Scientists now have a better understanding about a site with the most chemically diverse mineral veins NASA's Curiosity rover has examined on Mars, thanks in part to a valuable new resource scientists used in analyzing data ...
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.
Astronomers have discovered a mysterious dwarf planet that is three times farther away than Pluto and believed to be the most distant object in our solar system.
A new machine-learning simulation system developed at the University of Illinois promises cosmologists an expanded suite of galaxy models - a necessary first step to developing more accurate and relevant insights into the ...
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 ...
Since the late 1980s, scientists have discovered nearly 5,000 planetary bodies orbiting stars other than the sun. But astronomers are still working on what exactly we should call them.
Astronomers have identified for the first time one of the key components of many stars, a study suggests.
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.
