This April, NASA will launch the Transiting Exoplanet Survey Satellite, or TESS, which will measure the masses of at least 50 “potentially Earth-like worlds,” writes Irene Klotz for Scientific American. “We’re finding the particular star that actually potentially hosts an exoplanet around it,” said senior research scientist George Ricker, the lead scientist on TESS.
Prof. Sara Seager speaks to Guy Raz of NPR’s TED Radio Hour about the search for habitable planets outside of our solar system. “We know that there are lots of planets in their star's habitable zones that gives us confidence, but we still need a lot more information,” says Prof. Seager.
Boston Globe reporter Marin Finucane writes that with the help of around 10,000 citizen scientists, a team of astronomers has discovered five planets outside our solar system. “It’s exciting because we’re getting the public excited about science, and it’s really leveraging the power of the human cloud,” says Prof. Ian Crossfield of the discovery.
CBC News reporter Michael MacDonald spotlights the work of Prof. Sara Seager, who he calls a “certified rock star” in her field, describing everything from her interest in astronomy as a young child to her current search for exoplanets and alien life. McDonald writes that, “ultimately, her research could help answer some of the biggest questions facing humankind.”
Prof. Sara Seager speaks with WGBH’s Edgar Herwick about the search for life on other planets, following the discovery of seven Earth-sized exoplanets. "The first thing we’re gonna look for is water vapor in the atmosphere," Seager explains. “If there’s water, we want to look and see if there are gasses that don’t belong that might be produced by life."
Postdoc Julien de Wit speaks with Boston Herald reporter Marie Szaniszlo about the discovery of seven Earth-like planets. De Wit, who is leading the effort to study the planets’ atmospheres, explains that “this is the first time that we’ve found so many small planets — each potentially habitable — around the same star, a star that’s close to us.”
Postdoc Julien de Wit speaks with NPR reporter Nell Greenfieldboyce about the discovery of seven exoplanets that could harbor the conditions necessary to sustain liquid water. Greenfieldboyce reports that de Wit explained that the planets have a “‘winning combination’ of being temperate, Earth-size and ideally suited for follow-up observations with telescopes to analyze their atmospheres.”
An international team of scientists, including astronomers from MIT, has discovered seven Earth-sized planets, reports Sarah Kaplan for The Washington Post. Julien de Wit, a postdoc at MIT who is leading the study of the planets’ atmospheres, explains that repeated observations of the planets, “lifted the veil on the architecture of the system.”
Washington Post reporter Sarah Kaplan writes that a new study by MIT postdoc Julien de Wit provides evidence of a star that pulses when in proximity to its orbiting planet. De Wit and his colleagues found that the “star's brightness oscillated according to the exact rhythm of its planet's orbit.”
MIT astronomers have discovered a star that pulsates in response to an exoplanet orbiting around it, reports Brooks Hays for UPI. The findings “contradict the wisdom of most stellar models, which suggest planets can't influence their host stars in such a manner,” Hays explains.
Postdoc Jennifer Burt speaks with Boston Globe reporter Andrew Grant about a new database of nearby stars that has been made publically available. “This could be a great way to get undergrad and high school students involved in science,” Burt explains. “We’re inspiring the next generation of scientists and that’s awesome.”
In an in-depth piece for The New York Times Magazine, Chris Jones spotlights Prof. Sara Seager, exploring her quest for an Earthlike exoplanet. Jones writes there has been an explosion of knowledge about exoplanets in part because of “Seager’s pioneering theoretical work in using light to study the composition of alien atmospheres.”
In an article for Quartz, Prof. Sara Seager speculates about what it might be like to visit the recently discovered Earth-like planet dubbed Proxima Centauri. Seager writes that “the most fascinating aspect to me is that on the planet, the alien sun would be in the same place in the sky at all times.”
New findings from EAPS postoc Julien de Wit shows that two previously discovered exoplanets 40 light years from Earth have rocky surfaces, which “represent a unique opportunity to go looking for conditions that would favor life,” writes Rachel Feltman for the The Washington Post.
TIME reporter Jeffrey Kluger writes that researchers have discovered three potentially habitable planets. Kluger explains that the researchers observed the planets orbiting an ultracool dwarf star “at a distance at which water—the must-have ingredient for life as we know it—could exist in liquid form.”
