ESA is announcing an opportunity for scientists involved in Earth observation to submit proposals for the next potential Earth Explorer satellite mission.
Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.
Ice volcanoes, twirling moons: Four months after Pluto flyby, New Horizons yields wealth of discovery
From possible ice volcanoes to twirling moons, NASA's New Horizons science team is discussing more than 50 exciting discoveries about Pluto at this week's 47th Annual Meeting of the American Astronomical Society's Division ...
Astronomers have used modern techniques to visualise data from ESA's Hipparcos space astrometry mission in three dimensions. The treatment of the data has offered insights into the distribution of nearby stars and uncovered ...
What happens to your body in space? NASA's Human Research Program has been unfolding answers for over a decade. Space is a dangerous, unfriendly place. Isolated from family and friends, exposed to radiation that could increase ...
Since it began operations in December 2009, NASA's NEOWISE mission has observed 158,000 asteroids and discovered more than 35,000.
Researchers propose an ammonia-water slurry as the basis for Pluto's newly discovered geologic activity and possible volcanism, and offer a new method to predict planetary vigor.
Spacewalking astronauts encountered leaking ammonia and minor glove damage while performing plumbing work outside the International Space Station on Friday, then fell so far behind that they had to leave a radiator job undone.
OSIRIS, the scientific imaging system of ESA's Rosetta mission to comet 67P/Churyumov-Gerasimenko, shows a surface with subtle, but significant color variations.
The Cassini spacecraft took a daring plunge into the icy geysers of Saturn's moon Enceladus this week in search of telltale signs of a habitable environment.
