An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar ...

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, ...

"Without it, we might not have Earth as we know it."Using computer simulations, Izidoro and his colleagues modeled how ...

Researchers are studying eccentric warm Jupiters, giant exoplanets that follow odd, elongated orbits unlike anything in our solar system.

Scientists have discovered that a distant "hot Jupiter" world has a planetary companion. The two planets are locked in a rhythmic dance around the star TOI-1408, located 455 light-years from Earth.

Earth, called Ross 508 b, orbiting a small red dwarf star just 37 light-years from Earth. The discovery, made using the ...

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 ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit ...

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 ...
