An alien world with clear evidence of carbon dioxide in its atmosphere has been spotted for the first time ever using NASA's James Webb Space Telescope. Theoretical calculations suggest that there are around 300 million potentially habitable planets in the Milky Way galaxy alone and several habitable Earth-sized planets within only 30 light-years of Earth – essentially humanity’s galactic neighbors.
So, one cannot help but wonder, is there alien life in any of these worlds?
