This colossal dinosaur's fossils were so heavy, they broke the road during transport.

The time has come to expand our visions of life beyond Earth.

As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might explain why a large portion of exoplanets have water on their su…

The freshwater flatworm Stenostomum brevipharyngium is, by all accounts, a simple fellow. The worm is small and entirely soft. It has no eyes, only sensory pits that control balance and orientation. This simplicity makes it easy for S. brevipharyngium to make…

Some people were treated to an astral spectacle late Wednesday night, as a "fireball meteor" flashed across the night sky in parts of Minnesota and Wisconsin.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

Physicists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a striking new form of quantum behavior. In star-shaped Kagome crystals—named after a traditional Japanese bamboo-basket woven pattern—electrons …

Earth's mantle is so gooey, it takes eons for material that has been displaced by the weight of ice sheets to flow back. And Greenland is very much still processing its glacial past, a new study shows.

"Twelve-year paramedic here. In the US, at least, pull to the right when an emergency vehicle is coming. Do not pull left or stop in the middle of the road. PULL TO THE RIGHT."

The discovery of non-cyanobacteria diazotrophs underneath Arctic sea ice could change our understanding of the food web, as well as the ocean's carbon budget...

The International Space Station is marking 25 years of nonstop human presence in orbit. Nearly 300 people have lived aboard the scientific outpost. The visitors are mostly professional astronauts, but also the occasional space tourist and movie director. With…

New study uses logic and physics to definitively answer one of science's biggest questions

James Webb Space Telescope spots the haunting Red Spider Nebula with 3-light-year-long legs

The African continent is gradually splitting apart. Although a new ocean is expected to form as a result, it won't be for millions of years.

Scientists have made some intriguing parasite discoveries in an accidental back-of-the-pantry natural history museum. Canned salmon, well past its prime, has preserved decades of Alaskan marine ecology in brine and tin.

Astronomer Avi Loeb suggests that a quasi-satellite may be the "relic of an interplanetary mission by humanity from the 1960s."

This week, astronomers in China have detected a series of unusual radio signals from comet 12P/Pons-Brooks.

Scientists have long sought to make semiconductors—vital components in computer chips and solar cells—that are also superconducting, thereby enhancing their speed and energy efficiency and enabling new quantum technologies. However, achieving superconductivit…

Every year, the Taurid meteor shower lights up the night sky from late October through early November. Sometimes called the "Halloween fireballs," they are named for the constellation Taurus—the bull—from which the meteors appear to radiate. The shower is bes…

Sydney scientists fixed NASA’s James Webb Space Telescope without ever leaving Earth. Using AI-powered software called AMIGO, they eliminated image blurring caused by subtle electronic distortions. The fix restored the telescope’s full power to reveal distant…

The Milky Way is a rich and complex environment.

After initial enthusiasm from its deep-space tracking network, China’s astronomical silence on 3I/ATLAS after the object’s Mars encounter has raised questions, was it a technical limit, a policy shift, or deliberate restraint?

A fossil braincase and partial skull roof from Carnegie Museum of Natural History has been reassessed and reclassified, giving rise to a new genus and species of dicraeosaurid sauropod dinosaur: Athenar bermani.
