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

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 ...

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

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 ...

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.

A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study. The planet is about the size of Venus ...
