  Scientists Find Strongest Evidence Yet Of Life On An Alien Planet

  Apr 17, 2025, Cambridge, England, United Kingdom: Professor NIKKU MADHUSUDHAN from Cambridge‘s Institute of Astronomy, who led the research. 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 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...、クレジット：©Ａｔｌａｎｔｉｃ　Ｓｔｕｄｉｏｓ／Ｃａｍｂｒｉｄｇｅ　Ｕｎｉｖｅｒｓｉｔｙ／ＺＵＭＡ　Ｐｒｅｓｓ／共同通信イメージズ

  Scientists Find Strongest Evidence Yet Of Life On An Alien Planet

  Apr 17, 2025, Cambridge, England, United Kingdom: The graph shows the observed transmission spectrum of the habitable zone exoplanet K2-18 b using the JWST MIRI spectrograph. The vertical shows the fraction of star light absorbed in the planet‘s atmosphere due to molecules in the planet‘s atmosphere. The data are shown in the yellow circles with the 1-sigma uncertainties. The curves show the model fits to the data, with the black curve showing the median fit and the cyan curves outlining the 1-sigma intervals of the model fits. The absorption features attributed to dimethyl sulphide and dimethyl disulphide are indicated by the horizontal lines and text. The image behind the graph is an illustration of a hycean planet orbiting a red dwarf star.

  Scientists Find Strongest Evidence Yet Of Life On An Alien Planet

  Apr 17, 2025, Cambridge, England, United Kingdom: An illustration shows a hycean world, an exoplanet with a liquid water ocean beneath a hydrogen-rich atmosphere, orbiting a red dwarf star. Based on observations by the James Webb Space Telescope, the exoplanet K2-18 b might fit in this category.
