Astronomy and astrophysics

Guy Consolmagno '74, SM '75, director of the Vatican Observatory, speaks with Rebecca Mead of The New Yorker about his journey from suburban Detroit to MIT to his current role as the Pope’s Astronomer, and the intersection between science and religion. “If people think you have to be a weird kind of scientist to be religious, or a weird kind of religious to be a scientist, then we’ve missed the point,” says Consolmagno. “The point is that our faith—our ordinary faith—fits perfectly with our ordinary, but wonderful, delightful science.” 

Graduate student Isabella Macias speaks with CBS News about her experience studying astronomy and planetary formation at the Vatican Observatory. “The Vatican has such a deep, rich history of working with astronomers,” says Macias. “It shows that science is not only for global superpowers around the world, but it's for students, it's for humanity.” Br. Guy Consolmagno '74, SM '75, director of the Vatican Observatory, shares how he feels astronomy can help unite people around the world. 

Prof. Julien de Wit speaks with CNN reporter Ashley Strickland about asteroid 2024 YR4 and the importance of monitoring and studying asteroids to help keep Earth safe. 

Ten years after scientists detected gravitational waves for the first time using the LIGO detectors, Rachel Feltman of Scientific American's “Science Quickly” podcast visits the MIT LIGO Lab to speak with Prof. Matt Evans about the future of gravitational wave research and why Cosmic Explorer, the next generation gravitational wave observatory, will help unearth secrets of the early universe. “We get to look back towards the beginning of the universe, in some sense, with gravitational waves as we look at these sources that are farther and farther away,” says Evans. “With Cosmic Explorer we’ll have not just one or two but hundreds of thousands of sources from the distant universe. So it’s a really exciting way to explore the universe as a whole by looking at this stellar graveyard.”

Mashable reporter Elisha Sauers spotlights some of the exoplanets identified thus far in 2025, including BD+05 4868 Ab, a rocky exoplanet discovered by MIT astronomers that has a “comet-like tail stretching more than 5.5 million miles.” BD+05 4868 Ab is “about the size of Mercury and orbits its star every 30.5 hours,” Sauers explains. “At roughly 3,000 degrees Fahrenheit, the planet appears to be shedding material — about one Mount Everest’s worth per orbit — that becomes its tail.”

Using the Hubble Space Telescope, Prof. Julien de Wit and his colleagues have “detected microflares coming from the TRAPPIST-1 star every hour or so that last for several minutes,” reports Alex Wilkins for New Scientist. “These tiny bursts of radiation appear to interfere with our ability to observe the light that passes through the planets’ atmospheres – if they exist – thwarting the main method of detecting what chemicals might be in any atmospheres,” explains Wilkins. 

Gizmodo reporter Isaac Schultz writes that MIT astronomers have uncovered the most distant galaxy ever detected, dubbed MoM-z14, using the James Webb Space Telescope. Schultz notes that MoM-z14 “isn’t just some dim smudge, either—it’s unexpectedly luminous, echoing a growing theme in JWST’s discoveries. MoM-z14 now joins a strange new class of young galaxies that shine far more brightly than anyone expected.” 

MIT astronomers have found evidence that a massive asteroid impact billions of years ago “may have briefly amplified the moon's old, weak magnetic field, leaving behind a magnetic imprint still detectable in lunar rocks,” reports Sharmila Kuthunur for Space.com. “While the moon once had a weak magnetic field generated by a small molten core, the team's research suggests it likely wouldn't have been strong enough on its own to magnetize surface rocks,” Kuthunur explains. “However, a massive asteroid impact may have changed that — at least briefly.”

Ars Technica reporter Jennifer Oulette writes that MIT researchers have found that a “large asteroid impact briefly boosted the Moon's early weak magnetic field—and that this spike is what is recorded in some lunar samples.” 

Postdoc Rohan Naidu and his colleagues have used the James Webb Space Telescope (JWST) to examine galaxy MoM-z14, first spotted in 2023, reports Jonathan O’Callaghan for New Scientist. “Naidu and his colleagues confirmed MoM-z14 is the most distant galaxy yet,” writes Naidu. “The light we see now was emitted just 280 million years after the big bang, breaking the previous record by about 10 million years.” 

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.”
