A new multiwavelength 3D visualization of the iconic "Pillars of Creation" showcases the differences between Hubble and James Webb Space Telescope data.

The X-ray-emitting binary system Cygnus X-3 features a massive star donating matter to a compact object, probably a black hole. That may explain its perplexing brightness.

The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many more are waiting to be discovered?

On Saturday (June 29), an asteroid larger than the Great Pyramid of Giza will fly past Earth at about three-quarters the distance from Earth to the moon. The asteroid, named 2024 MK, poses no risk to our planet.

Thousands of pieces of space debris, also known as space junk, are orbiting Earth, with tons more added each year. This orbital debris poses a significant threat to satellites, spacecraft, astronauts — and increasingly humans on Earth.

ISS astronauts, including the stranded Butch Willmore and Suni Williams, have sought refuge inside their docked spacecraft after the Resurs-P1 satellite splintered apart in orbit.

The International Space Station is nearing the end of its operational life. Now NASA is developing a plan for SpaceX to destroy it.

Astronomers using the James Webb Space Telescope (JWST) have spotted a previously unseen structure in the atmosphere above Jupiter's famous Great Red Spot.

Using the James Webb Space Telescope, astronomers have discovered an improbably huge black hole near the dawn of time, which doesn't seem to be eating near as much as it should.

A gargantuan "exhaust vent" may be channeling hot gas away from the Milky Way's supermassive black hole at millions of miles per hour — and filling up two enormous bubbles that tower over the galaxy.
