NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...

The newfound exoplanet, called Kepler-139f, is a gigantic world roughly twice the mass of Neptune and 35 times the mass of ...

A new, Earth-sized planet has been discovered only 90 light-years away. In astronomical terms, that’s right next door. Moreover, it may be capable of supporting life thanks to volcanic eruptions ...

Astronomers have discovered an Earth-sized exoplanet orbiting a star with a lifespan 100 times greater than the Sun. Speculoos-3b is 55 light years away – more then 10 times further than the ...

In a new study, a team of astrophysicists, including two researchers at CU Boulder, have discovered a small and rocky world orbiting a star far from Earth—similar to our own planet, perhaps, but much ...

The James Webb telescope has made another stunning discovery -- this time of a massive planet that could potentially sustain ...

In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much ...

By the next year, Kepler had discovered another planet considered the first near-Earth-size planet in the “habitable zone” around a sun very similar to our star.

A potentially habitable Earth-size planet was discovered just 40 light-years away Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a star that is 27% of the sun’s size.

Gliese 12 b’s estimated size may be as large as Earth or slightly smaller — comparable to Venus in our solar system.

One of the smallest, coolest stars found to have planets of any kind—just 86 light-years from the solar system—appears to have an Earth-like volcanic world.
