Popular Science names “Advanced LIGO by MIT and CalTech (2016)” as one of the 20 best tech discoveries of the last decade. “LIGO has captivated people the world over, making them curious about esoteric subjects like the nature of space and origin of, well, everything.”

The Economist explores how the Transiting Exoplanet Survey Satellite (TESS), an MIT-led NASA mission, has identified a number of new exoplanets and, in the process, helped astronomers and scientists unearth new details about our universe. This latest discovery, according to The Economist, “will help answer some of the biggest questions in the rapidly growing science of exoplanetology.”

A new MIT study shows that NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered three new exoplanets in a system known as TOI-270. “The newly discovered exoplanets are some of the smallest and closest ever found,” reports Ashley Strickland for CNN. “All three planets are similar in size, which is very different from our own solar system filled with extremes.”

Postdoc Maximilian Günther is the lead author on a paper showing that NASA’s TESS satellite has discovered three new exoplanets. “The exoplanets are of a type that does not exist in our solar system, being between the Earth and Neptune in size,” writes Daniel Clery for Science.  “That makes the closely packed system, known as TOI-270, a good bet for answering long-standing questions about how such ‘super-Earths’ or ‘mini-Neptunes’ form.”

TESS, an MIT-led NASA mission, has discovered two gaseous exoplanets and one rocky exoplanet within a system known as TOI-270, reports New Scientist. “TOI-270 will soon allow us to study this ‘missing link’ between rocky Earth-like planets and gas-dominant mini-Neptunes, because here all of these types formed in the same system,” says postdoc Maximilian Günther, lead author of a paper on the new system. 

The New York Times’ Dennis Overbye reports on a paper from MIT, which shows that NASA’s planet hunting satellite TESS has discovered three new exoplanets in a system 73 light-years from Earth known as TOI-270. “TOI-270 is a true Disneyland for exoplanet science because it offers something for every research area,” says postdoc and lead author Maximilian Günther. “It is an exceptional laboratory for not one, but many reasons.”

MIT researchers have found that the universe’s first stars exploded in an aspherical manner, spewing heavy metals into the universe, reports Rachel Cromwell for Scientific American. “This is a beautiful paper,” says Volker Bromm of the University of Texas at Austin, noting that this type of stellar sleuthing is possible only with very high-quality data.

Newsweek reporter Aristos Georgiou writes that MIT researchers have found that explosions of our universe’s first stars sent the first heavy elements into neighboring galaxies. “These elements provided the raw material for the formation of a second generation of stars, some of which survive to this day,” Georgiou explains.

Boston Globe reporter Laura Krantz visits MIT’s Haystack Observatory to learn more about the place where scientists played a key role in developing the first image of a black hole and created a supercomputer used to compile the image. Krantz notes that researchers at Haystack also study the Earth, not-far-away planets, and stars, and are creating devices to track the decay of icebergs.

Sky and Telescope editor Monica Young speaks with WBUR about how scientists from the LIGO and Virgo gravitational wave observatories, including MIT researchers, may have detected a black hole colliding with a neutron star. Young explains that upgrades made to both observatories should enable investigation of not only individual cosmic events, but also the study of neutron stars and black holes as populations.

Adrian Cho of Science magazine writes that the possible black hole-neutron star merger spotted by LIGO and Virgo would be a “gem for scientists,” but work remains to confirm the signal. Prof. Salvatore Vitale, a LIGO member from MIT, tells Cho: “If you ask me, ‘Would you bet a coffee, your car, or your house on this?’ I would say, ‘I’d bet your car.’”

Gizmodo reporter Ryan Mandelbaum explores the five potential gravitational wave detections made by the LIGO and Virgo observatories in the last month. Prof. Salvatore Vitale explained that the possible detection of a black hole colliding with a neutron star could provide scientists with a better way to measure how quickly the universe is expanding.

“LIGO/VIRGO has opened up its notification process to the public,” explains Ars Technica reporter John Zimmer. “In short, anyone who’s interested can find out what LIGO is seeing within a day of when the LIGO scientists themselves do.”

 

The LIGO and Virgo gravitational wave detectors have identified five new cosmic events since resuming operations last month, reports Sarah Lewin for Space.com. “The most exciting thing of the beginning of O3 [this third observation round] is that it's clear we are going from one event every few months to a few events every month," explains Prof. Salvatore Vitale.

Prof. Frank Wilczek writes for The Wall Street Journal about how the first image of a black hole could help scientists gain a better understanding of how galaxies form and evolve. “To a thinking mind, the image reflects the glory of understanding, and to an alert imagination it opens new portals into space, time and deep history,” writes Wilczek.
