– January 7, 2026 (London time) – One of the biggest recent surprises in astronomy is the discovery that most stars like the Sun harbor a planet between the size of Earth and Neptune within the orbit ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. Earth-like ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

Planets orbiting stars beyond the solar system come in all shapes and sizes but mostly fit into a few categories: large and hot gas giants, super-Earths that are slightly larger than our planet, ...

Nearly all of the planets in the solar system are about to march through the night sky in a single-file line. This planetary alignment, sometimes called a planet parade, will include all of the solar ...
