A team of astronomers, including researchers from MIT, witnessed a star swallowing up an entire planet for the first time, reports Margaret Osborne for Smithsonian Magazine. “For decades, scientists have only been able to witness the before and after of such planetary engulfment,” writes Osborne.
Researchers from MIT and elsewhere have observed, for the first time, a dying star consuming a planet, reports Jack Guy for CNN. “The fact that the solar system planets would get engulfed into the sun in the future was something I had read first in high school, so it was surreal to realize that we may have found the first ever example of catching a similar event in real time,” says postdoc Kishalay De.
Reuters reporter Will Dunham writes that scientists from MIT and elsewhere have “observed a star, bloated in its old age, swallowing a Jupiter-like planet, then expelling some material into space in an energetic belch.” Postdoc Kishalay De notes that "this planet doesn't go out without a fight. Even before it is engulfed whole, our data provides evidence that the planet tries to rip out the star's surface layers with its own gravity. But the star happens to be a thousand times more massive so the planet can't do much and eventually makes the plunge.”
Researchers from MIT, Harvard, Caltech and elsewhere have spotted a hot, Jupiter-sized world being ingested by a sun-like star, reports Kasha Patel for The Washington Post. “The hope is that we would actually be able to use this entire new suite of instruments to try to find every single planet being engulfed in our galaxy in real time,” explains postdoc Kishalay De. “That’s only going to become possible now because of this discovery and together with the availability of instrumentation.”
Postdoc Kishalay De speaks with NPR’s Nell Greenfieldboyce about how he and his colleagues have observed, for the first time, a sun-like star consuming an orbiting planet. "We weren't quite looking for this. We were looking for similar things, but not quite this," says De. "Like a lot of discoveries in science, this happened to be an accidental discovery that really opened our eyes to a new type of phenomenon."
New York Times reporter Becky Ferreira spotlights how astronomers from MIT, Harvard, Caltech and elsewhere have spotted a dying star swallowing a large planet, “offering the first direct glimpse of a gnarly process called planetary engulfment that most likely awaits Earth in the deep future.” Postdoc Kishalay De explains that: “Finding an event like this really puts all of the theories that have been out there to the most stringent tests possible. It really opens up this entire new field of research.”
A team of astronomers from MIT and other institutions have detected a “sun-like star gobbling up a planet and belching out a blast of light and energy,” reports Leah Crane for New Scientist. “In the past, all of the evidence that we’ve had of stars eating planets is from looking at stars that have done that hundreds of thousands of years ago,” says postdoc Kishalay De. “But we have never caught a star red-handed eating a planet.”
AP reporter Marcia Dunn writes that scientists from MIT, Harvard, Caltech and elsewhere have “caught a star in the act of swallowing a planet — not just a nibble or bite, but one big gulp.” Dunn explains that: “Massachusetts Institute of Technology researcher Kishalay De spotted the luminous outburst in 2020 while reviewing sky scans taken by the California Institute of Technology’s Palomar Observatory. It took additional observations and data-crunching to unravel the mystery: Instead of a star gobbling up its companion star, this one had devoured its planet.”
Astronomers from MIT, Harvard, Caltech and other institutions have, for the first time, captured the moment when a star swallows a nearby planet, reports Ian Sample for The Guardian. “Like a lot of discoveries in science, this happened to be an accidental discovery that really opened our eyes to a new type of phenomenon,” explains postdoctoral scholar Kishalay De. “This is going to be the final fate of Earth.”
Researchers at MIT co-authored a study which found that two stars in a binary system 3,000 light years from Earth are orbiting each other so closely that one of the stars has burnt out, reports Will Dunham for Reuters. "Basically, they were bound together for 8 billion years in a binary orbit,” says postdoc Kevin Burdge, “And now, right before the second one could end its stellar life cycle and become a white dwarf in the way that stars normally do - by evolving into a type of star called a red giant - the leftover white dwarf remnant of the first star interrupted the end of the companion's lifecycle and started slowly consuming it."
Researchers at MIT have developed an automated search tool that can help astronomers identify the echoes emitted by a specific type of black hole, reports Juandre for Popular Mechanics. “The team’s algorithm, which they dubbed the ‘Reverberation Machine,’ pored through data collected by the Neutron Star Interior Composition Explorer, an x-ray telescope mounted to the International Space Station,” writes Juandre. “They identified previously undetected echoes from black hole binary systems in our galaxy.”
MIT astronomers have used light echoes from X-ray bursts to try to map the environment around black holes, reports Dennis Overbye for The New York Times. Prof. Erin Kara then worked with education and music experts to transform the X-ray reflections into audible sound. “I just love that we can ‘hear’ the general relativity in these simulations,” said Kara.
CNN reporter Ashley Strickland writes that MIT astronomers developed an automated search tool and were able to “pin down the locations of eight rare pairings of black holes and the stars orbiting them, thanks to the X-ray echoes they release.”
Vice reporter Becky Ferreira writes that MIT researchers developed a new system, called the Reverberation Machine, to detect the echoes from eight new echoing black hole binaries. “These echoes offer a rarely seen glimpse into the otherworldly surroundings of stellar-mass black holes, which are about five to 15 times the mass of the Sun,” writes Ferreira.
MIT researchers have detected eight echoing black hole binaries in the Milky Way and then converted the black hole X-ray emissions into sound waves, reports Isaac Schultz for Gizmodo. The researchers developed a new tool, dubbed the Reverberation Machine, which “combed satellite data from NICER, a telescope aboard the International Space Station that studies X-ray emissions from sources like black holes and neutron stars, including a weird type of emission known as an ‘echo.’”
