Researchers at MIT and Stanford have developed a new tool that can better map the inside of an asteroid that risks crashing into earth, writes Pranshu Verma for The Washington Post. “Understanding the interior," said Prof. Julian De Witt, "helps us understand the extent to which close encounters could be of concern, and how to deal with them.”
A new tool developed by researchers at MIT and Stanford could help map out the interior of asteroids, reports Alison Synder and Miriam Kramer for Axios. This could make “it easier to know the most effective way of throwing them off-course,” writes Synder and Kramer.
Prof. Susan Solomon speaks with Associated Press reporter Seth Borenstein about the Antarctic ozone hole. “’Ozone depletion starts LATER and takes LONGER to get to the maximum hole and the holes are typically shallower’ in September, which is the key month to look at ozone recovery, not October,” says Solomon.
Prof. Richard Binzel speaks with CBS News reporter David Pogue about asteroids and the Torino scale, a 10-point danger scale for asteroids that he created. "All the objects [asteroids] we know of today reside at zero or one, which simply means they're so small that they don't matter, or that we know for sure there's no impact possibility," says Binzel.
Prof. Kerry Emanuel discusses the impact climate change has on hurricanes, reports Robinson Meyer for The Atlantic. “First of all, you can have more intense hurricanes in a warmer climate. That finding goes back well over 30 years now,” says Emanuel. “For that reason we expect to see more of the highest-category storms—the Cat 3s, Cat 4s, Cat 5s, more of the Ian-style storms.”
Prof. Kerry Emanuel speaks with Newsweek reporter Pandora Dewan about Hurricane Ian and its correlation to climate change, reports Pandora Dewan for Newsweek. “What worries people in my profession is the confluence of two trends," says Emanuel. "One is demographic, one is nature. The number of people exposed to hurricanes has tripled since 1970 [as] people are moving in droves to hurricane-prone regions. Then the climate is changing, and that is demonstrably increasing the incidence of high-end storms like Ian."
Prof. Tanja Bosak speaks with Science reporter Eric Hand about how scientists plan to study rock samples from Mars for clues as to whether the planet once had a magnetic field and for signs of ancient life, such as the tough lipid molecules that can form cell walls. “You hope for an outline of a cell,” she says. “You will never find peptides and proteins, but lipids can persist.”
Prof. Jack Wisdom and his colleagues have found that Saturn’s rings are comprised of debris from its former moon, reports Marina Koren for The Atlantic. “The researchers say the moon’s demise was mostly Titan’s fault. The big moon jostled the smaller one, putting the object on a very elongated track around Saturn,” writes Koren.
Scientists at MIT and the Woods Hole Oceanographic Institution (WHOI) have found that while albatross couples typically mate for life, shy wandering albatross males are more likely to be divorced, reports Forbes. “This link between personality and divorce could help scientists predict the resilience of an albatross population over time."
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.
