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 from us. In astronomical terms, that’s right next door. What’s more, it might be capable of supporting life.

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

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

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 new planet is almost the same size as Earth and swings around its home star, which is called LP 791-18, about once every three Earth days. Average temperatures there could spike to more than ...

Scientists at NASA have discovered a new Earth-sized planet orbiting the habitable zone of its star. Data from NASA’s Transiting Exoplanet Survey Satellite (TESS) revealed the planet, called TOI ...

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.

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. The planet, called LP 791-18 d, is ...

The planet was the first of a similar size to Earth discovered orbiting in a “Goldilocks zone,” or an area around a star that would not be too hot or too cold for liquid water to exist.

A team of astronomers have found a potentially habitable exoplanet about 40 light-years away in the constellation Pisces. Exoplanet Gliese 12 b is slightly smaller than Earth–about the size of ...
