Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit ...

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, ...

An international team of astronomers has identified a rare, potentially habitable super-Earth just 19.5 light-years from ...

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 ...

A tool called AI-Newton can derive scientific laws from raw data, but is some way from developing human-like reasoning.

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...

EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...

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 ...

Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...

While Earth is currently the only planet known to support life, astronomers look for certain factors that hint when a newly discovered exoplanet, or planet outside of our solar system, could be ...
