Water found 1 in. beneath Martian surface could help future astronauts

When the first astronauts land on Mars, they won't be able to take everything they need with them. The logistics and weight of transporting so much material on one spacecraft, along with a crew, defies current technology. While scientists at NASA have discussed missions to deliver materials to the Red Planet ahead of a manned mission, there may be resources on Mars that can be used.

Real-life planets you may have first seen in a 'Star Wars' film

A long time ago in a galaxy far, far away, there was a breathtaking diversity of planets. From the cockpit of the Millennium Falcon, rebel ships and Imperial cruisers, we've seen a colorful variety of them come into view. Harsh deserts baked by twin suns, craggy caverns, lush forests, water worlds, mineral-coated surfaces, inhospitable ice, inhabited moons and even lava worlds have greeted our gaze.

This is one place on Earth where no life can exist

Life exists in extreme environments on Earth, from arid deserts and frozen tundras to thermal, toxic vents in the deepest reaches of the ocean floor. But it can't exist on every inch of the planet and scientists have discovered a place in Ethiopia where life can't find a way, according to a new study.

Rover explores the solar system's oceans

Astronomers have uncovered increasing evidence that some bodies in our solar system, like Jupiter's moon Europa and Saturn's moon Enceladus, are actually ocean worlds.

Flat earth conspiracy spreads globally

"I don't want to be a flat Earther," David Weiss says, his voice weary as he reflects on his personal awakening. "Would you wake up in the morning and want everyone to think you're an idiot?"

The Mars 2020 rover lands February 2021

When the Mars 2020 rover lands on the Red Planet in February 2021, it will touch down in Jezero Crater, the site of a lake that existed 3.5 billion years ago. Now, two research teams have identified areas in Jezero Crater where the rover might find signs of ancient life.
