A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

Small size seems to have come before a change in diet for a tiny dinosaur lineage.

Buried deep within one egg, scientists uncovered a rare internal feature that could rewrite what we know about how titanosaurs laid their clutches.

NASA's James Webb Space Telescope reveals new infrared images of the brain-shaped PMR 1 "Exposed Cranium" nebula, the final stages of a dying star.

Many mammals have fur the color of brown and black. Why don't they have more exotic colors, like purple and neon pink?

A 12th-century sword spotted jutting out of the seabed in Israel was designed for one-handed combat during the Crusades.

Astronomers have discovered TOI-5734 b, a hot sub-Neptune planet twice the size of Earth, offering new insights into planetary evolution.

Scientists mapped a hidden "sea of light" from hydrogen 9–11 billion years ago, revealing how the early universe was structured.

This stunning satellite image of Ouarzazate, Morocco, was taken by Europe's Copernicus Sentinel-2 mission.

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing estimates of the universe's age rather than its expansion rate. …

Deep within the planet's violent, globe-spanning dust storms, something unexpected is happening. A specialized sensor just captured a rare phenomenon that changes everything we know about the Martian sky.

A brainless marine creature exposes an ancient body-building system once believed unique to complex life.

In some parts of the world, more than a billion years of geologic history is missing. Now a team of scientists think they know why.

How does a single cell reliably build one of the most complex structures known in nature? New research suggests the answer may not depend solely on chemical signals, as long assumed.

A startup wants to light up the night sky using giant mirrors in space. The idea could extend daylight for solar farms and nighttime operations.

Antscan is a publicly accessible database of synchrotron X-ray CT images of ants. The database covers almost 800 species from more than 200 genera and is coordinated with genome sequencing projects that will enable integrative analyses.

A week ago, the Rubin Observatory initiated the release of its much-anticipated flood of data from its 3.2 gigapixel camera (as announced…
