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 ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star’s surface and rapid changes tied to its rotation. By combining ...

Add Yahoo as a preferred source to see more of our stories on Google. Some exoplanets, like the one shown in this illustration, may have atmospheres that could make them potentially suitable for life.

Astronomers have identified a vast, cotton-candy–light “super‑puff” world that loops around its star in a wildly misaligned orbit, defying the tidy rules that usually govern planetary systems. Instead ...

NASA’s Transiting Exoplanet Survey Satellite has identified TOI-4616 b, an Earth-sized planet transiting a cool M4 dwarf star in the solar neighborhood. The discovery, detailed in a new preprint, adds ...

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 ...

Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Artist's rendition of the space weather around M dwarf TIC 141146667. The torus of ionized gas is sculpted by the star's magnetic field and rotation, with two pinched, dense clumps present on opposing ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a planet too close to ...
