Using JWST, scientists discovered PSR J2322-2650b — a carbon-rich, lemon-shaped exoplanet orbiting a pulsar — challenging ...

As shocking as it sounds today, prior to the 1990s, scientists couldn't be certain that stars beyond the sun also had planets orbiting them. Since the discovery of the first extra-solar planet, or ...

Pluribus imagines Kepler-22b as an ocean world that sends a gift to humanity through radio waves. In real life, no such ...

From Viking to Perseverance, scientists have spent decades chasing chemical hints that could point to life beyond Earth.

NASA’s James Webb Space Telescope has found the strongest evidence yet that a small, rocky planet outside our solar system has air, even though it orbits precariously close to its star. The exoplanet, ...

Scientists have used data from NASA's retired planet-hunting space telescope 'Kepler' to discover that small and large worlds have very different upbringings. The team found that larger planets on non ...

Life may not get blasted off any of the known "super-Earth" worlds as readily as it can from our planet, scientists find. The discovery suggests that any intelligent aliens that develop on such ...

WASHINGTON (Reuters) - Astronomers have spotted orbiting around a young star a newborn planet that took only 3 million years to form - quite swift in cosmic terms - in a discovery that challenges the ...

An ocean world that’s teeming with microbes — and who knows what other kinds of life — is currently the best explanation for some chemical signatures that the James Webb Space Telescope has spotted in ...

Astronomers using the Hubble Space Telescope have for the first time directly detected the atmosphere of a planet outside our solar system. The unique observation shows it may be possible to find ...
