9 Apr 2021, 19:56 UTC So, you want to find dark matter, but you don’t know where to look? A giant planet might be exactly the kind of particle detector you need! Luckily, our solar system just happens to have a couple of them available, and the biggest and closest is Jupiter. Researchers Rebecca Leane (Stanford) and Tim Linden (Stockholm) released a paper this week describing how the gas giant just might hold the key to finding the elusive dark matter. Next Previous

NASA's Goddard Space Flight Center 16 Apr 2021, 16:00 UTC NASA’s Parker Solar Probe mission has given scientists the first complete look at Venus’ orbital dust ring, a collection of microscopic dust particles that circulates around the Sun along Venus’ orbit. Though earlier missions have made some observations of Venus’ orbital dust ring, Parker Solar Probe’s images are the first to show the planet’s dust ring for nearly its entire 360-degree span around the Sun.
NASA's Goddard Space Flight Center 15 Apr 2021, 18:00 UTC Like boot prints on the Moon, NASA's OSIRIS-REx spacecraft left its mark on asteroid Bennu. Now, new images — taken during the spacecraft's final fly-over on April 7 — reveal the aftermath of its historic encounter with the asteroid.
NASA's Chandra X-ray Observatory 14 Apr 2021, 13:00 UTC In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). This supermassive black hole weighs 6.5 billion times the mass of the sun and is located at the center of M87, about 55 million light-years from Earth.
NASA's Goddard Space Flight Center 13 Apr 2021, 14:00 UTC NASA’s Nancy Grace Roman Space Telescope will provide an unprecedented window into the infrared universe when it launches in the mid-2020s. One of the mission’s planned surveys will use a quirk of gravity to reveal thousands of new planets beyond our solar system. The same survey will also provide the best opportunity yet to definitively detect solitary small black holes for the first time. Formed when a star with more than 20 solar masses exhausts the nuclear fuel in its core and collapses under its own weight, these objects are known as stellar-mass black holes.
NASA's Goddard Space Flight Center 9 Apr 2021, 13:00 UTC The luminous heart of the galaxy M61 dominates this image, framed by its winding spiral arms threaded with dark tendrils of dust. As well as the usual bright bands of stars, the spiral arms of M61 are studded with ruby-red patches of light. Tell-tale signs of recent star formation, these glowing regions lead to M61’s classification as a starburst galaxy.
NASA's Goddard Space Flight Center 8 Apr 2021, 18:00 UTC A global science collaboration using data from NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.

Universe Today 15 Apr 2021, 21:34 UTC Researchers at the Australian National University (ANU) are finding new uses for the laser-based technology that sharpens telescope imagery – called adaptive optics – and it just might help mitigate the world’s growing space debris problem. Purpose-built lasers could give derelict satellites a slight ‘push’ of photons, imparting just enough energy to change the debris’s orbit and prevent an impending collision.
