Exoplanet K2-18b

Scientists have found new but tentative evidence that a faraway world orbiting another star may be home to life. A Cambridge team studying the atmosphere of a planet called K2-18b has detected signs of molecules which on Earth are only produced by simple organisms. K2-18b is two and a half times the size of Earth and is seven hundred trillion miles away from us. This is the second, and more promising, time chemicals associated with life have been detected in the planet's atmosphere by Nasa's James Webb Space Telescope (JWST). But the team and independent astronomers stress that more data is needed to confirm these results.

In a groundbreaking discovery, scientists have detected two bio-indicator gases—dimethyl sulfide and demethyl disulfide—on exoplanet K2-18 b. These molecules are often associated with life on Earth, raising exciting possibilities about extraterrestrial life. #universe #alien #earth About Channel: WION The World is One News examines global issues with in-depth analysis.

Scientists from Cambridge University have identified strong signs of alien life using the James Webb Space Telescope on exoplanet K2-18b, roughly 1.17 quadrillion kilometers from Earth. Two gasses have been found on the exoplanet, dimethyl sulfide and dimethyl disulfide, and were thought to have only been generated on Earth by algae and microscopic plants. “We have found possible biological activity on an exoplanet … this is one of the biggest questions we have asked as a species in science,” University of Cambridge scientist Nikku Madhusudhan said. “We have to deal with it very carefully in that we want to be really, really robust in establishing that this is actually life that we are seeing.” 1.17 quadrillion kilometers is around 123.67 light years.

British scientists say they've discovered the strongest evidence so far of life beyond our solar system. They’ve found gases on a distant planet which, on Earth, are only generated by living organisms. Al Jazeera’s Wilson Dizard explains.

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious. Using data from the James Webb Space Telescope (JWST), the astronomers, led by Professor Nikku Madhusudhan from the University of Cambridge, have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), in the atmosphere of the exoplanet K2-18b, which orbits its star in the habitable zone. On Earth, DMS and DMDS are only produced by life, primarily microbial life such as marine phytoplankton. While an unknown chemical process may be the source of these molecules in K2-18b’s atmosphere, the results are the strongest evidence yet that life may exist on a planet outside our solar system. The observations have reached the ‘three-sigma’ level of statistical significance – meaning there is a 0.3% probability that they occurred by chance. To reach the accepted classification for scientific discovery, the observations would have to cross the five-sigma threshold, meaning there would be below a 0.00006% probability they occurred by chance. The researchers say between 16 and 24 hours of follow-up observation time with JWST may help them reach the all-important five-sigma significance. While they are not yet claiming a definitive discovery, the researchers that with powerful tools like JWST and future planned telescopes, humanity is taking new steps toward answering that most essential of questions: are we alone?
