Prof. Jack Wisdom and his colleagues have found that “Saturn’s rings are a result of a moon that was torn apart by the planet’s tidal forces about 160 million years ago,” reports Jamie Carter for Forbes. “Wisdom and his co-researchers have dubbed the moon Chrysalis after the process of Chrysalis transforming into a butterfly,” writes Carter.
Reuters reporter Will Dunham writes that scientists from MIT and other institutions have found that the destruction of a large moon, called Chrysalis, that “strayed too close to Saturn would account both for the birth of the gas giant planet's magnificent rings and its unusual orbital tilt of about 27 degrees.” Prof. Jack Wisdom explained that "as a butterfly emerges from a chrysalis, the rings of Saturn emerged from the primordial satellite Chrysalis.”
A new study co-authored by MIT scientists proposes that Saturn’s rings could have been created when a lost moon of Saturn’s became unstable and crashed into the planet, reports Katie Hunt for CNN. “While the gas giant likely swallowed 99% of the moon, the remainder became suspended in orbit, breaking into small icy chunks that ultimately formed the planet’s rings,” writes Hunt.
Prof. Jack Wisdom and his colleagues have found that Saturn may have acquired its tilt and rings from a lost moon that was destroyed, reports Leah Crane for New Scientist. “Simulations using data from the Cassini spacecraft shows that an additional moon between Titan and Iapetus, destroyed between 100 million and 200 million years ago, could explain both of these long-standing mysteries,” explains Crane.
Prof. Jack Wisdom is the lead author of a new study that proposes “Saturn and Neptune’s gravity may have once been in sync, but Saturn has since escaped Neptune’s pull due to a missing moon,” reports Laura Baisas for Popular Science.
The Venus Life Finder (VLF) developed by scientists at MIT will be launched on a Rocket lab Electronic in May of 2023 to search for life in the upper atmosphere of Venus, reports Mark R. Whittington for The Hill. “When it plunges into Venus’ atmosphere it will use an instrument called the ‘autofluorescing nephelometer’ that will use a laser to illuminate organic molecules that may or may not exist 50 kilometers above the planet’s surface,” writes Whittington.
Prof. Wanying Kang and her colleagues have found that “the way ice covers the surface of Saturn’s moon Enceladus suggests that the oceans trapped beneath it may be only a little less salty than Earth’s oceans,” reports By Karmela Padavic-Callaghan for New Scientist. “The researchers found that saltier subsurface oceans correspond to thicker ice on a planet’s poles than over its equator and vice versa for less salty water,” writes Padavic-Callaghan.
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.”
Prof. Robert Simcoe and his team will receive 100 hours with the new James Webb Space Telescope to look at some of the first stars and galaxies to form after the Big Bang, reports David Bienick for WCVB. “I’m tremendously excited,” says Simcoe. “We have been preparing for this moment since 2016, knowing that we were going to have time and starting to prepare our observations, and waiting for the telescope to be ready.”
Associate Provost Richard Lester and Prof. Noelle Selin speak with Tiziana Dearing, host of Radio Boston, about MIT’s Climate Grand Challenges. “To me, the Climate Grand Challenges effort really represents that we’re kind of at a frameshift when thinking about the climate problem. It’s not just a problem that some people can work on,” says Selin. “A climate challenge is a whole of society challenge, and therefore it really has to be a whole of MIT challenge.” Lester adds he hopes the challenges will “inspire a new generation of students to roll up their sleeves, put their shoulders to the wheel and help us solve this problem.”
Prof. Kerry Emanuel speaks with AP reporter Seth Borenstein about the upcoming hurricane season and his research showing an increase in Atlantic storms over the past 150 years.
MIT announced five projects "targeting the world's toughest climate riddles" that were selected following a rigorous two-year competition, reports Benjamin Kail for Boston Business Journal. “Climate Grand Challenges represents a whole-of-MIT drive to develop game-changing advances to confront the escalating climate crisis, in time to make a difference,” says President L. Rafael Reif.
A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.
A campaign led by RRS Discovery, and Prof. Raffaele Ferrari has found that deep-ocean water rises due to the turbulence created by undersea mountains, reports Paul Voosen for Science. “The turbulence that was found tended to grow with depth. Like a spoon stirring milk into coffee, it was driving water down, not up, says Ferrari,” writes Voosen.
