Research scientists Clara Sousa-Silva and Janusz Petkowski speak with NPR’s Nell Greenfieldboyce about their new study that provides evidence that phosphine, a gas associated with microbial life, is present on Venus. "This is not life that we would find pleasant," says Sousa-Silva. "Then again, they probably find us disgusting."
An international team of astronomers has detected phosphine on Venus, potentially signaling signs of life in the planet’s atmosphere, reports Shannon Stirone, Kenneth Chang and Dennis Overbye for The New York Times. "This is an astonishing and ‘out of the blue’ finding,” says Prof. Sara Seager. “It will definitely fuel more research into the possibilities for life in Venus’s atmosphere.”
Los Angeles Times reporter Deborah Netburn spotlights how a team of researchers, including MIT scientists, have detected phosphine on Venus. “There are two possibilities for how it got there, and they are equally crazy,” says Prof. Sara Seager. “One scenario is it is some planetary process that we don’t know about. The other is there is some life form living in the atmosphere of Venus.”
Verge reporter Loren Grush explores how researchers from MIT and other institutions have uncovered phosphine on Venus, a potential sign of life. “That’s why this is such an extraordinary detection, because it has to come from something completely unexpected,” says research scientist Clara Sousa-Silva. “At some point, you’re left with not being able to explain it. Except we do know of a strange way of making phosphine on terrestrial planets — and that is life.”
Scientists from institutions around the world, including MIT, have found detected phosphine gas in the clouds of Venus, reports Tom Metcalfe for NBC News. “If this signal is correct, there is a process on Venus we cannot explain that produces phosphine,” says research scientist Janusz Petkowski, “and one of the hypotheses is that it’s life in the clouds of Venus.”
Axios reporter Miriam Kramer writes about a new study co-authored by MIT researchers that details the detection of phosphine, a possible signal of life, in the atmosphere of Venus. “We've done everything we can, which is go through all the things that it isn't,” says research scientist Clara Sousa-Silva. “We've thought of every possible mechanism, plausible or implausible, that could make phosphine and we cannot come up with any."
A study by MIT researchers uncovers evidence that the Earth’s global ice ages were triggered by a rapid drop in sunlight, reports Mashable. The researchers found that an “event like volcanic eruptions or biologically induced cloud formation will be able to block out the sun and limit the solar radiation reaching the surface at a critical rate that can potentially trigger ‘Snowball Earth’ events.”
Forbes contributor Bruce Dominey writes that a study by MIT researchers finds global ice ages may have been triggered by a rapid decrease in the amount of solar radiation reaching Earth. “Past Snowball glaciations are more likely to have been triggered by changes in effective solar radiation than by changes in the carbon cycle,” writes Dominey.
CNN’s Ashley Strickland highlights how MOXIE, a device that the Mars 2020 rover will carry on board to convert carbon dioxide into oxygen, could aid future human exploration of Mars. "MOXIE is so you don't have to take an estimated 27 metric tons of oxygen to Mars just to get them off the surface," said Dr. Mike Hecht, principle investigator for MOXIE.
The Economist explores how the Transiting Exoplanet Survey Satellite (TESS), an MIT-led NASA mission, has identified a number of new exoplanets and, in the process, helped astronomers and scientists unearth new details about our universe. This latest discovery, according to The Economist, “will help answer some of the biggest questions in the rapidly growing science of exoplanetology.”
Cecelia Smith-Schoenwalder writes for US News & World Report about the planet hunting satellite TESS, which has recently discovered three new exoplanets. "The pace and productivity of TESS in its first year of operations has far exceeded our most optimistic hopes for the mission," said Senior Research Scientist George Ricker, TESS's principal investigator.
Martin Finucane reports for The Boston Globe on the latest findings of the Transiting Exoplanet Survey Satellite, “a NASA Astrophysics Explorer mission led and operated by MIT and managed by NASA’s Goddard Space Flight Center,” which hunts for exoplanets. TESS recently discovered a rocky super-Earth and two sub-Neptunes in a system known as TOI-270.
A new MIT study shows that NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered three new exoplanets in a system known as TOI-270. “The newly discovered exoplanets are some of the smallest and closest ever found,” reports Ashley Strickland for CNN. “All three planets are similar in size, which is very different from our own solar system filled with extremes.”
Postdoc Maximilian Günther is the lead author on a paper showing that NASA’s TESS satellite has discovered three new exoplanets. “The exoplanets are of a type that does not exist in our solar system, being between the Earth and Neptune in size,” writes Daniel Clery for Science. “That makes the closely packed system, known as TOI-270, a good bet for answering long-standing questions about how such ‘super-Earths’ or ‘mini-Neptunes’ form.”
TESS, an MIT-led NASA mission, has discovered two gaseous exoplanets and one rocky exoplanet within a system known as TOI-270, reports New Scientist. “TOI-270 will soon allow us to study this ‘missing link’ between rocky Earth-like planets and gas-dominant mini-Neptunes, because here all of these types formed in the same system,” says postdoc Maximilian Günther, lead author of a paper on the new system.
