NASA probe aims to unlock Mercury's secrets (Update)
NASA scientists pored Wednesday over stunning new images of Mercury as their MESSENGER probe began a year-long mission to map the surface of the solar system's least-understood planet.
NASA spacecraft trying to get into Mercury's orbit
A desk-sized NASA spacecraft is riding the brakes all the way to Mercury, about to pull a tricky maneuver Thursday night to become the first man-made object to orbit the tiny planet.
Satellite measures gravity's effect on climate change
After nearly two years in space, the European satellite GOCE has collected the raw data needed to map variations in Earth's gravity field, the European Space Agency has said.
Japan's first Venus probe struggling to enter orbit
Japan's first space probe bound for Venus was struggling on Tuesday to enter the planet's orbit, the space agency said.
Japan probe reaches Venus but shuts itself down (Update)
(AP) -- A Japanese space probe sent to the thick clouds of Venus shut itself down, and its future looks as hazy as the planet it was built to study.

Extreme X-ray source supports new class of black hole
A group of international astronomers in the UK, France and the USA, led by the University of Leicester, have found proof to confirm the distance and brightness of the most extreme ultra-luminous X-ray source, ...
Climate: New study slashes estimate of icecap loss
Estimates of the rate of ice loss from Greenland and West Antarctica, one of the most worrying questions in the global warming debate, should be halved, according to Dutch and US scientists.

European science satellite hit by glitch
A satellite designed to map Earth's gravitational field has been hit by a software glitch and is unable to send its science data back home, the European Space Agency (ESA) said on Monday.
Quantum gas in free fall: Physicists produce a Bose-Einstein condensate at zero gravity
(PhysOrg.com) -- A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument. A team of researchers including scientists from the Max Planck Institute of ...
