By analyzing the disintegrated remains of distant worlds consumed by their stars, a new study found that at least some rocky exoplanets may have interiors similar to those of Earth and Mars.

New infrared cameras and gel-based thrusters just might help future satellites dodge space debris, a new study finds.

The most magnetic stars may have their origins in merging stars, a new study finds.

NGTS-10b is a very weird world.

The faintly glowing wisps of gas that make up the intergalactic filaments of a universe-spanning cosmic web may have finally been detected for the first time, a new study reports.

Alien worlds resembling giant eyeballs might be able to host life, but they may not be as common as previously suggested, a new study finds.

Astronomers have discovered a giant, Jupiter-like planet in an unexpected location, and it's orbiting a small, nearby red dwarf star, a new study finds.

More mysteriously dimming stars have been spotted.

What might it take to feed a million people on Mars? Lab-grown meat, tunnel-grown crops and cricket farms, a new study finds.

Astronomers have discovered the most massive example yet of the dead stars known as neutron stars, one almost too massive to exist, a new study finds.

Warps in the fabric of space-time can act like magnifying glasses, and that may help solve a cosmic mystery about the rate of the universe's expansion, a new study found.

The birthplace of two meteorites from Mars was apparently a zone with two craters: new findings that scientists might use to unlock secrets on the Red Planet.

This one involved the Milky Way's supermassive black hole.

Ceres, the closest dwarf planet to Earth, may be wrinkling as it shrinks.

A storm of cosmic impacts may have ended relatively early on Mars, suggesting that the Red Planet was habitable longer than scientists previously thought, a new study finds.

The Red Planet may be more habitable than previously thought.
