EAPS postdoc Julien de Wit and his colleagues have analyzed the atmospheres of two potentially habitable exoplanets, reports Alan Yuhas for The Guardian. Based off their observations, de Wit explains that the atmospheres of the planets are probably similar to a “terrestrial planet like Mercury, Venus, Mars and Earth.”
A double transit of two Earth-sized exoplanets allowed an international team of scientists, led by postdoc Julien de Wit, to conduct an atmospheric analysis, writes Vivian Wang for The Boston Globe. The researchers found that “the planets have rocky, rather than gaseous, terrain, and compact, rather than loose, atmospheres — all further indication that they are potentially habitable.”
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.
Ryan Mandelbaum of Popular Science speaks with David Shoemaker, who leads MIT’s LIGO Lab and Advanced LIGO, about the second successful detection of gravitational waves. "It’s wonderful," says Shoemaker. "It’s so different from the first one ... but its importance is no less."
Boston Globe reporter Eric Moskowitz writes that scientists have been able to detect gravitational waves for the second time. “It’s a wondrous thing,” said David Shoemaker, who leads the MIT lab that helped build the detectors. “Three months apart, 1.4 billion years ago, these two events happened at two different places in the sky.”
Scientists have observed a second pair of black holes colliding using the twin detectors of the Laser Interferometer Gravitational Wave Observatory (LIGO), reports Dennis Overbye for The New York Times. Overbye writes that LIGO provides “a way of hearing the universe instead of just looking at it.”
For the second time, scientists have detected gravitational waves produced by the collision of two black holes, reports Irene Klotz for Reuters. “We are starting to get a glimpse of the kind of new astrophysical information that can only come from gravitational-wave detectors,” says David Shoemaker, who leads Advanced LIGO.
In an article for New Scientist, Lisa Grossman writes that for the second time the Laser Interferometer Gravitational Wave Observatory (LIGO) has detected gravitational waves. “This gives us confidence,” says MIT research scientist Salvatore Vitale. “It was not just a lucky accident. Seeing a second one tells us clearly that there is a population of black holes there.”
Prof. Rainer Weiss speaks with Clara Moskowitz of Scientific American about why he is excited by the public’s reaction to the successful detection of gravitational waves. Weiss says that for him one of the most gratifying things is if he and his colleagues can help “make the argument that science is something everybody gets benefit from.”
Washington Post reporter Rachel Feltman writes that astronomers have observed a black hole consuming cold gas. Feltman notes that “this is the first time a black hole has been seen eating such a refreshing meal: Scientists previously had only observed black holes eating slow, steady meals of hot gas shed by the spiraling galaxies they call home.”
TIME reporter Jeffrey Kluger writes that MIT researchers have designed an algorithm to produce an image of a black hole. Kluger explains that the algorithm will allow researchers “visualize the event horizon that surrounds the black hole at the center of our own galaxy.”
A team of astronomers, including MIT Prof. Michael McDonald, has observed a black hole feasting on cold gas. BBC News reports that the team “discovered a supermassive black hole and saw clouds speeding towards it at 800,000 mph. The observation supports a theory black holes feed on clouds of cold gas.”
MIT graduate student Katie Bouman speaks with Ben Johnson of Marketplace about the algorithm she and her colleagues developed to allow people “to see the first image of a black hole.” Johnson notes the algorithm has uses beyond space exploration and could also potentially be used for MRI imaging.
MIT researchers have developed a new algorithm to compile data gathered by the Event Horizon Telescope and create an image of a black hole, reports James Griffiths for CNN. The algorithm will “fill in the gaps and filter out the interference and noise caused by our own atmosphere,” Griffiths explains.
Washington Post reporter Brian Fung writes that MIT researchers have developed an algorithm to create images of black holes by compiling data from radio telescopes around the world. Fung writes that the algorithm “could give us the first true images of a celestial phenomenon that, for decades, we've left to artists to imagine and describe with pictures.”
