NASA's Goddard Space Flight Center 3 Apr 2020, 12:11 UTC This remarkable spiral galaxy, known as NGC 4651, may look serene and peaceful as it swirls in the vast, silent emptiness of space, but don’t be fooled — it keeps a violent secret. It is believed that this galaxy consumed another smaller galaxy to become the large and beautiful spiral that we observe today.
NASA's Jet Propulsion Laboratory News and Features 1 Apr 2020, 16:31 UTC NASA's Wide Field Infrared Survey Telescope (WFIRST) will search for planets outside our solar system toward the center of our Milky Way galaxy, where most stars are. Studying the properties of exoplanet worlds will help us understand what planetary systems throughout the galaxy are like and how planets form and evolve.
SLAC National Accelerator Laboratory 31 Mar 2020, 19:43 UTC Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.

Kavli Institute for the Physics and Mathematics of the Universe 30 Mar 2020, 05:00 UTC An international team of researchers has found that neon inside a certain massive star can eat so many electrons in the core, a process called electron capture, which causes the star to collapse into a neutron star and produce a supernova.
NASA's Goddard Space Flight Center 27 Mar 2020, 11:30 UTC NGC 4618 was discovered on April 9, 1787, by the German-British astronomer William Herschel, who also discovered Uranus in 1781. Only a year before discovering NGC 4618, Herschel theorized that the “foggy” objects astronomers were seeing in the night sky were likely to be large star clusters located much farther away than the individual stars he could easily discern.
NASA's Jet Propulsion Laboratory News and Features 26 Mar 2020, 19:03 UTC NASA's "Send Your Name to Mars" campaign invited people around the world to submit their names to ride aboard the agency's next rover to the Red Planet. Some 10,932,295 people did just that. The names were stenciled by electron beam onto three fingernail-sized silicon chips, along with the essays of the 155 finalists in NASA's "Name the Rover" contest.The chips were then were attached to an aluminum plate on NASA's Perseverance Mars rover at Kennedy Space Center in Florida on March 16. Scheduled to launch this summer, Perseverance will land at Jezero Crater on Feb. 18, 2021.
NASA's Jet Propulsion Laboratory News and Features 25 Mar 2020, 19:03 UTC Eight and a half years into its grand tour of the solar system, NASA's Voyager 2spacecraft was ready for another encounter. It was Jan. 24, 1986, and soon it would meet the mysterious seventh planet, icy-cold Uranus.The dataset is still the only up-close measurements we have ever made of the planet. Three decades later, scientists reinspecting that data found one more secret.
NASA Glenn Research Center 24 Mar 2020, 18:00 UTC After four months of rigorous testing in the world’s premier space environments simulation facility at NASA’s Plum Brook Station, the Orion spacecraft for the Artemis I mission is certified and another step toward being ready for flight.
