The new TRACERS mission will track magnetic reconnection that drives particles down into Earth's atmosphere when space weather turns bad.

Soil excavated from the moon could be used to produce oxygen and methane, which could be used by lunar settlers for breathing and for rocket fuel.

The basaltic meteorite is a piece of lunar rock that formed in a lava flow 2.35 billion years ago, long after volcanism on the moon was supposed to have ended.

"Our work is a new piece of evidence that suggests that Mars was once a much more complex and active planet than it is now."

The impact that carved out the moon's huge South Pole-Aitken basin may explain the puzzling differences between the lunar near and far sides.

The U.S. government's "One, Big Beautiful Bill" Act finds funding for Artemis and Lunar Gateway, but nearly half of NASA's science missions are on the chopping block ahead of the 2026 budget.

Planetary construction sites around other stars are filled with pebbles, and for the first time radio telescopes have detected these tiny chunks of rock that stick together to form planets.

Scientists had assumed that the ice in space was purely amorphous, but new experiments show it can have a partly crystalline structure similar to ice on Earth.

"You can think of it as a cosmic pool game. We might miss the pocket if we don't consider all the variables."

"We know that some microbes on Earth can tolerate the range of pH found on Enceladus."

The discovery could explain why younger stars seem to have more lithium than the Big Bang theory says they should have.

The spacecraft now almost tips upside down relative to Mars to give its radar the best view.

In the latest attack on science by the Trump administration, researchers at the National Snow and Ice Data Center will no longer receive data from a fleet of military satellites.

It's another step on the road to one day discovering what dark matter could be.

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked up in rocks.

"Its occurrence is like finding a tropical seed in Arctic ice – indicating either an unexpected local environment or long-distance transport in the early solar system."

The amount of data generated by the Rubin Observatory is going to blow all previous cosmic datasets out of the water, but handling that much information poses a severe challenge.

Breathing in moon dust can still give you what one astronaut called "lunar hay fever."

The beads are over 3.3 billion years old, and date from the formation of the "Man in the Moon."

Part of the closest star-forming region to us, known as the Chamaeleon Complex, has been illuminated by the light of young stars in this artwork by nature captured by the Dark Energy Camera.

Simultaneously cooling Pluto while energizing atmospheric molecules to allow them to escape into space, Pluto's haze plays a key role in the planet's energy balance.

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

A giant exoplanet is surprisingly chill given how close it is to its red dwarf star — perhaps because the star is so little.

Built on a set in a specialist facility in Germany, a mockup of a lunar landscape is helping imaging experts learn how to take better images and video footage on the moon.

The core of the Red Planet may be filled with sulfur.
