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.”
Research scientist Mary Knapp and her collaborators are working on a concept for The Great Observatory for Long Wavelengths (Go-LoW), a space-based observatory comprised of small satellites aimed at making low-frequency radio waves visible, reports Ashley Strickland for CNN. “I learned back in my undergrad days that there was this part of the spectrum we couldn’t see,” Knapp explains. “It really just struck me that there was this unexplored part of the universe, and I want to explore this part of the sky for the first time.”
Research Scientist Mary Knapp’s proposal for a Great Observatory for Long Wavelengths (GO-LoW), a space-based observatory consisting of thousands of satellites that could study the magnetic fields of distant and rocky exoplanets, has been selected for NASA’s Innovative Advanced Concepts programs, writes George Dvorsky for Gizmodo.
A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”
Researchers at MIT and elsewhere have discovered a new exoplanet within a star’s habitable zone, reports Popular Mechanics. The exoplanet “requires further investigation to see if [it] has a life-supporting atmosphere – and possibly water,” writes Popular Mechanics.
Prof. Julien de Wit speaks with Newsweek reporter Ed Browne about the wealth of information that the James Webb telescope will be providing about the universe. "In terms of information content, we're pretty much going from listening to the radio, to having television," said de Wit.
Reporting for The Boston Globe, Hanna Kreuger highlights a graph documenting the atmospheric conditions of the exoplanet WASP-96b, which NASA included in its first release of images from the James Webb Space Telescope. Describing it as “perhaps the image that showcases Webb’s greatest triumph,” Krueger notes that the graph was created using an equation developed by Prof. Sara Seager. Seager and her team will use the telescope to peer into TRAPPIST-1e, an exoplanet widely considered to be potentially Earth-like and habitable, adds Krueger.
As the first images from the James Webb Space Telescope were released on Tuesday, showcasing the deepest view of the universe ever, CBS Boston spoke with Prof. Julien de Wit about the importance of the moment. “It’s groundbreaking. It’s like going from listening to the radio to suddenly being able to watch television,” says de Wit. “Further down the road, we may be able to see if planets are habitable, if some of these planets have signs of life one way or the other. There are so many things we’re going to discover thanks to it.”
Astronomers have identified two Earth-sized exoplanets orbiting a red dwarf star 33 light years away, reports Jamie Carter for Forbes. “Both planets in this system are each considered among the best targets for atmospheric study because of the brightness of their star,” explains postdoc Michelle Kunimoto.
To celebrate the list of known exoplanets topping 5,000, New York Times reporter Becky Ferreira spoke with astronomers, actors and astronauts about their favorite exoplanets or exoplanetary systems. “TOI-1233 is an outstanding planetary system with its high number of transiting planets, sunlike host star and its proximity to the solar system,” says postdoc Tansu Daylan of the system he detected along with two high school students he was mentoring.
MIT astronomers have observed the dark side of a football-shaped exoplanet known as WASP-121b and found that it may have metal clouds made up of iron, corundum, and titanium, reports Isaac Schultz for Gizmodo. “The vastly different temperatures on either side of the planet make a dynamic environment for the various molecules floating around the atmosphere,” writes Schultz. “In the daytime, water gets ripped apart by the nearly 5,000° Fahrenheit heat and blown to the night side of the planet by 11,000-mile-per-hour winds.”
CNN reporter Ashley Strickland writes that MIT researchers have observed the dark side of an exoplanet that is 855 light years from Earth and found that the gas giant may have metal clouds and rain containing liquid gems. The researchers found that the “exoplanet has a glowing water vapor atmosphere and is being deformed into the shape of a football due to the intense gravitational pull of the star it orbits,” writes Strickland.
TESS, a NASA mission led and operated by MIT, has discovered over 5,000 planets candidates outside of our solar system, reports Ed Browne for Newsweek. “This time last year, TESS had found just over 2,400 TOIs (TESS Objects of Interest),” says postdoctoral associate Michelle Kunimoto. “Today, TESS has reached more than twice that number – a huge testament to the mission and all the teams scouring the data for new planets.”
