Researchers at MIT, including postdoctoral associate Marc Hon and research scientist Avi Shporer, have discovered a new disintegrating planet approximately 140 light-years away from Earth, reports Sarah Mesdjian for The Boston Globe. “The planet got so close to its star that the heat started evaporating its surface,” says Shporer. “The planet is not big enough to hold onto that material with its gravity.”
MIT astronomers have discovered a planet disintegrating at a rapid pace, reports Xinhua. “Roughly the size of Mercury, the planet orbits its host star at an extremely close distance - about 20 times closer than Mercury is to the Sun - completing a full orbit every 30.5 hours,” explains Xinhua. “Due to this intense proximity, researchers believe the planet is likely covered in molten magma, which is vaporizing and streaming into space.”
MIT researchers have uncovered BD+05 4868 Ab, “a planet that is disintegrating into boiling chunks of rock and evaporating minerals,” reports Andrew Paul for Popular Science. “Astronomers have only identified three disintegrating planets before BD+05 4868 Ab, all of which were detected over a decade ago using data collected by NASA’s Kepler Space Telescope,” explains Paul. “The newest find is the most violent example yet, with the longest tail and deepest transits of the four known examples.”
Astronomers at MIT have discovered a rapidly disintegrating planet “with a comet-like tail,” reports Ian Randall for Newsweek. “The planet is orbiting so close to its star that researchers estimate it has a surface temperature around 3,000 degrees Fahrenheit, giving it a molten surface that is boiling off material into space, where this cools to form a long, dusty tail,” explains Randall.
Gizmodo reporter Issac Schultz writes that researchers, including MIT astronomers, have found that a sudden brightening from a star about 12,000 light-years away was caused by a Jupiter-sized planet “doomed by a slow orbital death spiral.” Using NASA’s James Webb Space Telescope, the astronomers found that the “unfortunate, roughly-Jupiter-sized planet was orbiting way too close for comfort—closer to its host star than Mercury is to our Sun. Over millions of years, that orbit shrank until the planet skimmed the star’s atmosphere.”
Astronomers from MIT and other institutions have discovered a “supermassive black hole that appears to be ‘waking up’ after being inactive for decades,” reports Soo Kim for Newsweek. “The black hole at the heart of SDSS1335+0728—a distant galaxy 300 million light-years away—was found to have produced flashes of light known as quasi-periodic eruptions (QPEs),” Kim explains, adding that the “the bursts of X-rays from Ansky were found to be 10 times longer and 10 times more luminous than what we see from a typical QPE.”
Popular Science reporter Andrew Paul writes that a team of astronomers, including MIT scientists, has been studying a black hole dubbed Ansky that is in the process of waking up. Paul notes that what the researchers have documented "challenges prevailing theories about black hole lifecycles.” Graduate student Joheen Chakraborty explains: “The bursts of X-rays from Ansky are ten times longer and ten times more luminous than what we see from a typical QPE. Each of these eruptions is releasing a hundred times more energy than we have seen elsewhere. Ansky’s eruptions also show the longest cadence ever observed, of about 4.5 days.”
Prof. Sarah Millholland, Prof. Christian Wolf, Prof. Emil Verner, Prof. Darcy McRose, Prof. Marzyeh Ghassemi, Prof. Mohsen Ghaffari and Prof. Ariel Furst have received the 2025 Sloan Research Fellowship for “being among the most promising scientific researchers currently working in their fields,” reports Michael T. Nietzel for Forbes. “Sloan Research Fellows are chosen in seven scientific and technical fields—chemistry, computer science, Earth system science, economics, mathematics, neuroscience, and physics,” explains Nietzel.
MIT astronomers have analyzed the scintillation – or glistening - produced by a fast radio burst (FRB) to help identify the location of the pulses, reports Ashley Strickland for CNN. “We discovered that this FRB exhibits ‘twinkling,’ similar to how stars appear to twinkle in the night sky,” explains postdoc Kenzie Nimmo. “Observing this scintillation indicates that the region where the FRB originated must be incredibly small.”
USA Today reporter Eric Lagatta writes that a new study by MIT researchers finds that X-ray flashes emanating from a supermassive black hole located 270 million light-years from the Milky Way could be caused by a dead stellar remnant, or white dwarf. The researchers believe that the white dwarf could be “spinning precariously on the edge of the black hole, causing the explosions of high-energy light.”
MIT astronomers have detected X-ray flashes erupting from a supermassive black hole that seem to be caused by a nearby white dwarf, reports Will Dunham for Reuters. “It is probably the closest object we've ever observed orbiting around a supermassive black hole,” says graduate student Megan Masterson. “This is extremely close to the black hole's event horizon.”
MIT astronomers have witnessed flashes of X-rays shooting out of a black hole and believe that a dead star, or white dwarf, passing close by the black hole could be causing the eruptions, reports Mark Kaufman for Mashable. “The astronomers ran simulations of what could drive these unusual bursts of energy,” writes Kaufman. “The most plausible outcome is this brazen white dwarf (the spent core of a sun-like star), which is about one-tenth the mass of our sun. It's shedding its dense, outer layer and triggering these pulses of X-rays.”
Space.com reporter Robert Lea writes that using the XMM-Newton X-ray telescope, MIT astronomers have observed bursts of X-rays erupting with increasing frequency from a supermassive black hole, a behavior they think could be caused by a “dead stellar core, or white dwarf, daringly teetering on the edge of the black hole.” Lea explains that “if the source of these strange episodes is a finely balanced white dwarf, the researchers theorize that it could be detected using ripples in space and time called gravitational waves emitted from the system.”
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.”
