Rosetta is revealing its host comet as having a remarkable array of surface features and with many processes contributing to its activity, painting a complex picture of its evolution.
Mars has been the focus of a flurry of findings lately. The Curiosity rover has been exploring the Gale Crater, where it detected methane jets and also sampled clays from the dry lakebed there, discovering clues about the history of water and hydrogen on the planet. That points to Mars’ water, and hydrogen in its atmosphere, slowly being lost over a longer period than previously thought. Meanwhile, the MAVEN spacecraft, orbiting Mars, has observed the process that causes that loss.
Between the rovers and the MAVEN spacecraft, it’s no surprise that so many new findings have come to light. But amidst these discoveries, researchers have made yet another stride in understanding the planet’s history—and they’ve done so in a laboratory right here on Earth.
The meteorite, known as Allan Hills 84001, is named for the location in Antarctica where it was discovered in the 1980s. It originated on Mars and, crucially for the enterprise of studying the planet’s history, it’s about 3.9 billion years old. That puts its formation in the planet's water-rich Noachian era, so the carbonates it contains provide clues about this key period in the planet's history.

Blasting skyward an Atlas V rocket carrying a U.S. Navy satellite pierces a cloud bank in this starry night scene captured on January 20. On its way to orbit from Space Launch Complex 41, Cape Canaveral Air Force Station, planet Earth, the rocket streaks past brightest star Sirius, as seen from a dark beach at Canaveral National Seashore. Above the alpha star of Canis Major, Orion the Hunter strikes a pose familiar to northern winter skygazers. Above Orion is the V-shaped Hyades star cluster, head of Taurus the Bull, and farther still above Taurus it's easy to spot the compact Pleiades star cluster. Of course near the top of the frame you'll find the greenish coma and long tail of Comet Lovejoy, astronomical darling of these January nights.

These new images from the high-resolution stereo camera on ESA’s Mars Express show Nili Fossae, one of the most enticing regions on Mars. This ‘graben system’ lies northeast of the volcanic region of Syrtis Major on the northwestern edge of the large Isidis impact basin – and intriguing hints of methane have been seen here.
