NASA’s James Webb Space Telescope uncovers ‘boiling ocean’ exoplanet – could it harbour life?
[ad_1]
In a groundbreaking discovery, NASA's James Webb Space Telescope (JWST) has revealed intriguing details about a distant exoplanet, sparking a debate among scientists about its potential habitability. The exoplanet, known as TOI-270 d, lies approximately 70 light-years away and boasts twice the radius of Earth.Observations from the James Webb Space Telescope exposed the presence of water vapour, methane, and carbon dioxide in the exoplanet's atmosphere, suggesting a composition consistent with a colossal water world. Researchers from the University of Cambridge propose that an entire surface ocean, potentially reaching temperatures exceeding 100 degrees Celsius, envelops TOI-270 d. However, they caution against envisioning this as an inviting seascape, emphasizing the extreme cond...
