On Aug. 13, Comet 67P/Churyumov-Gerasimenko will reach perihelion, and with it the orbiting European Rosetta mission. Here's a brief rundown of Rosetta's observations of the icy body in the run-up to its day in the sun.
On July 29, with ESA's Rosetta spacecraft in orbital tow, the 2.5-mile-long Comet 67P/Churyumov-Gerasimenko fired its brightest jet yet since Rosetta's arrival just over a full year ago.
As Comet 67P/Churyumov-Gerasimenko approaches perihelion, the sun is heating up its nucleus and the solar wind is causing its tail to evolve. And the Rosetta mission has a ringside seat.
Astronomers proposed a novel explanation for the strange appearance of the comet carrying Europe's robot probe: microscopic aliens.
Scientists have found gigantic sinkholes more than 200 yards (183 meters) in diameter -- twice the length of a football field -- and just about as deep breaking the surface of the comet being studied by the orbiting Rosetta spacecraft.
Ground control teams overseeing Europe’s Philae comet lander begin the week with some good news: The intrepid robot is back talking to the orbiting Rosetta spacecraft.
After a 7-month hiatus, the revived European comet lander is nearly ready to resume work, expanding on our scientific understanding of the solar system.
Wake up, Philae! Here are five more spacecraft rescued after their missions could have terminated.
