A new study using data from NASA's Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class of objects that are used to measure the rate of expansion of the Universe.
Electrically charged lunar dust near shadowed craters can get lofted above the surface and jump over the shadowed region, bouncing back and forth between sunlit areas on opposite sides, according to new calculations by NASA scientists.
A massive backplane that will hold the primary mirror of NASA's James Webb Space Telescope nearly motionless while it peers into space is another step closer to completion with the recent assembly of the support structure's wings.
The six science instruments that comprise the Particles and Fields Package that will characterize the solar wind and ionosphere of Mars have been integrated aboard NASA's Mars Atmosphere and Volatile EvolutioN spacecraft. The spacecraft is on track for launch later this year.
ESA is offering software developers the opportunity to use its new testbed in space. The robust nanosat will allow individuals, companies and institutions to try out pioneering software without the danger of losing a mission.
Europe's new age of satellite navigation has passed a historic milestone - the very first determination of a ground location using the four Galileo satellites currently in orbit together with their ground facilities.
