, reports Breanna Kovatch for The Boston Globe. “The class of astronauts were selected from among 12,000 candidates and is the first class in four years,” writes Kovatch.
CNN reporter Ashley Strickland writes that NASA’s Transiting Exoplanet Survey Satellite (TESS), an MIT-led mission, has discovered an exoplanet approximately the size of Mars where a year lasts for about eight hours. “Astronomers are eager to learn more about these small planets that quickly spin around their stars in less than 24 hours because they are not sure how they form and end up in such an extreme orbit,” writes Strickland.
A team of astronomers, including MIT researchers, has discovered an ultrahot Jupiter that orbits its star in just 16 hours, reports Robert Lea for Newsweek. “Ultrahot Jupiters such as TOI-2109b constitute the most extreme subclass of exoplanet,” explains former MIT postdoc Ian Wong. “We have only just started to understand some of the unique physical and chemical processes that occur in their atmospheres – processes that have no analogs in our own solar system.”
Newsweek reporter Robert Lea writes that astronomers from MIT and elsewhere have found evidence of a large planetary collision that stripped the atmosphere from a planet. “While astronomers have long believed these kinds of collisions are common throughout the Universe, this is the first time that they have spotted evidence of one that stripped an atmosphere in such a way around a distant star,” writes Lea.
A new study co-authored by MIT researchers presents the first evidence that a distant planet had its atmosphere partially blown away by a large impact, reports Charles Choi for Space.com. "I think a really critical implication is that the gas that is released in the aftermath of a giant impact can last for a long time, and it can affect the way the system evolves long-term," explains graduate student and lead author Tajana Schneiderman.
Researchers from MIT and other institutions have been able to observationally confirm one of Stephen Hawking’s theorems about black holes, measuring gravitational waves before and after a black hole merger to provide evidence that a black hole’s event horizon can never shrink, reports Caroline Delbert for Popular Mechanics. “This cool analysis doesn't just show an example of Hawking's theorem that underpins one of the central laws affecting black holes,” writes Delbert, “it shows how analyzing gravitational wave patterns can bear out statistical findings.”
CNN reporter Ashley Strickland writes about how researchers from the CHIME collaboration have announced that they have detected over 500 fast radio bursts (FRBs) using a radio telescope in Canada. "With all these sources, we can really start getting a picture of what FRBs look like as a whole, what astrophysics might be driving these events, and how they can be used to study the universe going forward," explains graduate student Kaitlyn Shin.
Scientists from the CHIME Collaboration, including MIT researchers, have reported that the radio telescope has detected more than 500 fast radio bursts in its first year of operation, reports Davide Castelvecchi for Nature. The findings suggest that these events come in two distinct types. “I think this really just nails it that there is a difference,” says Prof. Kiyoshi Masui.
The CHIME radio telescope has catalogues more than 500 fast radio bursts (FRBs), which could be used to help map the universe, reports Charlie McKenna for The Boston Globe. FRBs are “kind of like lighthouses or sonar pings,” explains graduate student Calvin Leung, “and for the very first time we’ve shown that we can detect them in large enough quantities that you can really use them to make statements like, ‘Oh, the universe is expanding at this rate,’ or ‘This is how much matter there is in the whole universe.’”
Inverse reporter Passant Rabie explores how the CHIME radio telescope has identified more than 500 fast radio bursts in its first year of operation, providing clues as to the structure of the universe. “With enough of them, they are going to be the ultimate tool for mapping the universe,” says Prof. Kiyoshi Masui.
Axios reporter Miriam Kramer writes that a new study co-authored by MIT researchers suggests that all black holes go through a similar cycle when feeding, whether they are big or small. “Black holes are some of the most extreme objects found in our universe,” writes Kramer. “By studying the way they grow, scientists should be able to piece together more about how they work.”
Boston Globe reporter Charlie McKenna writes that a new study co-authored by MIT researchers finds that the way black holes evolve as they consume material is the same, no matter their size. “What we’re demonstrating is, if you look at the properties of a supermassive black hole in the cycle, those properties are very much like a stellar-mass black hole,” says research scientist Dheeraj “DJ” Pasham. The findings mean “black holes are simple, and elegant in a sense.”
Academic Times reporter Monisha Ravisetti writes that a new study by physicists from a number of institutions, including MIT, finds that supermassive black holes devour gas just like their smaller counterparts. “This is demonstrating that, essentially, all black holes behave the same way,” says research scientist Dheeraj “DJ” Pasham. “It doesn’t matter if it’s a 10 solar mass black hole or a 50 million solar mass black hole – they appear to be acting the same way when you throw a ball of gas at it.”
