Astronomers using the James Webb Space Telescope have spotted a feeding black hole in the early universe that seems to be eating 40 times faster than is theoretically possible.

A shrieking skull, a cackling witch, a ghostly hand and other cosmic illusions haunt our skies. Which do you think is the spookiest object in the universe?

NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter, engineers are assessing the problem from 15 billion miles away.

The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.

From nebulas and black holes to baby star nurseries and ancient collisions, the universe has never looked more beautiful thanks to NASA's $10 billion-telescope.

A powerful solar outburst hit Earth Thursday, triggering a "severe" geomagnetic storm. Auroras could be visible as far south as California and Alabama, NOAA predicts.

On Oct. 2, a partial "ring of fire" solar eclipse was visible from the remote island of Rapa Nui, also known as Easter Island, where around 1,000 stone moai statues stand. You can see the whole celestial event play out in this incredible composite image.

The Oct. 2 partial solar eclipse, known as an annular or "ring of fire" eclipse, is about to begin over Easter Island and South America. Watch it for free right here.

On Sunday, Sept. 29, Earth captured a new "minimoon" called 2024 PT5. The bus-size asteroid is expected to orbit our planet for 57 days, but is too small to be visible to amateur skywatchers.

Vibrant auroras could be visible as far south as Oregon and Pennsylvania tonight as Earth reels from a "strong" G3-class geomagnetic storm. However, the nearly full Harvest Moon may complicate viewing opportunities.

The long-sought evidence of alien life could be lurking in Earth's oceans, says Harvard astrophysicist Avi Loeb. Here is his plan to find it.

Astronomers using the James Webb Space Telescope have discovered a pair of distant galaxies being twisted into a cosmic question mark thanks to a rare form of gravitational lensing.

Boeing's Starliner spacecraft will return to Earth today after undocking from the International Space Station without its crew. A livestream of the mission begins at 5:45 p.m. ET.

The U.S. Federal Aviation Administration (FAA) has grounded SpaceX's Falcon 9 rocket for the second time in as many months following a routine landing that ended in flames on Wednesday (Aug. 28).

NASA astronauts Butch Wilmore and Sunita Williams will spend at least eight consecutive months aboard the International Space Station as their Boeing Starliner spacecraft returns to Earth empty. Is their extended spaceflight record-setting?

Overnight on Aug. 20-21, the full 'Sturgeon Supermoon' briefly occulted, or passed in front of, Saturn, snuffing the ringed planet's light from the sky. An epic new astrophotography image captures the entire spectacle from start to finish.

Auroras may once again be visible in northern parts of the U.S. this weekend as Earth braces for impact from a powerful coronal mass ejection.

A UK-based astrophotographer captured this stunning composite image of the Perseid meteor shower raining "shooting stars" over Stonehenge.

Earth was hit by a "severe" G4-class geomagnetic storm on Monday morning, increasing the chances of auroras in the northern U.S. tonight.

NASA's asteroid-hunting NEOWISE space telescope will soon plunge into Earth's atmosphere and burn to bits. Here's a look back at its epic mission that defied all expectations.

A private company has received funding from the U.S. government to build the first-ever "streetlights" on the moon — towering, Statue of Liberty-sized structures that could withstand the brutal lunar night.
