Mercury helps to detail Earth's most massive extinction event

The Latest Permian Mass Extinction (LPME) was the largest extinction in Earth's history to date, killing between 80–90% of life on the planet, though finding definitive evidence for what caused the dramatic changes in climate ...

Scientists unveil a unified theory for rocky planet formation

A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than Earth that are the most abundant type of planet in the galaxy.

James Webb Space Telescope confirms its first exoplanet

Researchers have confirmed the presence of an exoplanet, a planet that orbits another star, using the NASA/ESA/CSA James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly ...

Shift to ultraviolet-driven chemistry in planet-forming disks marks beginning of late-stage planet formation

The chemistry of planet formation has fascinated researchers for decades because the chemical reservoir in protoplanetary disks—the dust and gas from which planets form—directly impacts planet composition and potential for ...

Are planets tidally locked to red dwarfs habitable? It's complicated

Astronomers are keenly interested in red dwarfs and the planets that orbit them. Up to 85% of the stars in the Milky Way could be red dwarfs, and 40% of them might host Earth-like exoplanets in their habitable zones, according ...
