Engineers have bought the spacecraft's interstellar mission more time by using backup power from a safety mechanism. It means NASA no longer has to shut down one of its five scientific instruments.

New efforts are aimed at training journalists to better support sources and care for their own mental health while reporting.

The space agency will send four astronauts towards the moon for the first time in more than 50 years.

Data from an old NASA spacecraft reveals a volcano erupted on the surface of Venus in 1991, a new study in Science says.

Scientists are pondering how to tell time on other celestial bodies. It's a lot harder than you might think.

NASA's Double Asteroid Redirection Test slammed a spacecraft into an asteroid, directly altering its path through space. Scientists are still studying the space rock to learn more.

NASA's Mars Reconnaissance Orbiter snapped the uncanny photo in December. Eyes are formed by craters. A hill with a "V-shaped collapse structure" resembles a snout.

There was no reason for alarm, as a NASA engineer called it "one of the closest approaches by a known near-Earth object ever recorded." It was only 2,200 miles above the Earth's surface.

The exoplanet was found using a satellite and spectrography. It has a similar size as Earth, but is much hotter and completes its orbit around its star in two days.

NASA successfully crashed a spacecraft into an asteroid in a test of planetary defense. Now it will determine whether the mission was able to alter the asteroid's course.
