Prof. Sara Seager speaks with New York Times reporter Dennis Overybye about the James Webb Telescope. Seager is part of a team that is planning to use the telescope to observe an exoplanet named Trappist-1e to determine if the planet has an atmosphere.
CNN reporter Ashley Strickland writes that NASA’s Transiting Exoplanet Survey Satellite (TESS), an MIT-led mission, has discovered an exoplanet approximately the size of Mars where a year lasts for about eight hours. “Astronomers are eager to learn more about these small planets that quickly spin around their stars in less than 24 hours because they are not sure how they form and end up in such an extreme orbit,” writes Strickland.
A team of astronomers, including MIT researchers, has discovered an ultrahot Jupiter that orbits its star in just 16 hours, reports Robert Lea for Newsweek. “Ultrahot Jupiters such as TOI-2109b constitute the most extreme subclass of exoplanet,” explains former MIT postdoc Ian Wong. “We have only just started to understand some of the unique physical and chemical processes that occur in their atmospheres – processes that have no analogs in our own solar system.”
Newsweek reporter Robert Lea writes that astronomers from MIT and elsewhere have found evidence of a large planetary collision that stripped the atmosphere from a planet. “While astronomers have long believed these kinds of collisions are common throughout the Universe, this is the first time that they have spotted evidence of one that stripped an atmosphere in such a way around a distant star,” writes Lea.
A new study co-authored by MIT researchers presents the first evidence that a distant planet had its atmosphere partially blown away by a large impact, reports Charles Choi for Space.com. "I think a really critical implication is that the gas that is released in the aftermath of a giant impact can last for a long time, and it can affect the way the system evolves long-term," explains graduate student and lead author Tajana Schneiderman.
Prof. Sara Seager speaks with Washington Post reporter Timothy Bella about the search for exoplanets and the James Webb Telescope. “I just remember seeing the stars and being overwhelmed by the beauty and the vastness and the mysteriousness of it,” recalled Seager, of a camping trip with her father that helped inspire her interest in space. “There’s something almost terrifying about it at the same time as it being so beautiful, because yeah, it’s so unknown, and it seems like it goes on forever.”
Postdoc Tansu Daylan speaks with CNN reporter Ada Wood about his work mentoring two high school students, and their discovery of four new exoplanets. "When it comes to studying by comparison — that is, studying the atmospheres of planets beyond the solar system around sun-like stars — this is probably one of the best targets that we will ever get," says Daylan.
Two high school students and their mentor, MIT postdoc Tansu Daylan, have discovered four new exoplanets located about 200 light years from Earth, reports Nora McGreevy for Smithsonian. The students were participating in the Student Research Mentoring Program, which pairs young astronomers with scientists at MIT and Harvard. “[The students] are so good at finding things that may skip your eyes, basically. It’s fun. And I really like the exchange of ideas,” Daylan adds.
Mashable spotlights how two high school students, who were part of Student Research Mentoring Program (SRMP) at the Harvard-Smithsonian Center for Astrophysics (CfA) and MIT, have discovered four new exoplanets. “Both the students took guidance from mentor Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, and helped the students study and analyze data from the Transiting Exoplanet Survey Satellite (TESS).”
Fox News reporter Chris Ciaccia writes that a team of astronomers, including MIT researchers, has found an exoplanet that has a 3.14-day orbit. “The ‘pi planet’ known as K2-315b is relatively close to Earth at 186 light-years away,” writes Ciaccia.
MIT researchers have discovered an Earth-sized planet, named K2-315b, which is being referred to as the “pi planet” for its 3.14 day orbit, reports Allison Gasparini for Forbes. “Having planets like K2-315b will help us to further understand the diverse planet bodies out there,” says graduate student Prajwal Niraula.
Prof. Sara Seager speaks with Judi Ketteler of The Boston Globe about her new book, “The Smallest Light in the Universe.” Seager shares that the night sky still conjures up the same feelings of "awe and wonder,” that she felt as a child. “The only difference is, I wonder about the planets around those stars. I wonder if anyone’s on those looking back at us from their planet.”
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.”
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.”
