NASA's Goddard Space Flight Center 19 Feb 2019, 15:30 UTC A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf — an Earth-sized remnant of a Sun-like star that has died — ringed by dust and debris. Astronomers suspect this could be the first known white dwarf with multiple dust rings.
Max Planck Institute for Radio Astronomy 19 Feb 2019, 07:00 UTC An international team of more than 200 astronomers from 18 countries including scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve.
ESA Top News 18 Feb 2019, 16:00 UTC Feeling stressed? You’re not alone. ESA’s Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov–Gerasimenko has been a key process in sculpting the comet's surface and interior following its formation.
ESA Top News 18 Feb 2019, 08:14 UTC Sitting beyond Jupiter and Saturn in our Solar System, these two planets have only been visited once by a spacecraft, albeit briefly. NASA’s Voyager 2 spacecraft swung by Uranus in 1986, and Neptune in 1989, snapping the only close-up detailed images of these distant worlds.
NASA's Goddard Space Flight Center 15 Feb 2019, 18:00 UTC Just after midnight (UTC) on February 1, 2019, the Lunar Reconnaissance Orbiter (LRO) passed nearly overhead the Chang'e 4 landing site. From an altitude of 82 kilometers the LROC Narrow Angle Camera pixel scale was 0.85 meters (33 inches), allowing a sharper view of the lander and Yutu-2 rover. At the time the rover was 29 meters northwest of the lander, but the rover has likely moved since the image was acquired. This view has close to the smallest pixel size possible in the current LRO orbit. In the future however, LROC will continue to image the site as the lighting changes and the rover roves!
NASA's Goddard Space Flight Center 15 Feb 2019, 15:00 UTC In this image, the NASA/ESA Hubble Space Telescope has captured the smoking gun of a newborn star, the Herbig–Haro objects numbered 7 to 11 (HH 7–11). These five objects, visible in blue in the top center of the image, lie within NGC 1333, a reflection nebula full of gas and dust found about a thousand light-years away from Earth.
