New Horizons 15 Jan 2019, 05:16 UTC This movie shows the propeller-like rotation of Ultima Thule in the seven hours between 20:00 UT (3 p.m. ET) on Dec. 31, 2018, and 05:01 UT (12:01 a.m.) on Jan. 1, 2019, as seen by the Long Range Reconnaissance Imager (LORRI) aboard NASA's New Horizons as the spacecraft sped toward its close encounter with the Kuiper Belt object at 05:33 UT (12:33 a.m. ET) on Jan. 1.
Harvard-Smithsonian Center for Astrophysics 14 Jan 2019, 19:30 UTC Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA's Chandra X-ray Observatory they have observed a jet that bounced off a wall of gas and then punched a hole in a cloud of energetic particles. This behavior can tell scientists more about how jets from black holes interact with their surroundings.
Harvard-Smithsonian Center for Astrophysics 14 Jan 2019, 14:10 UTC New research that included astronomers Luca Matra and David J. Wilner of the Center for Astrophysics | Harvard & Smithsonian has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars. The international team of astronomers used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to obtain high-resolution images of the Asteroid belt-sized disc.
ESO Top News 11 Jan 2019, 11:00 UTC Since it opened in April 2018, the ESO Supernova Planetarium & Visitor Centre has shared the wonders of the Universe with more than 55 000 visitors and captured the attention of audiences from around the globe. Now, the ESO Supernova’s extensive library of high-resolution images, stunning videos, educational texts and planetarium resources, as well as a digital version of its state-of-the-art astronomical exhibition, have been made freely available online.
ESA Top News 10 Jan 2019, 22:15 UTC ESA’s high-energy space telescopes Integral and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year.

[release] Giant pattern discovered in the clouds of planet Venus - Infrared cameras and supercomputer simulations break through Venus' veil10 Jan 2019, 01:00 UTC A Japanese research group has identified a giant streak structure among the clouds covering planet Venus based on observation from the spacecraft Akatsuki. The team also revealed the origins of this structure using large-scale climate simulations. The group was led by Project Assistant Professor Hiroki Kashimura (Kobe University, Graduate School of Science) and these findings were published on January 9 in Nature Communications.
NASA's Chandra X-ray Observatory 9 Jan 2019, 22:32 UTC A ricocheting jet blasting from a giant black hole has been captured by NASA's Chandra X-ray Observatory, as reported in our latest press release. In this composite image of Cygnus A, X-rays from Chandra (red, green, and blue that represent low, medium and high energy X-rays) are combined with an optical view from the Hubble Space Telescope of the galaxies and stars in the same field of view. Chandra's data reveal the presence of powerful jets of particles and electromagnetic energy that have shot out from the black hole. The jet on the left has slammed into a wall of hot gas, then ricocheted to punch a hole in a cloud of energetic particles, before it collides with another part of the gas wall.
