An atmospheric haze around a faraway planet—like the one which probably shrouded and cooled the young Earth—could show that the world is potentially habitable, or even be a sign of life itself.
The long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars.
The planet Mercury is being pelted regularly by bits of dust from an ancient comet, a new study has concluded. This has a discernible effect in the planet's tenuous atmosphere and may lead to a new paradigm on how these airless ...
Ice volcanoes have shaped my life, and until today I didn't even know if they actually existed. Now, thanks to NASA's New Horizons spacecraft, there's a good chance we've found a frozen volcanic cone on the surface of Pluto.
A year ago on Thursday, the world held its collective breath as a European spacecraft dropped a tiny robot lab onto the surface of a comet hurtling towards the Sun.
Researchers propose an ammonia-water slurry as the basis for Pluto's newly discovered geologic activity and possible volcanism, and offer a new method to predict planetary vigor.
Buried in the shallow soft mud of a dry California lake bed, a seismometer was able to detect the tiny tilts of the ground as it was pulled up by passing dust devils. The experiment, described online November 10 in the Bulletin ...
Two University of Wisconsin-Stout professors are taking their students to Mars.
Europe's fifth and sixth Galileo satellites – subject to complex salvage manoeuvres following their launch last year into incorrect orbits – will help to perform an ambitious year-long test of Einstein's most famous theory.
NASA's New Horizons spacecraft has successfully performed the last in a series of four targeting maneuvers that set it on course for a January 2019 encounter with 2014 MU69. This ancient body in the Kuiper Belt is more than ...
