Astronomers measure the speed at which the solar system is hurtling through space by mapping surrounding galaxies and ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

European astronomers report the discovery of a second alien world in the TOI-1422 planetary system located some 500 light ...

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.

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 ...

This artist’s impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter — a large, Jupiter-like exoplanet that orbits very close to its star. NOIRLab/NSF/AURA/J. da Silva ...

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, ...

The exoplanet 8 Ursae Minoris b should not exist. It orbits its host star at just half the Earth-Sun distance, and by all indications, the star should have gone through a phase in which it bloated up ...

What if Venus and Mars suddenly swapped orbits? Explore the dramatic effects on climate, gravity, and life if our neighboring ...
