Prof. Julien de Wit speaks with National Geographic reporter Robin George Andrews about how special infrared filters on the James Webb Space Telescope (JWST) can be used to find small asteroids and precisely determine their size. “Asteroids get much brighter in the infrared than in the visible as they move away from Earth, and they are thus easier to detect or track with infrared facilities—JWST being the biggest of all,” says de Wit.
Prof. Taylor Perron speaks with USA Today reporter Kate S. Petersen about the evidence that humans are changing the Earth’s climate. "What's alarmingly different about the global warming happening now is how fast it's happening and how it's clearly associated with humans adding greenhouse gases like carbon dioxide to the atmosphere," says Perron. "Rapid warming in the geologic past, long before there were humans, led to mass extinctions. And times when it was only slightly warmer than now, like before the last ice age, had sea levels high enough to flood most of today's coastal cities."
MIT Profs. Angela Belcher, Emery Brown, Paula Hammond and Feng Zhang have been honored with National Medals of Science and Technology, reports Michael T. Neitzel for Forbes. Additionally, R. Lawrence Edwards '76 received a National Medal of Science and Noubar Afeyan PhD '87, a member of the MIT Corporation, accepted a National Medal on behalf of Moderna. The recipients have been awarded “the nation’s highest honors for exemplary achievements and leadership in science and technology,” explains Neitzel.
Researchers at MIT and elsewhere have found “the smallest asteroids ever detected within the main belt, which is a field between Mars and Jupiter where millions of asteroids orbit,” reports Sabrina Lam for The Boston Globe. “With new technology, we can find populations of asteroids that were inaccessible previously,” says Prof. Julien De Wit. “Now we have the capability to be able to study this object further out, predict the orbit with much better accuracy, and decide what to do for potential or possible future impactors.”
Using the James Webb Space Telescope (JWST), MIT astronomers have spotted “small space rocks – including some just dozens of feet in length, the tiniest ever discovered in our solar system’s main asteroid belt between Mars and Jupiter,” reports Robin George Andrews for National Geographic. “This work helps to fill in astronomers’ understanding of the asteroid belt, the wreckage left behind from the inner solar system’s formation—and it’s always nice to spy more of those rocky time capsules for future study,” explains Andrews.
MIT scientists have discovered the smallest asteroids known to exist in the Main Asteroid Belt between Mars and Jupiter, reports Alfredo Carpineti for IFL Science. “The team of researchers behind this new discovery cleverly reused images from the search for exoplanets,” writes Carpineti. “Stacks of images looking at the same distant star field were used with a technique called “shift and stack”, which aims to highlight possible movement in the foreground, like from an asteroid. They were able to find 138 asteroids in the decameter size range.”
Prof. Benjamin Weiss, director of the MIT Paleomagnetism Lab, speaks with Forbes reporter Bruce Dorminey about the use of paleomagnetism to track the geographic origins of stromatolites. Weiss notes that he and his colleagues published a paper examining the magnetization of stromatolites in the Strelley Pool Chert in Australia’s Pilbara region. The team’s measurements show that these stromatolites formed within 8 degrees latitude of the equator, Weiss explains.
MIT researchers have analyzed tiny particles from a distant asteroid and found that a weak magnetic field may have helped form the outer planets in our solar system, reports Sabrina Lam for The Boston Globe. In the future, the researchers hope to use samples from other celestial bodies to identify magnetic fields in our universe. “An exciting thing that’s probably going to happen in the next few decades,” says Prof. Benjamin Weiss, “is that we’re going to start bringing samples back from comets.”
Graduate student Samantha Hasler and her colleagues have gathered new information on Uranus using the Hubble Space Telescope and the New Horizons spacecraft, reports Jamie Carter for Forbes. "Studying how known benchmarks like Uranus appear in distant imaging can help us have more robust expectations when preparing” for future missions, explains Hasler.
Prof. Kerry Emanuel speaks with Associated Press reporter Terry Spencer about Tampa Bay’s vulnerability to incoming hurricanes. “It’s a huge population,” explains Emanuel. “It’s very exposed, very inexperienced and that’s a losing proposition. I always thought Tampa would be the city to worry about most.”
Prof. Kerry Emanuel speaks with Washington Post reporters Sarah Kaplan, Shannon Osaka and Dan Stillman about the future of hurricane forecasting. “This is one thing that scares me, if these things can intensify more rapidly,” says Emanuel. “We’re going to have cases where forecasters go to bed with a tropical storm and wake up with a Category 5 when it’s too late to evacuate people.”
A new study by MIT researchers suggests that “Mars’ missing atmosphere may be locked up in the planet’s clay-rich surface,” reports Tom Howarth for Newsweek. “According to the researchers, ancient water trickling through Mars' rocks could have triggered a series of chemical reactions, converting CO2 into methane and trapping the carbon in clay minerals for billions of years,” explains Howarth.
Scientists from MIT and elsewhere are using submersible structures to harness the power of ocean waves and make sand accumulate in specific regions to protect islands and potentially grow new ones, reports Amy Gunia for CNN. “With each field experiment, the group says it is advancing its understanding of what materials, configurations, and construction techniques can make sand accumulate in the simplest, most cost-effective, sustainable, long-lasting and scalable way,” explains Gunia.
Researchers at MIT and elsewhere have discovered an exoplanet that “is 50% larger than Jupiter and as fluffy as cotton candy,” reports Aylin Woodward for The Wall Street Journal. “Basically, for over 15 years now, the astronomy community has been puzzled by a category of gas giants that are bigger than what they should be given their mass,” explains Prof. Julien de Wit.
MIT scientists have solved a decades old mystery by demonstrating impact vaporization is the primary cause of the moon’s thin atmosphere, reports Eric Lagatta for USA Today. The findings, “have implications far beyond determining the moon's atmospheric origins,” writes Lagatta. “In fact, it's not unthinkable that similar processes could potentially be taking place at other celestial bodies in the solar system.”
