Astronomers have discovered a rare lemon-shaped planet called PSR J2322-2650b orbiting a city-size star. Found using NASA’s James Webb Space Telescope, the Jupiter-size world is stretched by extreme ...

TRAPPIST-1e, an Earth-sized world in the system’s habitable zone, is drawing scientific attention as researchers hunt for ...

Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun ...

A NASA mission has spotted an Earth-size exoplanet orbiting a small star about 100 light-years away. The planet, named TOI 700 e, is likely rocky and 95% the size of our world. The celestial body is ...

Using publicly available data from NASA’s Kepler space telescope, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) estimate that six percent of red dwarf stars in the galaxy have ...

The James Webb Space Telescope has caught a distant world in the act of falling apart, its outer layers peeling away into space as a vast cloud of helium. The planet, a so‑called “super‑puff” with the ...

An analysis of the first three years of data from NASA’s Kepler mission, which already has discovered thousands of potential exoplanets, contains good news for those searching for habitable worlds ...

Is our Milky Way galaxy home to other planets the size of Earth? Are Earth-sized planets common or rare? NASA scientists seeking answers to those questions recently revealed their discovery. “We went ...

Astronomers have discovered an Earth-size planet that is showered with so much radiation, its atmosphere eroded away long ago, leaving it bare. Life as we know it can't exist on this blistering world, ...

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in ...

NASA’s Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in ...
