NASA's Goddard Space Flight Center 19 Dec 2019, 17:00 UTC NASA’s Fermi Gamma-ray Space Telescope has discovered a faint but sprawling glow of high-energy light around a nearby pulsar. If visible to the human eye, this gamma-ray “halo” would appear about 40 times bigger in the sky than a full Moon. This structure may provide the solution to a long-standing mystery about the amount of antimatter in our neighborhood.

Science Results - The 'Cores' of Massive Galaxies Had Already Formed 1.5 Billion Years after the Big Bang19 Dec 2019, 01:00 UTC A distant galaxy more massive than our Milky Way -- with more than a trillion stars -- has revealed that the 'cores' of massive galaxies in the Universe had formed already 1.5 billion years after the Big Bang, about 1 billion years earlier than previous measurements revealed. Researchers published their analysis on November 6, 2019 in The Astrophysical Journal Letters, a journal of the American Astronomical Society.
ESA Human Spaceflight and Exploration 18 Dec 2019, 15:31 UTC Someone decked the skies with boughs of sprites. The red jellyfish in the sky is a unique red sprite high above a storm across the southern plains of the United States. Taken in the early hours of 21 October by outdoor photographer Paul Smith, red sprites, along with blue jets and elves, are elusive electrical discharges in the upper atmosphere that are difficult to study as they occur over thunderstorms and propagate out into space.
NASA's Jet Propulsion Laboratory News and Features 18 Dec 2019, 15:28 UTC Astronaut Christina Koch recently gave a warm welcome to a very cool arrival to the International Space Station: a new piece of hardware for the Cold Atom Lab, an experimental physics facility that chills atoms to almost absolute zero, or minus 459 degrees Fahrenheit (minus 273 degrees Celsius). That's colder than any known place in the universe.
ESA Space Science 18 Dec 2019, 15:22 UTC ESA’s Characterising Exoplanet Satellite, Cheops, lifts off from Europe’s Spaceport in Kourou, French Guiana. The Soyuz-Fregat launcher will also deliver the Italian space agency’s Cosmo-SkyMed Second Generation satellite, and three CubeSats – including ESA’s OPS-SAT – into space today. Cheops is ESA’s first mission dedicated to the study of extrasolar planets, or exoplanets. It will observe bright stars that are already known to host planets, measuring minuscule brightness changes due to the planet’s transit across the star’s disc.
ESO Supernova 18 Dec 2019, 15:19 UTC On the occasion of the International Day of Women and Girls in Science, The Max Planck Institute for Extraterrestrial Physics (MPE) is organising its annual free event "Women in Astronomy" on 11 February 2020 at 19:00 at the ESO Supernova Planetarium & Visitor Centre. This year, the event will feature a presentation from Prof. Dr. Ing. Eva Grebel, Director of the Astronomical Computing Institute, Centre for Astronomy, University of Heidelberg on the topic of Galactic Archeology. The public talk will be delivered in the German language only. Before and after the lecture, the astronomy exhibition at the ESO Supernova will also be open to visitors, offering you the opportunity to talk to female scientists who are researching various topics in the field of astronomy.
NASA Glenn Research Center 18 Dec 2019, 14:54 UTC On December 18, 2001, NASA engineers shut down Deep Space 1, bringing to an end the first U.S. space mission utilizing ion thrusters as its primary mode of propulsion. Researchers at Lewis Research Center (now NASA Glenn) made significant contributions to the solar-powered xenon-gas-based electric propulsion system, referred to as the NASA Solar Electric Power Technology Application Readiness (NSTAR). The engine’s roots go back to the original electron bombardment thruster that Lewis researcher Harold Kaufman invented in the late 1950s.
