MIT astronomers have used light echoes from X-ray bursts to try to map the environment around black holes, reports Dennis Overbye for The New York Times. Prof. Erin Kara then worked with education and music experts to transform the X-ray reflections into audible sound. “I just love that we can ‘hear’ the general relativity in these simulations,” said Kara.
CNN reporter Ashley Strickland writes that MIT astronomers developed an automated search tool and were able to “pin down the locations of eight rare pairings of black holes and the stars orbiting them, thanks to the X-ray echoes they release.”
Inverse reporter Charles Q. Choi writes that MIT astronomers have observed what appears to be the most tightly coupled black widow binary yet. "The one thing I know for sure is we really have never seen anything quite like this object,” says postdoctoral fellow Kevin Burdge, “and that there is probably a lot more to learn from it and other similar objects that I am finding right now, and that's what has me so excited about these."
MIT astronomers have detected what appears to be a black widow binary with the shortest orbital period ever recorded, reports Becky Ferreira for Vice. “It behaves exactly like a black widow in many, many ways,” says postdoctoral fellow Kevin Burdge, “but it also does a few new things that we've never seen before in any known black widow.”
Vice reporter Becky Ferreira writes that MIT researchers developed a new system, called the Reverberation Machine, to detect the echoes from eight new echoing black hole binaries. “These echoes offer a rarely seen glimpse into the otherworldly surroundings of stellar-mass black holes, which are about five to 15 times the mass of the Sun,” writes Ferreira.
MIT researchers have detected eight echoing black hole binaries in the Milky Way and then converted the black hole X-ray emissions into sound waves, reports Isaac Schultz for Gizmodo. The researchers developed a new tool, dubbed the Reverberation Machine, which “combed satellite data from NICER, a telescope aboard the International Space Station that studies X-ray emissions from sources like black holes and neutron stars, including a weird type of emission known as an ‘echo.’”
Researchers from MIT and Arizona State University are working on a mission that “could resolve unanswered questions about ancient planetesimal cores floating in space – and go back in time to study Earth’s own formation,” reports Megan I. Gannon for Popular Science.
Ariel Ekblaw, director of MIT’s Space Exploration Initiative, speaks with Denise Chow at NBC News about the increased opportunities in space and satellite research in recent decades. “If you were a Ph.D. student in the prior domain, it could have taken years and you may never have had a chance to actually deploy your research on the International Space Station,” said Ekblaw. “But now, within four to six years, we might do three or four missions to the International Space Station within that time.”
To celebrate the list of known exoplanets topping 5,000, New York Times reporter Becky Ferreira spoke with astronomers, actors and astronauts about their favorite exoplanets or exoplanetary systems. “TOI-1233 is an outstanding planetary system with its high number of transiting planets, sunlike host star and its proximity to the solar system,” says postdoc Tansu Daylan of the system he detected along with two high school students he was mentoring.
Researchers from MIT and other institutions have developed a new simulation that illuminates how stars formed in the early universe, reports Martin Finucane for The Boston Globe. “It was a neutral, dark cosmos that became bright and ionized as light began to emerge from the first galaxies,” explains Aaron Smith, a NASA Einstein Fellow in MIT’s Kavli Institute for Astrophysics and Space Research.
MIT researchers have developed a new simulation of the early universe, shedding light onto the period when the first stars were formed, reports Audrey Carleton for Vice. “Using existing models of the early universe and of cosmic dust, matched with new code created to interpret how light and gas interacted with one another, they created a visual depiction of the growth of the universe,” writes Carleton.
NASA astronaut Raja Chari SM ’01 and European Space Agency (ESA) astronaut Matthias Maurer performed a spacewalk to help maintain the crucial cooling systems aboard the International Space Station (ISS), reports Ed Browne for Newsweek. “Spacewalks are an important part of life on the space station,” writes Browne. “Also called an extravehicular activity (EVA), a spacewalk is when an astronaut or cosmonaut gets out of the ISS whilst wearing a pressurized and oxygenated space suit that protects them from the vacuum of space.”
Prof. Sara Seager has been awarded one of NASA’s Innovative Advanced Concepts (NIAC) awards, which will help fund her project aimed at sending an orbiter that deploys an inflatable probe to Venus, as part of an effort to search for habitability or signs of life, reports Ramin Skibba for Wired. “This search for signs of life on Venus has been around for a long time, and now the stars are aligned to start taking it seriously,” says Seager.
Prof. Nergis Mavalvala, dean of the MIT School of Science, speaks with Nobel Peace Prize laureate Malala Yousafzai about what inspired her love of science, how to inspire more women to pursue their passions and her hopes for the next generation of STEM students. “Working and building with my hands has always been something I’ve enjoyed doing,” says Mavalvala. “But I’ve also always been interested in the fundamental questions of why the universe is the way it is. I couldn’t have been more delighted when I discovered there was such a thing as experimental physics.”
MIT astronomers have observed the dark side of a football-shaped exoplanet known as WASP-121b and found that it may have metal clouds made up of iron, corundum, and titanium, reports Isaac Schultz for Gizmodo. “The vastly different temperatures on either side of the planet make a dynamic environment for the various molecules floating around the atmosphere,” writes Schultz. “In the daytime, water gets ripped apart by the nearly 5,000° Fahrenheit heat and blown to the night side of the planet by 11,000-mile-per-hour winds.”
