Prof. Rainer Weiss speaks with Marco Werman of PRI about his childhood, what inspired his interest in science, and black holes. "One of the dreams I would have, had Einstein been still alive, is to tell him about this,” said Weiss, of the successful detection of gravitational waves. “I would have loved to have seen what he would have thought.”
Lisa Grossman writes for New Scientist that a new report from the National Academies urges the U.S. to “get back on the gravitational-wave hunting horse” in support of a space-based detector. MIT Prof. Jacqueline Hewitt, who chaired the report panel, also touted exoplanets research. “The government is getting its money’s worth in terms of the resources it’s been investing in support for scientists,” says Hewitt.
A National Academies panel chaired by MIT Prof. Jacqueline Hewitt “says the United States should rejoin a partnership with the European Space Agency... to study gravitational waves in space,” reports Daniel Clery for Science. “The community very much wants to see LISA [the Laser Interferometer Space Antenna] go forward,” explains Hewitt.
Science reporter Adrian Cho profiles Prof. Emeritus Rainer Weiss, exploring everything from his decades-long dedication to the search for gravitational waves to his reputation as a mentor. Prof. Emeritus Robert Birgeneau notes that Weiss was respected for “his passion and his courage in going after really important physics.”
Amina Khan of The Los Angeles Times writes that a team of scientists, led by postdoc Julien de Wit, has conducted an atmospheric study of two Earth-sized exoplanets and found that they are rocky and have thin atmospheres. The findings “lend growing support to the idea that such planets might potentially be friendly to life.”
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.”
