Scientists from MIT and other institutions have detected the longest-lasting and most regular radio signal in the night sky, reports Jamie Carter for Forbes. “Scientists think that the radio signal may be coming from a neutron star—what remains of the collapsed core of a giant star after it’s exploded as a supernova,” explains Carter.
Astronomers from MIT and elsewhere have discovered radio signals in space that they believe to be coming from a neutron star, reports Tim Marcin for Mashable. “Using the CHIME (Canadian Hydrogen Intensity Mapping Experiment) radio telescope, astronomers noticed a strange FRB, or radio burst, from a far-off galaxy billions of light-years from Earth.”
Graduate students Mehtaab Sawhney and Ashwin Sah were among the four mathematicians to demonstrate “it’s always possible to build such a hypergraph as long as you have enough nodes,” a 50-year-old proof first proposed by Paul Erdős, reports Leila Sloman for Quanta Magazine.
A team of astronomers have identified a mysterious radio burst from a far-away galaxy, reports Wyatte Grantham-Philips for USA Today. “Imagine a very distant galaxy. And sometimes, some huge explosions happen that emit huge blasts of radio waves,” explains Daniele Michilli, who led the study and is a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research. “We don’t know what these explosions are, (but) they are so powerful that we can see them from across the universe.”
Postdoctoral scholar Daniele Michilli and members of the CHIME/FRB Collaboration have discovered radio bursts from a galaxy billions of light-years away, reports Ashley Strickland for CNN. “The research team will continue to use CHIME to monitor the skies for more signals from the radio burst, as well as others with a similar, periodic signal,” writes Strickland, noting the work “could be used to help astronomers learn more about the rate of the universe’s expansion.”
Astronomers at MIT and elsewhere have picked up repeated radio signals from a galaxy billions of light-years away from Earth, reports Ayana Archie for NPR. “Scientists have not been able to pinpoint the exact location of the radio waves yet, but suspect the source could be neutron stars, which are made from collapsed cores of giant stars,” writes Archie.
Prof. Nikta Fakhri and her colleagues have placed hundreds of starfish embryos into salt-water tanks where they arrange themselves into honeycomb-like patterns at the water’s surface, reports Karmela Padavic-Callaghan for New Scientist. “These structures, which had never been seen before, may form because of the embryos’ swimming style and body shape,” explains Padavic-Callaghan.
Reporting for The Boston Globe, Hanna Kreuger highlights a graph documenting the atmospheric conditions of the exoplanet WASP-96b, which NASA included in its first release of images from the James Webb Space Telescope. Describing it as “perhaps the image that showcases Webb’s greatest triumph,” Krueger notes that the graph was created using an equation developed by Prof. Sara Seager. Seager and her team will use the telescope to peer into TRAPPIST-1e, an exoplanet widely considered to be potentially Earth-like and habitable, adds Krueger.
As the first images from the James Webb Space Telescope were released on Tuesday, showcasing the deepest view of the universe ever, CBS Boston spoke with Prof. Julien de Wit about the importance of the moment. “It’s groundbreaking. It’s like going from listening to the radio to suddenly being able to watch television,” says de Wit. “Further down the road, we may be able to see if planets are habitable, if some of these planets have signs of life one way or the other. There are so many things we’re going to discover thanks to it.”
Prof. Robert Simcoe and his team will receive 100 hours with the new James Webb Space Telescope to look at some of the first stars and galaxies to form after the Big Bang, reports David Bienick for WCVB. “I’m tremendously excited,” says Simcoe. “We have been preparing for this moment since 2016, knowing that we were going to have time and starting to prepare our observations, and waiting for the telescope to be ready.”
Prof. Benjamin Weiss speaks with Forbes contributor Bruce Dorminey about his latest co-authored paper detailing new paleomagnetic measurements of samples of Antarctic meteorites. “Our study shows that the solar nebula – the cloud of gas and dust out of which our solar system formed, dissipated very quickly (within less than 1.5 million years) after having lasted for 3 million years,” Weiss tells Dorminey.
MIT researchers have created Thesan, the most detailed model of the early universe to date, reports New Scientist. “Thesan shows how radiation shaped the universe from 400,000 to 1 billion years after the Big Bang,” writes New Scientist.
Shirley Ann Jackson ’68, PhD ’73, the president of Rensselaer Polytechnic Institute, is retiring, reports Kendall Ross for ABC News. “It’s about being able to walk so you can carry someone else,” says Jackson. “The most influential the positions I’ve had and the more powerful they’ve become, the more I’ve been able to help people develop open doors."
Astronomers have identified two Earth-sized exoplanets orbiting a red dwarf star 33 light years away, reports Jamie Carter for Forbes. “Both planets in this system are each considered among the best targets for atmospheric study because of the brightness of their star,” explains postdoc Michelle Kunimoto.
Graduate student Anna Ivanova and University of Texas at Austin Professor Kyle Mahowald, along with Professors Evelina Fedorenko, Joshua Tenenbaum and Nancy Kanwisher, write for The Conversation that even though AI systems may be able to use language fluently, it does not mean they are sentient, conscious or intelligent. “Words can be misleading, and it is all too easy to mistake fluent speech for fluent thought,” they write.
