Liftoff is scheduled for 3:49 a.m. ET on Monday (Dec. 15).

NASA is sending a robotic arm into orbit to help construct habitats and vital infrastructure in space, and Space X is lending a hand. It’s been more than five decades since American astronauts have been on the Moon. But earlier this year, NASA announced plans…

Liquids and solutions are complex environments—think, for example, of sugar dissolving in water, where each sugar molecule becomes surrounded by a restless crowd of water molecules. Inside living cells, the picture is even more complex: tiny liquid droplets c…

In a new study published in Nature Physics, researchers have achieved the first experimental observation of a fragile-to-strong transition in deeply supercooled water, resolving a scientific puzzle that has persisted for nearly three decades.

Ancient tools, 3 million years old, have been discovered in Kenya, reshaping our understanding of early human technology.

Researchers believe that a new epoch may have begun on the Moon back in 1959, when humans first affected the surface.

Incredible dinosaur fossil reveals secrets of how it sounded, and what was inside its stomach!

December's faint Ursid meteor shower returns under dark skies, offering a small chance of unexpected activity.

Curiosity rover has uncovered something unexpected on Mars, hinting at a surprising twist in the planet's ancient history. What it found could change everything we thought we knew.

Scientists have uncovered shocking evidence that Earth’s largest ocean might be buried deep beneath our feet—hidden for billions of years inside solid rock. This discovery is rewriting everything we thought we knew about where our planet’s water came from… an…

The spider-like formation could be evidence of epic eruptions of water that blast through Europa' surface.

Researchers have figured out why V Sagittae is so gosh dang bright.

Taikonauts Zhang Lu and Wu Fei installed debris protection panels on China's Tiangong during an eight-hour spacewalk.

Turtle shells evolved over the course of 300 million years, but self-defense wasn't the initial driver, researchers think.

It may still be an uncomfortable subject for some, but periods are a real thing that people need to manage. But what do astronauts do in space? Well, they have some options, but now they may have one more.

The two have a brilliant response to the "3I/ATLAS is an alien spacecraft" hypothesis.

Just a handful of companies can make cadmium zinc telluride, a material with powerful properties.

The animal, recently spotted in the depths of Monterey Bay, can reach lengths of 13 feet and weigh up to 165 pounds.

Liftoff of the suborbital NS-37 mission is scheduled for 9:30 a.m. ET on Dec. 18.

Physicists at the University of Colorado Boulder have designed a new material for insulating windows that could improve the energy efficiency of buildings worldwide—and it works a bit like a high-tech version of Bubble Wrap.

Two new stars, or nova eruptions, have been resolved in unprecedented detail by six optical telescopes operating in unison as an interferometer.

The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of life-sustaining substances for future astronauts. But scientists ha…

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent  study using NASA’s Chandra X-ray Observatory. This

This video by Ian Lauer is an excellent accessible explanation of the basics of astrophotography as he runs through the process

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt.
