Physicists have built a pair of microscopic drums and, through quantum entanglement, have found they beat together in perfect synchrony. Plus, dwarf galaxies, China’s Zhurong rover, the East African Rift, and more about ice giants.
Two new studies are attempting to solve a couple of big puzzles in astrophysics: Is the Hubble constant actually constant? And why do galaxies have flat rotation curves? Plus, a young star’s circumstellar disk, the search for stellar-mass black holes, magnesium in the deep waters of Neptune and Uranus, and an interview with PSI scientist David Horvath regarding possibly active volcanism on Mars.
Monday was the first day of the Lunar and Planetary Science Conference, and we are going to spend at least the next two weeks sharing as much science as possible. The conference is taking place virtually this year, and of course, Mars is the big focus. Plus icy worlds, volcanic worlds, and exoplanets, and we’re bringing you a little of everything.
Scientists using Hubble to track storms on Neptune found that a current storm has reversed direction and possibly shed a fragment. Plus, an update on Hayabusa2’s sample return, a non-technological radio emission from an exoplanet, This Week in Sky Watching, and more!
Today’s top story brings us 39 new gravitational wave detections of black holes and neutron stars, courtesy of the LIGO and VIRGO detectors. Also, it’s Titan’s turn for interesting molecules in the atmosphere, and researchers examined impact craters to see what might lie beneath Titan’s surface. Plus, Hayabusa2’s impact on Ryugu and an updated origin story for Jupiter and Saturn.
