Space.com reporter Mike Wall writes that researchers have calculated a supermassive black hole’s rotation rate by analyzing the X-rays it emitted after consuming a nearby star. The researchers found that “the huge black hole, known as ASASSN-14li, is spinning at least 50 percent the speed of light.”
Gizmodo reporter Ryan Mandelbaum writes that researchers determined how fast a supermassive black hole spins by measuring a star being swallowed by the black hole. Postdoctoral fellow Dheeraj Pasham explains that, “this measurement is different in the sense that we were able to measure the spin of a black hole that was dormant.”
Astronomers from MIT have detected echoes in X-ray flares emitted by a black hole consuming stellar material, writes Charles Q. Choi for Space.com. The findings “might shed light on how matter behaves not just as it falls into stellar-mass black holes,” writes Choi, “but also supermassive black holes millions to billions of times the mass of the sun.”
TechCrunch reporter Devin Coldewey writes that a team of researchers, including MIT scientists, have detected fast radio bursts (FRB) coming from a distant galaxy. Coldewey explains that the researchers used the Canadian Hydrogen Intensity Mapping Experiment radio telescope, which “points at the whole sky and chooses where to ‘look’ using software,” to identify 13 new FRBs.
Nature reporter Alexandra Witze highlights the TESS satellite’s success in uncovering new exoplanets outside our solar system. Senior research scientist George Ricker feels, “TESS works better than team members had dared to dream,” Witze writes, adding that “its four cameras can see objects 20% fainter, and focus more sharply, than originally expected.”
NASA’s MIT-led TESS mission has discovered a new exoplanet orbiting a star 53 light years from Earth, reports Mike Wall for Space.com. The “sub-Neptune” planet is “about three times bigger than Earth, which means it's likely gaseous rather than rocky,” writes Wall.
CNN reporter Ashley Strickland writes that NASA’s planet-hunting satellite TESS has discovered another exoplanet 53 light years away. Strickland explains that the exoplanet orbits “a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit.”
Prof. Max Tegmark speaks with Forbes contributor Peter High about his work trying to ensure that AI technologies are implemented in a way that is beneficial to society. “If we plan accordingly and steer technology in the right direction, we can create an inspiring future that will allow humanity to flourish in a way that we have never seen before,” says Tegmark.
NASA’s MIT-led TESS mission has discovered a new exoplanet that is about three times the size of Earth, reports Dennis Overbye for The New York Times. “There was quite some detective work involved, and the right people were there at the right time,” explains postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear.”
Verge reporter Loren Grush writes that NASA’s MIT-led TESS mission has discovered a third exoplanet. “The important thing about this system that’s especially unique is it’s near to us,” says postdoc Diana Dragomir. “What that means simply is we can study this system in detail. We can measure the mass of the planet and measure things about the star.”
Nature reporter Elizabeth Gibney spotlights Prof. Pablo Jarillo-Herrero’s discovery that graphene can act as a superconductor when twisted to a magic angle. “I haven’t seen this much excitement in the graphene field since its initial discovery,” said ChunNing Jeanie Lau, a professor at Ohio State University, of the impact of Jarillo-Herrero’s findings.
Prof. Pablo Jarillo-Herrero’s discovery that when graphene is rotated to a “magic angle” it can act as a high-temperature superconductor has been named the Physics World 2018 Breakthrough of the Year. Physics World reporter Hamish Johnston writes that the “discovery led to the development of ‘twistronics’, which is a new and very promising technique for adjusting the electronic properties of graphene.”
Researchers from the LIGO and Virgo Scientific Collaborations have detected four new black hole collisions, including the largest black hole merger detected, reports Ryan Mandelbaum for Gizmodo. Researchers have begun cataloguing “black hole collisions to tell the broader story about how often these massive crashes occur and what causes them.”
BBC News reporter Jonathan Amos writes that LIGO (operated by MIT and Caltech) and Virgo researchers have detected gravitational waves emanating from the largest black hole merger ever detected. Amos notes the discovery was announced by the collaboration as part of an “expanded catalogue” of detections that “tells us something about the probable future successes of the laser laboratories.”
Prof. Steven Barrett speaks with Forbes reporter Jeremy Bogaisky about the new plane he developed that is propelled by an ion drive, noting that he is working to embed a prolusion system within the skin of the aircraft. “There’s no reason to think long-term that airplane designs with electroaerodynamic propulsion need look at all like an airplane today,” explains Barrett.
