Max Planck Institute for Astronomy 3 Jan 2018, 03:03 UTC The motions of stars in a galaxy are like a history book, yielding information about how the galaxy has grown over time. Now a group of astronomers has assembled a library of such galaxy history books.
NASA's Ames Research Center News and Features 29 Dec 2017, 17:23 UTC NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, is preparing for its 2018 observing campaign, which will include observations of celestial magnetic fields, star-forming regions, comets, Saturn’s giant moon Titan and more.
NASA's Jet Propulsion Laboratory News and Features 22 Dec 2017, 16:15 UTC After several months of downtime after Hurricane Maria blew through, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its Dec. 16 flyby of Earth. The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal in shape and has a large concavity at least several hundred meters in extent near the leading edge, and a conspicuous dark, circular feature near one of the poles. Arecibo's radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel.
NASA's Goddard Space Flight Center 22 Dec 2017, 14:34 UTC The Hubble Space Telescope captured what looks like a colorful holiday ornament in space. It's actually an image of NGC 6326, a planetary nebula with glowing wisps of outpouring gas that are lit up by a central star nearing the end of its life.

NASA's Goddard Space Flight Center 22 Dec 2017, 12:41 UTC NASA is beginning to design its next big astrophysics mission, a space telescope that will provide the largest picture of the universe ever seen with the same depth and clarity as the Hubble Space Telescope.
NASA's Goddard Space Flight Center 21 Dec 2017, 18:00 UTC A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets.
ESA Top News 21 Dec 2017, 14:53 UTC With 2018 approaching rapidly and 2017 coming to a close, ESA can look back on a fruitful year. It has been a year dominated by the ESA astronaut missions to the International Space Station, the launch of more Sentinel satellites and the first launch of a small Geo satellite. This video looks back at the highlights of 2017 for ESA.
Harvard-Smithsonian Center for Astrophysics 20 Dec 2017, 19:12 UTC The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is the latest discovery to tantalize astronomers.
