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

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

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, ...

Astronomers are abuzz with the discovery of a rogue planet, 2MASS J05325346+0919037, which is set to pass within 0.05 ...

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

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 ...

Many scientists call Jupiter the architect of the solar system because its immense gravity influenced the orbits of other ...

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

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 ...

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, ...

Jupiter's rapid early growth dramatically reshaped our solar system, scientists now reveal. Its immense gravity acted as a ...
