The agency is considering how to conduct science experiments on the Deep Space Gateway station, even while no crew members are on board.

Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof that you were right.

For the last few years, NASA has promoted solar electric propulsion (SEP) as a key aspect of its long-term plans to send humans to Mars. NASA's Asteroid Redirect Mission (ARM) was going to demonstrate one such advanced S...

The upper atmosphere of the giant exoplanet WASP-121b may be wreathed in layers of glowing water vapor --

According to one longstanding theory, our Solar System's formation was triggered by a shock wave from an exploding supernova. The shock wave injected material from the exploding star into a neighboring cloud of dust and ...
