Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA’s Mars Express on 4 January.

High-Resolution Stereo Camera nadir and colour channel data taken during orbit 11467 on 4 January 2013 by ESA’s Mars Express have been combined to produce this colour view of two craters, both roughly 50 …
Mars has lost much of its original atmosphere, but what’s left remains quite active, recent findings from NASA’s Mars rover Curiosity indicate. Rover team members reported diverse findings today at the European Geosciences Union 2013 General Assembly, in Vienna.

In the wake of the Space Shuttle’s demise, new spacecraft are being developed in droves. While all existing craft are space capsules, not unlike those used back in the Apollo era, several of the next generation of spacecraft may be spaceplanes. One contender is being built in Switzerland, with the first prototype to be completed next year.
The SOAR spaceplane … Read the rest of this article
The hundreds of volcanoes on Jupiter’s moon Io aren’t where they’re supposed to be, scientists say.
Io’s major volcanic activity is concentrated 30 to 60 degrees farther east than models of its internal heat profile predict, a recent study reports, suggesting that the exotic, volcanic Jupiter moon Io is even more mysterious than researchers had previously thought.
“The unexpected eastward … Read the rest of this article
A new paper led by a NASA researcher shows that hydrogen peroxide is abundant across much of the surface of Jupiter‘s moon Europa. The authors argue that if the peroxide on the surface of Europa mixes into the ocean below, it could be an important energy supply for simple forms of life, if life were to exist there. The … Read the rest of this article
NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon — a result of Einstein’s general theory of relativity — in binary, or double, star systems.

AAVSO Alert Notice 482Huan Meng and Dr. George Rieke (University of Arizona) have requested AAVSO assistance in monitoring three bright stars with developing planetary systems. The stars have been observed with NASA’s Spitzer Space Telescope to have varying levels of dust in the circumstellar disk. These … Read the rest of this article
NASA’s Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.

This is a Hubble Space Telescope view looking long ago and far away at a supernova that exploded over 10 billion years ago. The …
The antimatter hunter AMS-02 on the International Space Station is searching for the missing pieces of our Universe. The project’s first results published today are hinting at a new phenomenon and revealing more about the invisible ‘dark matter’.
AMS-02, the Alpha Magnetic Spectrometer, consists of seven instruments that monitor cosmic rays from space. Unprotected by Earth’s atmosphere the instruments receive … Read the rest of this article
Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object – either a brown dwarf or a giant planet – that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy.
