Young stars can hide, but Hubble's good at seeking them out. The famed space telescope spotted the "smoking gun" of a newborn star about 1,000 light-years away from Earth.

While residents of the northern half of the Earth prepare for shorter days and colder weather — the first day of fall is Friday (Sept. 22) — there is a sky spectacle to enjoy.

Solar power took a dip in the United States when the total eclipse swept across the country Monday (Aug. 21), as a new video shows.

The coast-to-coast total solar eclipse on Aug. 21 will be memorable for children and adults alike, and a new website will help kids get interested in the big event and view it safely.

Scientists aren't sure if a big dimple on Mars came from something smacking into the Red Planet's surface or if it was simply caused by a collapse.

A star's mysterious evolution recently came to light using the Hubble Space Telescope, which spotted the star cooling after a rapid temperature increase in the past.

While engineers are still struggling with seemingly impossible physics for warp drives and transporters, NASA is using some technology in space that would be at home on the starship Enterprise.

NASA has finally re-established contact with a sun-watching probe that was once thought lost in space after it abruptly went silent in 2014.

Robots are already in space and benefiting humans, NASA says, even though (so far) we don't have trusty R2-D2s by our side bleeping comments and questions.

A star is dimming for reasons that astronomers can't explain. Is it an alien megastructure? What sort of alien megastructures would be possible?

The annual Perseid meteor shower will reach its peak this week on Wednesday (Aug. 12) and Thursday (Aug. 13), giving amateur skywatchers an evening show.

The technology powering robotic arms in space could be used to perform minor surgeries for children on Earth.
