K2-18b, an exoplanet 120 light-years away, may be the best hope to confirm that life exists beyond Earth. Here's what to know.
Have they found life on K2-18b? The latest findings on K2-18b came from a team of researchers led by Nikku Madhusudhan, an astrophysicist at the University of Cambridge in England.
Recently, a group of scientists claimed they found possible signs of life on a planet called K2-18b. The news made headlines. Researchers said they'd detected sulphur-based gases that, on Earth ...
Signs of life on K2-18b are promising but far from definitive So, what's next? How can researchers prove that life is present on K2-18b? More data and more testing.
In 2021, K2-18b's initial atmospheric composition had led Madhusudhan and his colleagues to suggest the planet harbors a warm ocean blanketed by a hydrogen-rich atmosphere.
Even beyond K2-18b, Madhusudhan said Webb and future telescopes could allow humanity to discover life outside our home planet sooner than one might think.
Previous data of K2-18b, obtained with Webb’s Near-Infrared Imager and Slitless Spectrograph and Near-Infrared Spectrograph, shows an abundance of methane and carbon dioxide in the exoplanet’s ...
The James Webb Space Telescope may have detected life-associated gas in the atmosphere of a far-off planet. The news is being greeted with both enthusiasm and skepticism.
