Scientists have long wondered why carbon-rich meteorites appear less affected by violent impacts than those lacking the stuff. They may finally have an answer.

Valleys on Mars suggest the Red Planet was once covered in flowing water — but it's still a mystery how that could have been.

Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.

NASA's Curiosity rover has found iron-rich carbonates on Mars — a major clue that the Red Planet used to be habitable.

Scientists are developing an advanced quantum sensor for low Earth orbit that can detect the tiniest tremors in Earth's gravity.

Alien life could exist on the huge Saturn moon Titan, but probably not in the abundance scientists once hoped, according to a new study.

The sun was caught bursting out a huge quantity of helium-3, an isotope that's scarce in our solar system.

Scientists were watching for changes in bird vocalization patterns during the 2024 total solar eclipse. Here's what they found.

New insights into the chemistry of exoplanet atmospheres indicates planet-wide rainfall might take place following hydrogen atmosphere and water mixing.

Scientists are probing stellar "quakes" to understand what lies beneath the surface of a star's body.

A massive solar windstorm in 2017 compressed Jupiter's magnetosphere "like a giant squash ball," a new study reports.

Understanding exoplanet evolution could help solve the mystery of the 'hot Neptune desert.'

The JWST was used in a creative way to capture direct images of distant worlds.

Using the James Webb Space Telescope, astronomers have captured direct images of Neptune's elusive auroras for the first time.

A cosmic coincidence has led to one of the most amazing images ever captured by NASA’s James Webb Space Telescope.

Astronomers have tracked several meteorites that dropped in on Earth back to their origin, space rocks in the main asteroid belt between Mars and Jupiter.

A new model that incorporates data gathered by the JWST could help scientists understand the composition and mass of objects in the distant Kuiper Belt and beyond.

The Mars water debate continues. A team of scientists suggests vast oceans of water may not be locked within the Red Planet's crust, despite InSight lander data.

The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a blistering 19-hour orbit.

Astronomers have used near-infrared light to explore the extreme forces behind the eruption of LMC68, a recurrent nova in the Large Magellanic Cloud.

A major milestone with the Vera C. Rubin Observatory has been reached with the installation of the telescope's enormous eye — the world's largest digital camera.

Scientists think geysers on Saturn's moon Enceladus might come from a "mushy" zone of ice along the world.

Mars is known as the "Red" Planet, but what actually makes it red? New research offers answers.

Technicians have installed the sunshade on NASA's Nancy Grace Roman Space Telescope, which is scheduled to launch in Spring 2027.

Scientists are cataloging and analyzing the first samples collected by NASA's Perseverance rover while the agency weighs its options for returning them to Earth.
