They also must authorize major programs, like the Artemis program, which aims to return the U.S. and its partners to the moon.

Let's set the record straight: NASA has not found a parallel universe. The claims making the rounds on social media are not based on new scientific findings but are instead a distorted interpretation of older research.

NASA is about to make history. Its Parker Solar Probe is set to fly closer to the sun than any object in history. The mission is years in the making.

With humans slated to return to the moon this decade, NASA has been testing new lunar vehicles in simulated low gravity.

What knocked this black hole over onto its side? It's a cosmic "whodunnit" that NASA scientists using the Hubble and Chandra space telescopes are trying to solve.

NASA's Parker Solar Probe is out of contact with mission control after its closest-ever pass of the sun on Tuesday, Dec. 24.

Early on Christmas Eve in 2024, a NASA craft swooped at blazing speed through the sun's atmosphere.

NASA’s Parker Solar Probe made its closest approach to the sun early Tuesday, getting within just 4% of the Earth-sun distance — a feat compared to the '69 moon landing.

Years of data analysis and new imaging techniques revealed an unusual phenomenon in NGC 5084: a supermassive black hole with four plasma plumes forming an "X" shape, rotating at a 90-degree angle.

Enjoy your holiday traditions, however niche they may be. You don’t have to go for a walk, unless you really want to. If today is just another work day, take a few minutes to find calm. And if all you fancy is takeout and the pleasure of your own company, we toast to that, too.

Space station crews spend the holidays away from family and friends, but that doesn’t stop them from celebrating in space.
