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.
Blue Origin unveiled plans to send a spaceship to the moon, reports Seth Borenstein for the AP. Prof. Dava Newman explained that the newly designed rocket engine is what makes Blue Origin’s attempt to reach the moon unique. “It’s for real,” said Newman.
A new study by MIT researchers provides evidence that life on Earth may have begun in shallow bodies of water, reports Martin Finucane for The Boston Globe. The researchers found that ponds “could have held high concentrations of a key ingredient, nitrogen, while that would have been less likely in the ocean,” Finucane explains.
Boston Globe reporter Martin Finucane writes about how TESS has discovered an Earth-sized planet orbiting a star 52 light years from Earth. “The new planet HD, 21749c, orbits the star HD 21749. It circles the star in 7.8 days,” Finucane explains. “The planet is probably rocky and uninhabitable, with temperatures on the surface of up to 800 degrees.”
Forbes contributor Jamie Carter writes that TESS has identified an Earth-sized exoplanet orbiting a star 52 light years from Earth. The planet "takes about eight days to orbit the host star and is similar in size to Earth at 89% its diameter,” writes Carter. “A likely rocky world, it's thought to have surface temperatures as high as 800°F /427°C.”
The MIT-led TESS mission has discovered its first Earth-sized exoplanet, reports Ashley Strickland for CNN. “There was quite some detective work involved, and the right people were there at the right time,” says postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear."
