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, ...

When my colleagues and I send them out to explore our solar system, it's important for us to understand the 3D map of 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 ...

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 ...

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 ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Astronomers have just confirmed one of the strangest kinds of worlds imaginable, a planet drifting through the galaxy with no ...
