Researchers at MIT and elsewhere have discovered a “black-hole triple, the first known instance of a three-body system that includes a black hole, which is not supposed to be part of the mix,” reports Dennis Overbye for The New York Times. The researchers propose that the black hole “could have resulted from a sort of immaculate conception whereby the progenitor star disappeared from the universe without any fireworks.”
Astronomers from MIT and elsewhere have “identified a black hole that appears to have come into being through the collapse of the core of a large star in its death throes, but without the usual blast,” explains Will Dunham for Reuters. “Black holes have previously been spotted orbiting with one other star or one other black hole in what are called binary systems,” explains Dunham. “But this is the first known instance of a triple system with a black hole and two stars.”
Researchers from MIT and elsewhere have discovered a black hole triple – a black hole with two orbiting stars around it at varying distances – for the first time, reports Jess Thomson for Newsweek. The researchers believe this “first-of-its-kind discovery could help unravel the mysteries of how black holes form and how they enter into binaries or triples,” writes Thomson.
Popular Science reporter Laura Baisas writes that MIT physicists have discovered, for the first time, a black hole triple. “Since the new triple system includes a very far-off star, the system’s black hole was potentially born through [a] gentler direct collapse,” writes Baisas. “While astronomers have been observing violent supernovae for centuries, this new triple system may be the first evidence of a black hole that formed from this more gentle process.”
Physicists from MIT and Caltech have discovered a black hole triple system, “consisting of three bodies spinning around each other about 7,800 light-years from Earth,” writes Isaac Schultz for Gizmodo. Schultz notes that the finding “pushes the envelope,” revealing “a system with one black hole and two stars—a configuration never seen before.”
Boston Globe reporter Nick Stoico spotlights how researchers from MIT and Caltech have observed a “black hole triple” for the first time. “This one is satisfying because it’s kind of a simple discovery,” explains postdoctoral associate Kevin Burdge. “It’s just looking at a picture, and I think it reminds a lot of astronomers that there’s more to the job than just analyzing complicated data. You shouldn’t forget to do the simple things, like just look with your own eyes at some pictures and see what you find.”
Using the James Webb Telescope, researchers at MIT have found quasars, “some of the brightest objects in the cosmos, adrift in the empty voids of space,” reports Mark Kaufman for Mashable. “This latest cosmic quandary is not just about how these quasars formed in isolation, but how they formed so rapidly,” explains Kaufman.
Researchers at MIT and elsewhere have found a connection between “the bursts and tidal disruptions events” of black holes, research that could help "astrophysicists understand the extreme environments around supermassive black holes, as well as the occupants of those environments,” reports Isaac Schultz for Gizmodo. “There had been feverish speculation that these phenomena were connected, and now we’ve discovered the proof that they are,” says Research Scientist Dheeraj Pasham. “It’s like getting a cosmic two-for-one in terms of solving mysteries.”
CNN’s Ashley Strickland reports on the discovery of an exoplanet on the path to becoming a “hot Jupiter,” providing clues about the evolution of these massive Jupiter-like planets closely orbiting their host stars. As Prof. Sarah Millholland explains: “This system highlights how incredibly diverse exoplanets can be. They are mysterious other worlds that can have wild orbits that tell a story of how they got that way and where they’re going.”
Prof. Sara Seager, Prof. Robert Langer and Prof. Nancy Kanwisher have been awarded the 2024 Kavli Prize for their work in the three award categories: astrophysics, nanoscience, and neuroscience, respectively, reports Michael T. Nietzel for Forbes. According to the Norwegian Academy of Science and Letters, this award honors scientists with outstanding research “that has broadened our understanding of the big, the small and the complex,” writes Nietzel.
NBC Boston reporter Matt Fortin visits the lab of Prof. Julien de Wit to learn more about his work discovering two new planets, a puffy, Jupiter-sized planet located over 1,000 light years away that has the consistency of cotton candy and an Earth-sized planet that may lack an atmosphere. “Through studying other atmospheres we get to improve our understanding of our own climate,” de Wit explains. “It’s like a sensitive mirror that helps us reflect back on us, so it’s all these different vantage points that we are gaining. That’s what exoplanetary science gives us.”
Prof. Anna Frebel joins Arun Rath of WGBH’s All Things Considered to discuss her recent discovery of some of the universe’s oldest stars, an out-of-this-world identification made the help of MIT undergraduates Hillary Andales, Ananda Santos and Casey Fienberg. “When you meet someone new, you want to know what their name is, how old they are, maybe where they live and what they do, right?” says Frebel. “We do the same with all the astronomical objects in the sky.”
MIT astronomers measured a black hole’s spin for the first time by tracking the X-ray flashes produced by a black hole following a tidal disruption event, reports Interesting Engineering’s Mrigakshi Dixit. “The spin value of a black hole tells us about how it evolved over the age of the universe,” explains Research Scientist Dheeraj Pasham.
MIT astronomers have found a new way to measure how fast a black hole spins, observing the aftermath of a black hole tidal disruption event with a telescope aboard the International Space Station, reports Laura Baisas for Popular Science. “The only way you can do this is, as soon as a tidal disruption event goes off, you need to get a telescope to look at this object continuously, for a very long time, so you can probe all kinds of timescales, from minutes to months,” said Research Scientist Dheeraj Pasham.
Astronomers at MIT and elsewhere have determined how to measure the spin of a nearby supermassive black hole using a new calculation method, reports Isaac Schultz for Gizmodo. The team “managed to deduce a supermassive black hole’s spin by measuring the wobble of its accretion disk after a star has been disrupted—a polite word for torn up—by the gigantic object,” explains Schultz. “They found the black hole’s spin was less than 25% the speed of light—slow, at least for a black hole.”
