Scientists are developing a novel space robot that can take up the challenge of hopping and rolling over microgravity terrain while doing valuable science.
After nearly 20 years gazing at the sun, the SOHO spacecraft is about to spy its 3,000th comet.
Tonight is the peak of the annual Perseid meteor shower and whether you have clear or cloudy skies, there are more than a few surprising ways that you can get involved and enjoy a potentially spectacular cosmic light show.
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.
The annual Perseid meteor shower will reach its peak this week, giving amateur skywatchers with clear dark skies a potentially dazzling celestial light show.
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.
Not only has NASA’s New Horizons mission confirmed that Pluto has an extended atmosphere, after its historic flyby on July 14, the spacecraft observed a “cavity” in the solar wind, revealing a long plasma tail reminiscent of a comet’s ion tail.
