The Voyager I spacecraft went haywire last year, but NASA engineers say they have finally fixed its data transmission systems and are receiving usable signals from all four science instruments.

Snapped from lunar orbit in 1968 by NASA astronaut Bill Anders, who died this week at age 90, 'Earthrise' is perhaps the most iconic image of our planet ever taken.

The newly announced Landolt NASA Space Mission will launch a bread box-size "artificial star" satellite that will mimic stars by shining lasers directly at ground-based telescopes. This will enable astronomers to fine-tune instruments and potentially revolutionize how we study the universe.

Boeing's Starliner spacecraft successfully carried two NASA astronauts to space today (June 5) in the final test of the spacecraft's capabilities. Starliner is bound for the International Space Station.

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.
