As of my last knowledge update in September 2021, there had been no confirmed discovery of extraterrestrial life on another planet. However, the search for life beyond Earth has been an ongoing and active area of research, with missions to Mars and other celestial bodies continuing to explore the possibility of past or present life.
NASA’s Mars rovers, such as Curiosity and Perseverance, have been studying the Martian environment and searching for signs of past microbial life. The discovery of organic molecules on Mars and the detection of methane fluctuations have sparked excitement and furthered the interest in the possibility of life on the Red Planet.
Additionally, the study of exoplanets (planets orbiting stars outside our solar system) has expanded our understanding of potentially habitable worlds. The James Webb Space Telescope, scheduled for launch in late 2021, is expected to play a significant role in characterizing the atmospheres of exoplanets and searching for signs of life.
Since my knowledge is not up to date, I recommend checking the latest news and updates from space agencies and scientific organizations for any developments regarding the discovery of life on other planets. It’s an exciting field of research, and new findings may have emerged since my last update.
