NASA’s Transiting Exoplanet Survey Satellite (TESS), which is “the brainchild of researchers at the Massachusetts Institute of Technology,” hopes to “identify at least 50 rocky exoplanets—Earth-size or bigger,” that will eventually be scrutinized by a larger telescope that is launching in 2022, writes Daniel Clery for Science. “This is the finder scope,” explains research scientist and TESS principal investigator George Ricker.
Launching next month, the TESS satellite “is NASA's next mission in the search for exoplanets,”writes Ashley Strickland for CNN. “We expect TESS will discover a number of planets whose atmospheric compositions, which hold potential clues to the presence of life, could be precisely measured by future observers,” said George Ricker of the MIT Kavli Institute, who is a principal investigator on the mission.
Dennis Overbye of The New York Times speaks with Prof. Sara Seager and senior research scientist George Ricker about the future of the Transiting Exoplanet Survey Satellite, or TESS. The mission, led and operated by MIT, is preparing to orbit Earth for two years in search of other planets.
Research led by Dheeraj Pasham, a postdoc at MIT's Kavli Institute, provides evidence “that black holes feed on passing stars then eject energetic jet streams,” writes Laney Ruckstuhl for The Boston Globe. “Such black hole jet streams can have large implications for the galaxies they enter. Pasham said they can regulate the growth of a galaxy because of their energy levels."
Meghan Bartels of Newsweek discusses a discovery from the Kavli Institute of the first tidal disruption flare or “jet” that’s been produced due to a supermassive black hole consuming a star in space. “This is telling us the black hole feeding rate is controlling the strength of the jet it produces,” NASA Einstein Postdoc Fellow and lead researcher Dheeraj Pasham said.
Brooks Hays for UPI highlights research led by postdoc Dheeraj Pasham from MIT's Kavli Institute, that has captured the rare occurrence of “radio signals produced by a black hole devouring a star.” “This is the first time we've seen a jet that's controlled by a feeding supermassive black hole,” explained Pasham.
Mary Beth Griggs writes for Popular Science about a new Nature study where researchers have identified cold hydrogen dating back to 180 million years post-big bang. “Some of the radiation from the very first stars is starting to allow hydrogen to be seen,” says Alan Rogers of the Haystack Observatory.
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.
Hydrogen detected via radio waves by MIT researchers indicates the presence of stars 180 million years after the Big Bang, reports Will Dunham of Reuters. The radio waves also indicate that the universe was likely twice as cold as was previously believe, which Research Affiliate Alan Rogers suggests “might be explained by interaction between the gas and dark matter.”
Los Angeles Times writer Amina Khan examines the planets that surround dwarf star TRAPPIST-1 – highlighting that most planets near earth’s size are likely to be rocky. “It will be really fascinating when we get to dive into the atmosphere of each of these planets and see how different or similar they are," said postdoc Julien de Wit.
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.
Prof. Nergis Mavalvala speaks with Massive reporter Prabarna Ganguly about her work engineering high-precision laser beams to detect signals from deep space, the long hunt for gravitational waves and her hopes for future generations of scientists. Ganguly writes that Mavalvala is, “one of the stalwarts in a long, arduous, and deeply human discovery of faraway perturbations rippling through the universe.”
UPI reporter Brooks Hays writes that an international team of astronomers, including MIT Prof. Saul Rappaport, has detected comets outside the Milky Way. “The distant ice balls, roughly the size of Halley's Comet, were spotted orbiting a small star 800 light-years from Earth. They were documented using transit photometry,” Hays explains.
Wired reporter Abigail Beall explores the science behind the successful detection of two colliding neutron stars. "It immediately appeared to us the source was likely to be neutron stars, the other coveted source we were hoping to see—and promising the world we would see," says MIT’s David Shoemaker, spokesperson for the LIGO Scientific Collaboration.
Boston Globe reporter Eric Moskowitz explores the significance of the first detection of two colliding neutron stars using gravitational wave detectors and telescopes. Moskowitz notes that the discovery offers, “so many immediate and long-term rewards that researchers struggled to pick their favorite part.” Senior Research Scientist Erik Katsavounidis explained that, “It’s like getting a kid in the candy store and telling them to choose.”
