Supermassive black holes represent one of the biggest head-scratchers in the Universe.

NASA's Transiting Exoplanet Survey Satellite (TESS) detected three rocky planets around the M-dwarf L 98-59 in 2019. While two are expected to be hot, rocky worlds, the third could be covered by a global ocean. A fourth planet was discovered in 2021, and now,…

He was totally fine.

In May, the US administration proposed budget cuts to NASA, including a more than 50% decrease in funding for the agency’s Earth Science Division

Tentative detections of life-linked molecules in a star’s disk suggest planets may form with the ingredients for life already in place.

Thanks to auroras and other space weather, humans have adapted techniques to overcome these issues.

Senegal signed the Artemis Accords Thursday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the latest nation to commit

Collapsing stars might act as cosmic laboratories for discovering hidden neutrino interactions. Neutrinos are among the most puzzling particles in the universe. Nearly massless and incredibly elusive, they rarely interact with anything, yet they play a deadly…

While all the technology of the Apollo program still exists in the form of blueprints and designs, all the human expertise that went into crafting those rockets and spaceships is now either retired or passed away.

"Spain wants and can be the home of the future of astronomy and astrophysics."

A long-misidentified fossil, once thought to be a caterpillar, has revealed itself as a groundbreaking discovery in early animal evolution.

Or is it actually a great idea.

In a surprising twist, two of Arizona’s most iconic landmarks—Meteor Crater and the Grand Canyon—may be linked by a cosmic event that occurred around 56,000

In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature.

The discovery of the Higgs boson hasn’t led to a explosion of new physics. Now, some scientists think that hidden physics may be hiding beyond LHC’s view.

Astronomers have used a novel technique to find evidence of a secret "buddy" star orbiting Betelgeuse, one of the brightest objects in the night sky — but this sun-size companion may not survive for long.

The universe can be beautiful, as Chandra and other observatories reveal.

Watch as part of the Earth slides away from the other in a dramatic shake-up.

When you've just been drowned by an alien robot, you don't tend to be all that hungry.

With a giant beak, the terror bird would have proved a formidable foe for most. Paleontologists think it may have been killed by a crocodile-like creature.

A technology called Dynamic Targeting could enable spacecraft to decide, autonomously and within seconds, where to best make science observations from orbit.

The theorists predict that the beginning of the end will be in about 10 billion years — less than the present age of the universe.
