Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Space is full of mysteries that can't be easily explained by the layman, and this latest one from a isn't likely to sour anyone on their fascination with space. Scientists from several institutions, ...

When astronomers announced Kepler-452b, they were not just adding another distant world to a growing catalog. They were ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

Researchers estimate that the planet has about a 50% chance of being in its star's Hoble zone.

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...
