An astronomer and a group of eagle-eyed citizen scientists have discovered a giant gas planet hidden from view by typical stargazing tools.

Astronomers have discovered at least 70 new free-floating planets — planets that wander through space without a parent star.

Aerospace engineers at MIT are testing a new concept for a hovering rover that levitates by harnessing the moon’s natural charge.

Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information.

NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there.

The new office will focus on incidents in, or near, "special use airspace" areas strictly controlled and blocked from general aviation use.

When Earth formed 4.5 billion years ago, any phosphorus that was present likely sank into the molten core due to the element's properties.
