Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...

Every planet in the solar system leans, some gently, some dramatically, and that tilt quietly shapes everything from our ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Scientists using NASA's James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it ...

Exoplanet PSR J2322-2650b, orbiting a pulsar, possesses an unprecedented helium-and-carbon-dominated atmosphere, characterized by molecular carbon (C3 and C2) and soot clouds, a composition unlike any ...

Astronomers have identified a vast, cotton-candy–light “super‑puff” world that loops around its star in a wildly misaligned ...
