Thanks to ESA's Venus Express data, scientists obtained the first large-area temperature maps of the southern hemisphere of the inhospitable, lead-melting surface of Venus.

Subatomic particle appeared without its antimatter partner, says physicist Ann Heinson, co-leader of group of 50 scientists

The future of European astronomy is poised to enter a new era of discovery with the decision announced today by ESO's governing body to proceed with detailed studies for the European Extremely Large Telescope (E-ELT).

New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth's and Sun's magnetic fields connect, or merge, and not by the solar wind's electric field as was previously assumed. The merging occurs at a spot between the Earth and Sun, roughly 40,000 miles above the planet's surface, and appears fundamental to the circulation of particles and magnetic fields throughout near-Earth space.

How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated.

The Moon is in the center of attraction. Several space agencies are working to reveal known facts about the Moon to understand its evolution. As the Indian Space Research Organisation (ISRO) officials say it will help them to understand Earth as well. The last expedition on the Moon was 40 years ago, this means that new expeditions can give us much more thanks to its hi-tech equipment. The updated equipment will give a great chance to stay longer in the space. It will be about 180 days.

NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be reevaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also supports the presence of liquid water near the surface.

NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years.
