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.

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly more than that for our moon, posing potential challenges for future crewed missions.

Scientists said the loss hinders their work and diminishes America’s leading presence on the continent. The NSF said it continues to support Antarctic research.

The planet formed 50 million years after the dinosaurs died, making it incredibly young in cosmic terms.

There’s a less than 5 percent chance that earlier anomalies can be explained by fourth neutrino “flavor.”…

Scientists analyzed artifacts from Tycho Brahe’s lab and found tungsten, an element unknown in his time, rewriting our understanding of historical alchemy.

Could mammoths have walked among us just 2,000 years ago?

"This is the first time AI has been used to help control a robot on the ISS."

A mysterious winter wonderland on Mars has been revealed, captured in stunning high-resolution images by two of the most advanced space orbiters.

Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic Forest, an international team o…

"We did the simplest thing that could be done — we just mapped them and pieced them together."

Researchers using NASA’s James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system, as

In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang—a cosmic Jekyll and Hyde that looks like any other galaxy when viewed in visible and even ultraviolet light but transforms into a c…

A molecular superfluid, high-resolution microscope and a protein qubit are on our list

This stunning image is full of young star clusters.
