Scientists from LIGO and Virgo have detected the largest collision between two black holes to date, which appears to have created an “intermediate-mass” black hole, reports Loren Grush for The Verge. Intermediate-mass black holes, “are really the missing link between [black holes with] tens of solar masses and millions,” says Prof. Salvatore Vitale. “It was always a bit baffling that people couldn’t find anything in between.”
Gizmodo reporter George Dvorsky writes about how researchers from MIT and other institutions have detected the corona of a supermassive black hole disappearing and then reappearing. Dvorsky writes that their findings suggest this “strange episode was caused by a runaway star.”
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.”
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.
Don Sousa, who coordinates shipments for the MIT Haystack Observatory, speaks with Atlantic reporter Marina Koren about the complex process of shipping petabytes of data from telescopes around the world to compile the first image of a black hole. Koren writes that for Sousa, “the photo is the culmination of years’ worth of effort by astronomers and shipping experts alike.”
Writing for WBUR, Prof. Marcia Bartusiak examines the significance of astronomers capturing the first image of a black hole, and how information gathered from studying black holes could provide insights into the origins of our universe. “Continued efforts like the Event Horizon Telescope project will provide astronomy’s next steps in separating fantasy from reality,” writes Bartusiak.
Postdoctoral fellow Kazunori Akiyama speaks with Science News reporter Emily Conover about his work translating the data compiled from eight observatories around the world into the first image of a black hole. “I was really happy, really excited,” says Akiyama of his emotions after seeing the first rendering of a black hole.
Haystack research scientist speaks with Lowell Sun reporter Alana Melanson about how scientists at the Haystack Observatory made key contributions to creating the first-ever image of a black hole. “It's enormous volumes of data coming at you very, very fast -- much faster than you can record on a single hard drive,” says Fish of the vast quantities of data processed at Haystack to develop the image.
WCVB-TV’s Rhondella Richardson visits the MIT Haystack Observatory to learn more about how researchers there helped process the data that was compiled to produce the first image of a black hole. “It really does look exactly like what we expected it to, based on Einstein’s model of relativity,” explains Michael Hecht, Haystack’s associate director for research management. “There’s still a sense of awe.”
