A planet that is about the size of Saturn, but with a temperature more like Earth’s, has an atmosphere rich in methane, according to a new study using NASA’s James Webb Space Telescope (JWST).

Unlike the gas giant planets—Jupiter and Saturn—in Earth’s solar system, which are distant from the sun and therefore extremely cold, and so-called “hot Jupiters”—giant planets beyond the solar system that are s...

A hidden magnetic twist inside the Milky Way may rewrite what scientists know about how our galaxy is held together. Astronomers have uncovered a strange magnetic “flip” hidden inside the Milky Way. Using a new radio telescope, researchers mapped the galaxy’s magnetic field in unprecedented detail and discovered that a mysterious reversal in the Sagittarius Arm cuts diagonally across space. The finding could reshape how scientists understand the structure and future evolution of our galaxy.

For hundreds of years, astronomers have studied the night sky in an effort to understand ...

Some animals can move efficiently beneath granular surfaces. These include the sandfish (Scincus scincus), a lizard native to the Sahara. It can burrow into the sand and then literally “swim” through the desert sand to hunt or escape predators.

The principles of movement underlying this ability have only been understood for a few years. Researchers at the University of Würzburg have now translated the sandfish’s locomotion mechanism into an initial technical solution—an innovative Mars rover that outperforms other models when moving on sand.

The team led by computer scientist Marco Schmidt, Professor for Embedded Systems and...

Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 million light-years and links two galaxies from nearly 12 billion years ago...
