Astronomers at MIT and elsewhere have determined how to measure the spin of a nearby supermassive black hole using a new calculation method, reports Isaac Schultz for Gizmodo. The team “managed to deduce a supermassive black hole’s spin by measuring the wobble of its accretion disk after a star has been disrupted—a polite word for torn up—by the gigantic object,” explains Schultz. “They found the black hole’s spin was less than 25% the speed of light—slow, at least for a black hole.”
MIT researchers have developed a wearable backpack with spider-like limbs to help astronauts maintain stability in space, reports Jess Thomson for Newsweek. The new technology, called Supernumerary Robotic Limbs (SuperLimbs), “could be crucial in future missions to the moon, where gravity is only a sixth of that on Earth and astronauts may struggle to clamber up again after a fall due to their unwieldy space suits,” explains Thomson.
MIT astronomers have discovered an exoplanet that is 50% bigger than Jupiter, but still the second lightest planet ever found, with a density similar to cotton candy,” reports Leah Asmelash for CNN. The planet could provide a useful window into how puffy planets form. “The bigger a planet’s atmosphere, the more light can go through,” Prof. Julien de Wit explains. “So it’s clear that this planet is one of the best targets we have for studying atmospheric effects. It will be a Rosetta Stone to try and resolve the mystery of puffy Jupiters.”
Researchers at MIT have developed SuperLimbs, a pair of wearable robotic limbs that “can physically support an astronaut and lift them back on their feet after a fall,” reports Brain Heater for TechCrunch. “The system, which is still in the prototype phase, responds directly to the wearer’s feedback,” writes Heater. “When sitting or lying down, it offers a constructive support to help them get back up while expending less energy — every extra bit helps in a situation like this.”
Researchers from MIT and elsewhere have discovered a celestial body, which has been called “the second lightest planet ever discovered,” reports Eric Lagatta for USA Today. “The star-orbiting exoplanet outside of our solar system is about seven times less massive than Jupiter, which is why astronomers compare its low density to cotton candy,” Lagatta explains.
MIT astronomers have discovered an exoplanet with a density similar to cotton candy, reports Newsweek’s Jess Thomson. The planet, “named WASP-193b, is the second-least dense exoplanet ever found, with a density of around 0.059 grams per cubic centimeter, or 3.68 pounds per cubic foot,” Thomson explains. “This makes it about 7 times less dense than our neighboring planet Jupiter, despite being 50 percent larger in size, and about 1 percent the density of our own planet.”
An international team of astronomers, including scientists from MIT, discovered an exoplanet with an “exceedingly low density for its size,” reports Marcia Dunn for the Associated Press. The planet “is ideal for studying unconventional planetary formation and evolution,” explains Dunn.
Researchers at MIT have discovered that a previously witnessed supermassive black hole has “a smaller companion black hole zipping around it, kicking up dust every time it goes by,” reports John Wenz for Astronomy. This discovery “shakes up our thinking of what the environment at the core of the galaxy looks like,” explains Wenz. “Instead of a simple disk of matter surrounding the central black hole, steadily swirling across its event horizon, the centers of galaxies could host multiple black holes of different sizes, leading to more complex feeding behavior.”
NASA astronaut Christopher Williams PhD '12 shares his excitement over the upcoming solar eclipse with Space.com Elizabeth Howell, noting he is most excited that the celestial event will provide unique views of the sun’s outer atmosphere. Williams previously conducted radio astronomy research and helped build the Murchison Widefield Array in Australia during his time at MIT. "It was an incredible experience, because I got to both work on the cosmology and the science behind that,” recalls Williams.
Astronomers from MIT and other institutions have found that periodic eruptions from a supermassive black hole located in a galaxy about 800 million light-years from Earth could be caused by a, “second, smaller black hole slamming into a disk of gas and dust, or ‘accretion disk,’ surrounding the supermassive black hole, causing it to repeatedly ‘hiccup’ out matter,” writes Rob Lea for Space.com.
Using the James Webb Space Telescope, postdoc Rohan Naidu will be studying “some of the particularly large and red galaxies, [called little red dots,] that appear much brighter and more massive than theorists have expected galaxies at this epoch to be,” reports Jonathan O’Callaghan for Scientific American. Naidu’s “program will seek to settle the debat about little red dots once and for all,” writes O’Callaghan.
Christina “Chris” Birch PhD '15 is among NASA’s newest class of astronauts, reports Norah O’Donnell for CBS Evening News. “These new astronauts could one day be part of the team that brings the first woman and first person of color to the surface of the moon and beyond.”
Prof. Danielle Wood speaks with Science Friday guest host Sophie Bushwick about the importance of space law and the rules of space. “One of the things that is so helpful to think about when trying to define space law is the fact that space law, in many ways, happens at the national level and is negotiated at the international level, so we can say that the United States has both ratified and signed the outer space treaty which means it is also U.S law,” explains Wood. “I think that’s really key to keeping track of what it means for international law to be binding and I think that’s key to saying space law is meaningful especially because countries make it domestic law.”
Prof. Danielle Wood speaks with Science news intern Sean Cummings about how space exploration and research can benefit everyone. “It’s great to think about what it means for space to benefit everyone,” says Wood. “I think there are two dimensions to ask: I would first ask ‘how could I redesign space systems that were not designed for everyone but could be fixed to make them more effective?’ and the second would be ‘what about the new things we haven’t built yet?’”
Prof. Paulo Lozano speaks with Kaity Kline of NPR’s Morning Edition about the space stations of the future and how NASA collaborating with private companies on the development of the next iteration of the International Space Station could spur new technological advancements. “Once you have entrepreneurship and you have a commercial interest, that accelerates technology development,” says Lozano.
