NASA has just turned off an especially helpful and loyal satellite that had finally reached the end of its life. Rest in peace, EO-1.

A sun-like star in the Large Magellanic Cloud, about 160,000 light-years away, showed signs of association with a Type Ia supernova.

NASA reveals plan to build a Deep Space Gateway near the lunar surface to serve as a pit stop for astronauts going to Mars.

Plans for the next International Space Station are in the works, and it looks like it's going to orbit the moon.

NASA Expedition 50 members, Shane Kimbrough and Peggy Whitson, are doing a spacewalk Thursday morning on the International Space Station.

The spacecraft began studying Mars from an orbital perspective in 2006, and images taken from its Context Camera now cover over 99 percent of the red planet.

Based on what compounds are on Uranus scientists have gathered that the planet probably smells bad.

NASA's Image and Video Library is full of thousands of stunning images of space.

A large disk galaxy and a small “dwarf” galaxy merged in a system called Was 49, and the smaller partner has been found with a much larger-than-expected supermassive black hole.

Lunar swirls are streaks of color on the Moon and are a feature that is unique to Earth’s only natural satellite.

In the winds rushing away from a supermassive black hole are all the right ingredients for new stars to be born.

Thanks to this spacewalk, you’ll soon be able to pile into a taxi and take it straight to the International Space Station.

The object, named Swift J0042.6+4112, was first detected in 2013 by NASA's Swift satellite.

Weighing more than 1 billion suns and about 8 billion light-years away, the black hole was likely kicked out of its place by gravitational waves with energy equivalent to 100 million supernovas exploding simultaneously.

NASA's climate change time machine shows how sea ice, CO2, temperature and sea level rise have changed over time due to climate change.

The space agency is working on a laser communications system that will allow for much faster connection speeds between spacecraft and ground stations.

Low levels of sea ice in the Arctic break another record, according to NASA.

A team proposed changing the official definition of a planet so that it would include Pluto...and 100 other celestial bodies.

The new NASA laser communication system is expected to begin in 2019.

President Trump signed the NASA Authorization Act on Tuesday, but SpaceX founder Elon Musk doesn't believe the bill will do much for the future of space exploration, including trips to Mars.

There’s a lot of garbage flying around the Earth, and that space debris is traveling 10 times faster than a bullet.
