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…

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

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

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.

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information processing.

It vanished beneath the ice... 8 months later, it returned with secrets no one had seen.

Holograms are created with a single OLED pixel, bringing phones and glasses closer to projecting real 3D images without the need for lasers.

Following the anomaly the spacecraft is no longer communicating with Earth, and NASA isn't sure why.

"We are only beginning to discover the true complexity of these worlds."

This past Saturday people around Lake Superior saw a long flash of sparkling white and green light trail across the night sky. Was it a meteor? Santa’s sleigh? Turns out, it was a piece of “space junk.”

The European Space Agency’s Swarm mission detected a large but temporary spike of high-energy protons at Earth’s poles during a geomagnetic storm in November. It did this not with the scientific instruments for measuring Earth’s magnetic field, but with its ‘…

Comets have tails; 3I/ATLAS has a tail, and even Mercury has one. Does Earth have a tail? Yes. Our planet also has a tail, which possibly extends to two million kilometres into space. It is present on the dark side of the planet.

Parakeets form new friendships by slowly testing how close they can safely get to unfamiliar birds. This careful process helps them avoid conflict while identifying trustworthy partners.

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from the early cosmos.

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, revealing how this essential mitochondrial enzyme degrades RNA t…

A strange X-ray signal spotted decades ago may be the result of a star that got attacked by two black holes, one after the other.

The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in the night sky. Their study, presented in Science Advances, reports on the very first observations of a swirling vortex in spacetime caus…
