Satellite data shows that this year's ozone hole grew to around twice the size of Antarctica. Researchers say the eruption of Tonga's underwater volcano early last year may be partially to blame for the enormous cavity.

Astronomers may have detected a dozen large objects lurking beyond the Kuiper Belt at the edge of our solar system, suggesting there could be another equally massive, "second Kuiper Belt" hiding beyond the orbit of Pluto.

Atoms within the enormous ball of iron in Earth's inner core may move around much more than previously thought, which could explain recent findings about the core's surprising softness.

Hefty iceberg D-30A has collided with Clarence Island — an important refuge for breeding penguins in Antarctica. But luckily, the penguins weren't at home when the berg struck.

The Perseverance rover has captured footage of an unusually large twister, or "dust devil," moving across the Martian landscape. Based on images of the swirling storm, researchers estimate that it could be more than a mile tall.

The newly identified titanosaur, Garumbatitan morellensis, roamed what is now Spain around 122 million years ago. The unusual shape of some of its bones could hold clues about the evolutionary history of a unique group of sauropods.

On an expedition in Hawaii, a remote underwater vehicle filmed a dumbo octopus swimming with its ear-like fins near the seafloor. The pale white creature is one of the deepest-dwelling octopuses on Earth.

After surviving its closest approach to the sun, Comet Nishimura was buffeted by a possible coronal mass ejection that briefly blew its tail away. The rare event was captured by a NASA spacecraft.

NASA astronaut Frank Rubio has finally returned home from a 371-day stay on the International Space Station — a record for an American — after being trapped when his ride home was damaged.

Fossilized tree analysis finds a single massive earthquake may have rocked what is now Seattle around 1,100 years ago rather than several smaller quakes, and that another equally powerful one could hit the city in the future.

The James Webb Space Telescope has snapped a stunning image of a perfectly formed Einstein ring, which is also the most distant gravitationally lensed object ever detected.

NASA's James Webb Space Telescope has spotted a distant supernova that appears three times in the same photo. The new observations could help solve one of the universe's biggest inconsistencies.

A new study has found that the famous Australian lungfish Methuselah, who first arrived in the U.S. in 1938, could be up to 101 years old.

A rocket carrying a Space Force surveillance satellite may have created a hole in the ionosphere as it shot into space. The launch was carried out with just 27 hours' notice, which is a new record.

The seven-arm octopus, which actually has eight arms, is one of the largest octopus species and is rarely seen by people because it normally dwells in the deep sea.

Anglers in Texas reeled in a 283-pound alligator gar after a lengthy battle with the enormous fish. Experts say the catch likely breaks a 72-year record.

Comet Nishimura, which was only discovered in August, has survived its closest approach to the sun and will brighten over the next week. But is it still visible from Earth?

The James Webb Space Telescope captured a new image of a young sun-like protostar spitting out gas and dust that forms stunning shockwaves when viewed in infrared.

NASA's James Webb Space Telescope has detected potential traces of dimethyl sulfide, a chemical only known to be created by phytoplankton on Earth, in the atmosphere of an exoplanet believed to have its own liquid ocean.

Some scientists are pushing for species named after offensive people such as Hitler to be renamed, but the official governing body that guides species renaming is opposed.

Scientists have developed a nuclear fuel source no larger than a seed, which NASA will test for use in future moon missions.

The comet Nishimura, which was only discovered in August, will soon be slingshotted around the sun and back out toward the edge of the solar system where it will remain for centuries.

Researchers have shown that if the James Webb Space Telescope was pointed at Earth from a distant star, it could detect the signatures of intelligent life in our planet's atmosphere.

Researchers accidentally stumbled on a way to measure the size of the accretion disks of dust, gas and plasma that surround black holes.

Past research suggests that some whale species are more likely to get lost and accidentally beach themselves during periods of increased solar activity, such as the upcoming solar maximum.
