The exoplanet is five billion years old, and takes 14 days to orbit its star. Scientists observed starquakes to determine its properties.
NASA’s Curiosity rover has been exploring Mars for 6 years now — here’s what the red planet’s surface looks like up close
NASA's Curiosity rover has been at Mars for six years now. Some photos of the Martian surface look like the prototypical idea of the red planet: rocky, dry, and dusty. Yet other craters and canyons offer otherworldly colors and patterns.
If we don't do anything to cut emissions and limit climate change, the worst case scenario involves severe heat waves, acidic oceans, and superstorms.
Earth entered a new epoch on July 16, 1945 — and that’s just the beginning of how humans have changed the planet
While nature is responsible for more than 5,000 of Earth's minerals, people are responsible for more than 200. That impact will be noticeable for many years.
Even if Earth spends the rest of its eons escaping aliens, dodging space rocks, and avoiding nuclear apocalypse, the day when our own sun destroys us will come.
Ceres might not be a planet. And it might not be king of the asteroids. But it’s home to a giant volcano made of ice. And that’s pretty cool.
Scientists may have just found an Earth-like planet orbiting our sun’s nearest neighbor — and it’s our best chance of finding alien ...
On Wednesday, an international team of scientists announced that the closest star to our solar system might be our best bet at finding alien life.
There’s a mysterious object doing a crazy loop around our solar system, but scientists have no idea what it is
Scientists have nicknamed it "Niku," which means "rebellious" in Chinese. And the object's reckless behavior has scientists scratching their heads.
The surface of Mars is woven with beautiful gullies. Until recently, scientists thought that liquid water played a role in carving out these vein-like channels.
“Somehow Ceres has healed its largest impact scars and renewed old, cratered surfaces,” said Simone Marchi, lead author of the study, in a NASA press release.
