Scientists and engineers in California are building a unique 3.2 billion pixel camera for a telescope under construction in Chile. The camera has taken its first test pictures — of broccoli.
An experiment involving some "mighty mice" on the International Space Station could someday help astronauts maintain muscle and bone strength on interplanetary journeys.
None of us is perfect, and sometimes the Hubble Space Telescope just flat-out points to the wrong spot in the sky. This has been happening more than ever in the last couple of years.
An experimental drug let mice spend a month in the International Space Station's near-zero gravity without losing mass. It could help people spend years in space without major health consequences.
Scientists have long debated whether the Earth's water was here when the planet formed or whether it arrived later. A study suggests much of the water originated in rocks from which Earth is built.
The cable tore a gaping 100-foot hole in one of the largest radio telescope dishes in the world, taking the instrument offline until repairs can be made.
The light of the moon will reduce the visibility of some fainter meteors, but NASA says it's still worth staying up late — or rising very very early on Wednesday — to see "nature's fireworks."
Satellite images were once restricted to governments. Now anyone can get them, creating a new world of possibilities for environmentalists, human rights groups and those monitoring nuclear weapons.
NASA and SpaceX are welcoming home two astronauts who splashed down safely in the Gulf of Mexico after several months on the International Space Station.
Dr. Deborah Birx says COVID-19 has entered a new phase. Presumptive Democratic nominee Joe Biden is close to naming a running mate. What the successful SpaceX landing means for space exploration.
The two NASA astronauts who flew on the SpaceX craft to the International Space Station in May are scheduled to return to Earth on Sunday. But there's a hurricane forecast for the splashdown vicinity.
A Russian satellite hatched from another satellite fired a projectile last week that American military officials say is meant to take out other satellites. Moscow says it's an inspection tool.
Tianwen-1, which combines an orbiter, lander and rover in a single shot, would be China's second attempt to reach the red planet after a 2011 mission failed.
