Using the James Webb Telescope, researchers at MIT and elsewhere are studying the potential presence of “an Earth-like atmosphere on an exoplanet for the first time,” reports Jacopo Prisco for CNN. “The planet is part of a planetary system about 40 light-years away from Earth called TRAPPIST-1,” explains Prisco.
Writing for Nature, Bruce Allen pays tribute to Prof. Emeritus Rainer Weiss, a pioneering physicist who “spearheaded the construction of the LIGO observatory to detect Einstein’s predicted ripples in space-time [and] leaves a legacy of persistence and mentorship.” Allen recalls how, decades earlier, Weiss rejoiced in a moment of discovery with him. “This is why we do science,” Weiss said. “Not for prizes or awards — that’s all nonsense. It’s for the satisfaction when something you’ve struggled with finally works.” Weiss, Allen emphasizes, was “a scientist driven by curiosity, persistence and the joy of understanding how the Universe works.”
Wall Street Journal reporter Jon Mooallem memorializes the life and work of Prof. Emeritus Rainer Weiss, from his time hacking surplus military electronics into sophisticated hi-fi receivers as a teenager to dreaming up the concept for the Laser Interferometer Gravitational-Wave Observatory (LIGO). Mooallem notes that Weiss and his LIGO colleagues’ breakthrough in achieving the first-ever detection of gravitational waves “has provided a new way of looking at the universe, of observing, through the charting of gravity waves emitted by moving objects, what was previously unobservable or unknown—a milestone that is frequently compared with Galileo’s invention of the telescope.”
Prof. Rainer Weiss, a Nobel Prize-winning physicist whose research helped “unlock the secrets of the universe,” has died at 92, reports Bryan Marquard for The Boston Globe. “He really is, by a large margin, the most influential person this field has seen. And will see,” said Caltech Prof. Emeritus Kip Thorne. Nergis Mavalvala, dean of the MIT School of Science who conducted her doctoral research with Weiss, shared that Weiss “worked on three different things, and every one of them has changed the way we understand physics and the universe.”
Prof. Emeritus Rainer Weiss, a “renowned experimental physicist” who was “integral in confirming the existence of tiny ripples in spacetime called ‘gravitational waves,’” has died, reports Robert Lea for Space.com. “Remarkably, in confirming the existence of gravitational waves, Weiss both proved Einstein right and wrong at the same time,” writes Lea. “Einstein had been convinced that these ripples in spacetime were so faint that no apparatus on Earth could ever be sensitive enough to detect them, showing just how revolutionary LIGO was.”
Tri-City Herald reporter Annette Cary memorializes the life and legacy of MIT Prof. Emeritus Rainer Weiss, a “renowned experimental physicist and Nobel laureate,” who was “key to [the] world’s first gravitational wave discovery.” At the opening ceremony in June 2022 for the LIGO Exploration Center in Hanford, Washington, Weiss relayed how life is more interesting if you have a deeper understanding of the world around you and “how science does its tricks.”
Physics World reporter Michael Banks chronicles the life and work of MIT Prof. Emeritus and gravitational wave pioneer Rainer Weiss. “Weiss came up with the idea of detecting gravitational waves by measuring changes in distance as tiny as 10–18 m via an interferometer several kilometers long,” writes Banks. “His proposal eventually led to the formation of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO), which first detected such waves in 2015.”
Professor Emeritus Rainer Weiss, a Nobel Prize-winning physicist who was honored for his work "developing a device that uses gravity to detect intergalactic events, like black holes colliding, and who helped confirm two central hypotheses about the universe,” has died at 92, reports Dylan Loeb McClain for The New York Times. In an earlier interview, Weiss reflected upon the wonder unlocked by LIGO: “With gravitational waves, you have a new way to look at [the] universe. You can see all that nature has in store. So now comes the question: What do you want to find out?”
After observing the collision between a supernova and a black hole, researchers at MIT and elsewhere are rethinking our understanding of the life and death of stars, reports Jeanine Santucci for USA Today. "One of the only reasons that we were able to make this discovery and understand how scientifically interesting it was was through the combination of researchers in machine learning and in astrophysics," says postdoctoral scholar Alex Gagliano.
With the help of a newly designed machine learning algorithm, researchers at MIT and elsewhere have spotted a “never-before-seen type of supernova that involves a nearby black hole,” reports Andrew Paul for Popular Science. “We’re now entering an era where we can automatically catch these rare events as they happen, not just after the fact,” said postdoctoral scholar Alex Gagliano. “That means we can finally start connecting the dots between how a star lives and how it dies, and that’s incredibly exciting.”
Using an AI algorithm, researchers at MIT and elsewhere have been able to identify a previously unobserved explosion in the universe that they consider a “new flavor of supernova,” reports Kasha Patel for The Washington Post. “We think that statistically we’re overdue for a supernova in our own galaxy,” says postdoctoral scholar Alex Gagliano. “There are many people that are trying to establish early warning systems so that as soon as our telescopes pick up on something unusual, we can all aim our telescopes in that location.”
Researchers at MIT have proposed that liquids, such as ionic fluids, are “what’s important for extraterrestrial habitability, and not just water,” reports Gayoung Lee for Gizmodo. If confirmed, this research would “dramatically expand what’s considered the ‘habitable zone’ among known exoplanets,” writes Lee. “By current standards, the habitable zone is defined as the band within planetary systems in which liquid water can remain stable on the surface. When it comes to life, we’re understandably biased towards water; all life as we know it depends on it.”
Graduate student Megan Masterson speaks with CBS Eye on the World hosts John Batchelor and David Livingston about her research on tidal disruption events. “These events were first theorized in the 1970s, first discovered in the 1990s with x-ray wavelengths,” explains Masterson. “But today, what James Webb is doing is allowing us to detect these events in the infrared band. And so, what we’re seeing here are previously dormant black holes that were kind of lying at the center for their galaxies doing pretty much nothing suddenly become active.”
Prof. Julien de Wit speaks with CNN reporter Ashley Strickland about asteroid 2024 YR4 and the importance of monitoring and studying asteroids to help keep Earth safe.
Ten years after scientists detected gravitational waves for the first time using the LIGO detectors, Rachel Feltman of Scientific American's “Science Quickly” podcast visits the MIT LIGO Lab to speak with Prof. Matt Evans about the future of gravitational wave research and why Cosmic Explorer, the next generation gravitational wave observatory, will help unearth secrets of the early universe. “We get to look back towards the beginning of the universe, in some sense, with gravitational waves as we look at these sources that are farther and farther away,” says Evans. “With Cosmic Explorer we’ll have not just one or two but hundreds of thousands of sources from the distant universe. So it’s a really exciting way to explore the universe as a whole by looking at this stellar graveyard.”
