The outer planets of the solar system are swarmed by ice-wrapped moons. Some of these, such as Saturn's moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky core and could be the best places in our solar system to look …

Skylights, openings in the surface of Mars that descend down into caves, have been found on Mars, along with signatures for the presence of water ice.

The cool part about science is that you can ask questions like what happens if you stick some moss spores on the outside of the International Space Station, and then get funding for answering said …

In anticipation of Thanksgiving, I have received over the past day the following letters of gratitude concerning the interstellar object…

The James Webb telescope may have detected the universe's earliest and most distant known black hole at the heart of galaxy GHZ2, revealing how the first black holes grew just a few hundred million years after the Big Bang.

A novel magnetic material with an extraordinary electronic structure might allow for the production of smaller and more efficient computer chips in the future: the p-wave magnet. Researchers from Karlsruhe Institute of Technology (KIT) were involved in its de…

Scientists discover 580,000 years of dramatic climate changes hidden in a Nevada cave, offering a chilling glimpse into the future of the Southwest as temperatures rise and water dwindles.

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the first time six distinct planetary tectonic regimes and identi…

An ancient fossil has revealed that the ancestors of coffee and potatoes survived the great extinction. How did these plants make it through?

It is a scientific consensus that water once flowed on Mars, and that it had a denser atmosphere, meaning that it was once habitable.

NASA released new images of 3I/ATLAS, the third comet ever to be discovered in Earth's cosmic neighborhood originating from elsewhere in the universe.

Comet C/2025 K1 (ATLAS) fractured following a close brush with the sun on Oct. 8.

A monumental fossil find in India has revealed a snake of unimaginable proportions.

At minus decibels, visitors have reported being able to hear the blood pumping through their veins and arteries.

New research using numerical relativity might finally reveal the secrets of the Big Bang—and what happened before it.

In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

A bear that could run faster than most humans, weighed over a ton, and stood taller than any bear alive today—sounds like something from a monster movie, right?

This week’s puzzle was constructed by Evan Mulvihill and Rafael Musa, and edited by Hoang-Kim Vu. Evan is a cruciverbalist living in San Francisco, Calif. His crosswords have been published by the New York Times, the Wall Street Journal and Los Angeles Times.…

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can be manufactured on silicon chips.

One rover, who looks like WALL-E, hunted water. The other rover did a pew-pew.

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel from them over to here, but in that intervening time, the un…

The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

NASA's Voyager 1 and 2 are the longest-running missions in the space agency's long history of historic achievements.

A deadly conflict between rival groups of chimpanzees in Uganda led to comprehensive victory and a bounty of territory and food — does it show why humans go to war?

European astronomers report the discovery of a second alien world in the TOI-1422 planetary system located some 500 light years away. The newfound exoplanet, which received designation TOI-1422 c, is nearly three times larger and about 14 times more massive t…
