Although it gave no real indication of how life in fact first evolved, the experiment left astrobiology with a framework for investigating the chemistry of alien worlds. In 1975, the first Mars ...

Twice the size ... life on our planet, and this has led scientists to believe that K2-18b may have life forms in its hydrogen-dominated atmosphere and potential oceans. K2-18b discovery fuels ...

The exoplanet K2-18b is generating headlines because researchers announced what could be evidence of life on the planet. The JWST detected a pair of atmospheric chemicals that on Earth are produced by ...

"When a discovery is as monumental as the discovery of alien life, the bar is set very high for convincing evidence," said Genge. "As a geologist who studies planets, I question the assumption ...

They used Nasa’s James Webb Space Telescope to analyse the chemical composition of the planet’s atmosphere and say they found promising evidence K2-18b could host life. It’s an exciting breakthrough ...

There is no question about it that K2-18b will be one of the targets of these new telescopes, now that the Webb designated it (again) as a potential home for alien life.
