Scientists predict that Earth's atmosphere will transform back to a methane-rich state in about a billion years, drastically reducing oxygen levels and threatening life as we know it. This shift could happen rapidly, returning the planet to conditions reminiscent of its early history, long before human existence. What does this mean for our search for life beyond Earth?
Astronomers from the University of Cambridge have found compelling evidence of potential life on exoplanet K2-18b, using data from the James Webb Space Telescope. Their findings suggest the presence of chemical traces linked to biological activity, igniting excitement and skepticism in the scientific community.
The LIFE mission aims to explore rocky exoplanets in habitable zones to assess the likelihood of life beyond Earth. Even without finding life, it could change our understanding of planetary habitability.
