ALMA (Atacama Large Millimetre/Submillimetre Array) 18 Mar 2019, 18:42 UTC Scientists from the RIKEN Cluster for Pioneering Research in Japan,the Chalmers University of Technology in Sweden,and the University of Virginia in the USA and collaborators used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system.
ASTRON 18 Mar 2019, 08:07 UTC An international team of astrophysicists observed for the first time that the jet of a quasar is less powerful on long radio wavelengths than earlier predicted. This discovery gives new insights in the evolution of quasar jets. They made this observation using the international Low Frequency Array (LOFAR) telescope, that produced high resolution radio images of quasar 4C+19.44 located over 5 billion light-years from Earth.
NASA's Goddard Space Flight Center 15 Mar 2019, 11:30 UTC This Hubble picture shows Messier 28, a globular cluster in the constellation of Sagittarius (the Archer), in jewel-bright detail. It is about 18,000 light-years away from Earth.
NASA's Goddard Space Flight Center 14 Mar 2019, 17:00 UTC This trio of images acquired by NASA’s OSIRIS-REx spacecraft shows a wide shot and two close-ups of a region in asteroid Bennu’s northern hemisphere. The wide-angle image (left), obtained by the spacecraft’s MapCam camera, shows a 590-foot (180-meter) wide area with many rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks. The two closer images, obtained by the high-resolution PolyCam camera, show details of areas in the MapCam image, specifically a 50-foot (15 meter) boulder (top) and the regolith pond (bottom). The PolyCam frames are 101 feet (31 meters) across and the boulder depicted is approximately the same size as a humpback whale.
NASA's Chandra X-ray Observatory 14 Mar 2019, 16:00 UTC Fancy a cup of cosmic tea? This one isn't as calming as the ones on Earth. In a galaxy hosting a structure nicknamed the "Teacup," a galactic storm is raging.
ESA Space Science 14 Mar 2019, 09:15 UTC This image covers a portion of the wall-terrace region of the 100 km-wide Columbus Crater located within Terra Sirenum in the southern hemisphere of Mars. The image was taken by the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter on 15 January 2019.
NAOJ Top News 13 Mar 2019, 15:01 UTC A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the distant universe, from an epoch when the universe was less than 10 percent of its present age. This finding was made by using the wide-field camera Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope. The discovery increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common SMBHs are early in the universe’s history. In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.
NASA's Jet Propulsion Laboratory News and Features 12 Mar 2019, 21:42 UTC Over 29 days last spring, NASA's Mars Exploration Rover Opportunity documented this 360-degree panorama from multiple images taken at what would become its final resting spot in Perseverance Valley. Located on the inner slope of the western rim of Endurance Crater, Perseverance Valley is a system of shallow troughs descending eastward about the length of two football fields from the crest of Endeavor's rim to its floor.
