The most recent planet discoveries bring the number of known exoplanets–planets outside our solar system–to 236, the researchers told a meeting of the American Astronomical Society in Honolulu on ...

The TOI-700 star system is home to four planets, including two in its habitable zone that could host liquid water. NASA's Goddard Space Flight Center Habitable planets are those that are just the ...

Spanish researchers have identified two exoplanets orbiting the red dwarf TOI-1752. One of them has emerged as a key target because it may support liquid water if its atmosphere is suitable.

A rocky world orbiting within its star’s habitable zone may be surrounded by a helium-rich atmosphere, providing the strongest evidence yet that planets with Earth-like conditions could support life ...

So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't been for lack of trying. According to a new paper by Thomas Winterhalder of ...

Researchers have discovered an atmosphere around a distant, rocky exoplanet named LHS 1140b. The planet is located in its star's "habitable zone," a distance where conditions could allow for liquid ...

Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points. A ...
