ESA experts assess risk from exploded satellite
Paris (ESA) Mar 05, 2015
After studying the recent explosive break-up of a US satellite, ESA space debris experts have concluded this event does not increase the collision risk to nearby ESA missions in any meaningful way. The US Air Force's Defense Meteorological Satellite Programme Flight 13 (DMSP-13) broke up into some 40 pieces on 3 February. The military weather satellite was in a low-Earth orbit - commonly used by Earth observation missions and some communication satellites - at more than 800 km altitude. "The ... read more

Galactic 'rain' could be key to star formation Some of the galaxies in our universe are veritable star nurseries. For example, our own Milky Way produces, on average, at least one new star every year. Others went barren years ago, now producing ... more		Comet flyby: OSIRIS catches glimpse of Rosetta's shadow Images from the OSIRIS scientific imaging camera taken during the close flyby on 14 February have now been downlinked to Earth, revealing the surface of Comet 67P/C-G in unprecedented detail, and in ... more		Far from home: Wayward cluster is both tiny and distant Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place.
