The world's largest optical telescope is still under construction but is raising the roof on its progress.

Quantum time travel is now possible for particles, using a rewind protocol that reverses time flow without knowing a system’s history.

Serendipitously and for the first time, an international research team led by scientists at the U.S. Department of Energy's SLAC National Accelerator Laboratory formed solid binary gold hydride, a compound made exclusively of gold and hydrogen atoms.

Dr. Spencer Pelton and his colleagues have conducted a comprehensive analysis of the River Bend site (48NA202), Wyoming. The site, located near the North Platte River in Casper, Wyoming, was excavated in the 1970s as part of salvage efforts prior to construct…

One of the most colorful and best meteor showers of the year is about to leave colorful streaks across the black backdrop of space as its peak approaches.

Quantum computers have the potential to solve problems far beyond the reach of today's fastest supercomputers. But today's machines are notoriously fragile. The quantum bits, or "qubits," that store and process information are easily disrupted by their enviro…

A 2024 astronaut photo shows a rare "sunglint" shining off Lake Iro and a nearby zig-zagging river in Chad. The shimmering bodies of water were likely both shaped by an ancient meteor impact.

Starting in 2013, a wasting disease caused a mass die-off from Mexico to Alaska, devastating more than 20 species.

At the end of July, hundreds of scientists convened to plan NASA's upcoming astrophysics flagship mission. Will the US allow it to happen?

The moon is nice and bright tonight.

A rare fossil in Dominican amber unveils a miniature, ancient “dirt ant” once native to the Caribbean. Ants are a common sight wherever soil is found, but one group is so expertly camouflaged that they have earned the exclusive name “dirt ants” (Basiceros). A…

Antarctica’s deep canyons shape oceans and climate. High-resolution maps show striking regional differences. Submarine canyons rank among the most striking and complex geological structures on the ocean floor, yet many remain poorly understood, particularly t…

This is really starting to get petty Sean and Brian

The ‘hot blob’ is officially called Northern Appalachian Anomaly (NAA), and lies 125 feet deep underground and extends 220 miles across New England.

The image reveals over 2,500 galaxies, many of which are seen as they were during the first billion years of cosmic history.

Some mice were more adept at seeking water after the gene change, signaling a behavioral change and potential cognitive advantage.

After Earth’s greatest extinction, it wasn’t just volcanic fury that kept the planet hot; it was the death of tropical forests that turned off the planet’s cooling system, leading to millions of years of scorching heat.

“We will be ready for them when they’re ready to fly.”…

Footage from the BBC's new nature series "Parenthood" shows orcas practicing an important blue whale-hunting technique on each other.

A collection of dinosaur teeth hailing back to the Cretaceous and Jurassic periods has given scientists a new window into the world's prehistoric climate.

Early human ancestors may have lived in societies more combative than anything today.

The observed and forecasted growth rate of paper mill papers outpaces corrective measures, a new study finds. R. Richardson et al./PNAS 2025 Systematic research fraud has outpaced corrective measur…

Curiosity viewed this rock shaped like a piece of coral on July 24, 2025. The rover has found many rocks that were formed by minerals deposited by ancient water flows.

Researchers have discovered that it’s possible to speed up, slow down, or reverse the flow of time in a quantum system.
