A hyperactive sunspot recently unleashed its third X-class flare in under 24 hours. The X6 flare is the most powerful since 2017 and could be followed by equally massive explosions.

Researchers recently discovered an "incredible number" of potential new marine species, as well as a handful of hefty new seamounts while exploring the deep sea off the coast of Chile.

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.

A temporary lake at Badwater Basin in Death Valley National Park has persisted for more than six months, which is far longer than it has lasted before. And experts say that it could stick around for quite a while yet.

A new study shows that invasive Joro spiders are surprisingly "urban tolerant," which could enable them to take over cities and other urban areas across the U.S. East Coast.

The highly desiccated remains of a suspected bottlenose dolphin were recently found on a beach in South Carolina after "mummifying" for weeks or even months. One expert believes the animal may have deliberately beached itself.

The Hubble Space Telescope has snapped a stunning photo of one of the most distant Einstein rings ever found. The luminous halo of light aligns perfectly with another galaxy, making it look like a cosmic engagement ring.

Researchers found and mapped four seamounts in the deep sea off the coast of Peru and Chile. The tallest of these new peaks rises around 1.5 miles above the seafloor.

The underground volcano near Grindavík has begun its third major eruption in three months, opening up a 2-mile-long fissure that is pumping out large amounts of lava and ash.

The number of unprovoked shark attacks spiked slightly last year, while the number of fatal bites doubled compared with the previous year. However, the statistics are not as concerning as they initially sound, experts say.

Oleg Kononeko has broken the record for most cumulative time spent in space after spending his 878th non-continuous day onboard the International Space Station. But he won't return to Earth until September.

Newly sequenced genomes of blue whales in the Atlantic Ocean contain "unexpectedly high" levels of fin whale DNA, hinting that the two species have been interbreeding much more than previously realized.

As humans start to spread out among the solar system, new accents may begin to emerge in isolated colonies. But why does this happen and what will these new accents sound like?

A photographer recently snapped an incredibly detailed photo of gigantic, ghostly plasma loops towering above the sun's fiery surface after a powerful solar flare exploded from the sun.

A "potentially hazardous" space rock the size of a football stadium is about to reach its closest point to our planet for more than 100 years, and it won't get this close to us again for centuries more.

Researchers in Kenya successfully transplanted a white rhino embryo into a female surrogate for the first time. The pregnant mother-to-be died from an unrelated illness before she could give birth, but the procedure showed that some of the world's rarest animals can still be saved.

Ethereal green "aurora curls" were photographed in the night sky over Iceland after a gust of solar wind vibrated Earth's magnetic shield like a plucked guitar string. The phenomenon is extremely rare.

Later this year, the European Space Agency's Proba-3 mission will send two spacecraft into orbit around Earth. By aligning the probes, researchers will create 6-hour-long mini eclipses, allowing the sun's atmosphere to be studied like never before.

A brief flash of green light was recently spotted coming from Venus in the night sky. The colorful shimmer has only been seen a handful of times before.

A new deep-sea mapping project has revealed near-continuous reefs of cold-water corals spanning an area the size of Vermont just off the southeast U.S. coastline.

A pair of linked solar flares recently exploded near-simultaneously from sunspots on different hemispheres of our home star, triggering radio blackouts on Earth.

NASA's Lunar Reconnaissance Orbiter successfully bounced a laser off of a cookie-sized mirror on Inida's Vikram moon lander in an experiment that could greatly improve the precision of future moon landings.

New images from the James Webb Space Telescope have revealed a bizarre string of dust in the shape of a cat's tail around the nearby juvenile star Beta Pictoris.

The inexplicable entity, which likely had a chemical composition unlike any other known star, was identified by a group of "stellar archaeologists" who traced back the cosmic history of another equally unique star.

The green-tinged cryovolcanic Comet 12P/Pons-Brooks, which is due to pass by Earth later this year, was recently spotted zooming past the crimson-colored Crescent Nebula in stunning new photos.
