New research shows that a planet spotted around the real-life star 40 Eridani A, famous for hosting Dr. Spock's fictional home world in 'Star Trek', may have been an optical illusion all along.

Vibrant auroras that were recently observed by millions of people across the globe were some of the most widespread in the last five centuries, NASA says. The light shows may have also reached the equator.

NASA's plan to build a train track on the moon is part of the agency's Innovative Advanced Concepts program, which aims to develop "science fiction-like" projects for future space exploration.

Just a few laps of the wall a day may be enough to keep muscle wasting at bay, scientists say.

The first crewed launch of Boeing's Starliner space capsule was canceled on Monday (May 6) due to a loudly buzzing valve on the Atlas V rocket carrying it. The delay is yet another headache for Boeing in its attempt to get its Starliner capsule up and running.

Newfound rocks on Mars suggest the planet may have once sported an oxygen-rich atmosphere, making it more Earth-like and hospitable to life than previously thought.

Mars has had frequent planet-wide auroras in recent months, including an unprecedented trio of events in February. Experts say the sudden increase is the result of the ongoing solar maximum.

NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.

A dog-like, bio-inspired robot called Spirit is still learning to walk, but could one day be deployed on the moon to explore steep, potentially hazardous areas with a team of robot companions.

A surprise coronal mass ejection recently smashed into Comet 12P/Pons-Brooks, briefly causing the "devil comet" to lose its tail — and a NASA spacecraft caught the whole thing on camera.
