Earlier this year, astronomers reported possible evidence of life on another planet – but new observations from JWST suggest ...

Data from the James Webb Space Telescope on exoplanet K2-18b has revealed the "strongest hints yet of biological activity ...

Recently, researchers allegedly found signs of life on an exoplanet. New research data now makes this seem very unlikely.

A paper published in 2023 spurred discussion about whether life exists on an exoplanet named K2-18b. Two years later, the puzzle continues — and some scientists are expressing doubt.

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." ...

New observations fail to confirm signs of life in the atmosphere of the distant planet K2-18b. They also raise questions about what it will take to detect biology light-years away.

K2-18b, located 124 light-years from Earth, could be a Hycean world: a potentially habitable planet entirely covered in liquid water with a hydrogen-rich atmosphere, said lead study author Nikku ...

The planet in question, K2-18b, was discovered in 2015 by NASA's Kepler mission, which revealed that planets outside our solar system are so common that they outnumber stars.

Madhusadhan, Hu and their colleagues used JWST’s near-infrared camera to look at the light from K2-18b’s star, which, after passing through the planet’s atmosphere, can tell us about what ...

K2-18b has a mass 8.6 times that of Earth’s, and the planet is 2.6 times as large as Earth. Scientists have had their eye on this planet for a few years now.
