NASA's Goddard Space Flight Center 16 Aug 2017, 17:00 UTC NASA’s Lunar Reconnaissance Orbiter (LRO) team invites the public to wave at the Moon on Aug. 21 as LRO turns its camera toward Earth.
ESO Top News 16 Aug 2017, 17:00 UTC Observations of “Jellyfish galaxies” with ESO’s Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly. The results appeared today in the journal Nature.
NASA Breaking News 16 Aug 2017, 13:35 UTC NASA’s newest astronaut candidates, a diverse dozen women and men, will participate in media interviews and a final news conference before training on Tuesday, Aug. 22, at the agency’s Johnson Space Center in Houston.
ESA Science & Technology 16 Aug 2017, 08:00 UTC While surveying the positions of over a billion stars, ESA's Gaia mission is also measuring their colour, a key diagnostic to study the physical properties of stars. A new image provides a preview of Gaia's first full-colour all-sky map, which will be unleashed in its highest resolution with the next data release in 2018.
NASA's Goddard Space Flight Center 15 Aug 2017, 14:20 UTC Venus looks bland and featureless in visible light, but change the filter to ultraviolet, and Earth’s twin suddenly looks like a different planet. Dark and light areas stripe the sphere, indicating that something is absorbing ultraviolet wavelengths in the planet’s cloud tops.
Lawrence Berkeley National Laboratory 14 Aug 2017, 23:29 UTC Scientists developed new theories and 3-D simulations to explain what’s at work in the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light. As much as half of the jets’ energy can escape in the form of X-rays and stronger forms of radiation. Researchers showed how two different mechanisms serve to reduce about half of the energy of these jets.
California Institute of Technology 14 Aug 2017, 22:38 UTC Astronomers using Caltech's Owens Valley Radio Observatory (OVRO) have found evidence for a bizarre lensing system in space, in which a large assemblage of stars is magnifying a much more distant galaxy containing a jet-spewing supermassive black hole. The discovery provides the best view yet of blobs of hot gas that shoot out from supermassive black holes.
