A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away. The planet, known as HD 20794d, gets farther out from its star than Mars is from ...

HD 20794 d is expected to be a focal point for upcoming projects like the Extremely Large Telescope, the Habitable Worlds Observatory, and the Large Interferometer For Exoplanets (LIFE). These ...

Researchers have discovered an Earth-like planet with such an eccentric orbit that it swoops in and out of its habitable zone throughout its year. Though the super-Earth could theoretically be ...

NASA says researchers studying exoplanets in space using the TESS space telescope have discovered a super-Earth orbiting its red star's habitable zone. Scientists say one "year" of its orbit would ...

UK researchers have confirmed the existence of a “super-Earth” located 20 light-years ... scientists because its trajectory places it in a habitable zone, meaning it is at the right distance ...

Using that number, astronomers estimate that there are tens of billions of super-Earths in habitable zones where liquid water can exist in the Milky Way alone. Since all life on Earth uses water ...
