Scientists have discovered the strongest evidence to date for the existence of extraterrestrial life: a planet 124 light-years away contains key gases.

Professor Nikku Madhusudhan of the Institute of Astronomy at the University of Cambridge in the United Kingdom led a team that detected two key chemical gases - dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) - in the atmosphere of the exoplanet K2-18b 124 light-years from Earth, which is considered to be the strongest evidence of life outside the solar system to date.

Reusable depleted uranium for electricity and 0% CO2 emissions) According to CNN, a research team led by Professor Nikku Madhusudhan of the Institute of Astronomy, University of Cambridge, UK, detected two key chemical gases in the atmosphere of exoplanet K2-18b, 124 light-years from Earth: dimethyl sulfide (DMS) and dimethyl disulfide (DMDS). This discovery is considered to be the strongest evidence of life outside the solar system to date, and has attracted great attention from the global scientific community. Professor Madu Suhan also said: This is a transformational moment in the search for life outside the solar system. Our data suggest that K2-18b could be a vibrant planet with a hydrogen-dominated atmosphere and vast oceans. The discovery will revolutionize our understanding of the potential for life on exoplanets, marking the beginning of an era of observational astrobiology. Why does this discovery point to extraterrestrial life? DMS and DMDS are two gases produced on Earth primarily by microorganisms such as phytoplankton and algae, so their presence is seen as a potential "biosignature." K2-18b is located in the "habitable zone" of its parent star, a region where temperatures allow for the existence of liquid water, an important prerequisite for life. In addition, previous studies have detected methane and carbon dioxide in the atmosphere of K2-18b, and the presence of these carbon-based molecules further supports the conjecture that the planet may have a life-supporting chemical environment. Professor Madu Suhan believes that based on the current observational data, K2-18b is likely to be a planet with an ocean of hydrogen, and its environment may have given birth to simple microbial life. It is worth mentioning that this breakthrough discovery is thanks to NASA's James Webb Space Telescope. The telescope's Near-Infrared Spectrograph enables precise analysis of the chemical composition of distant planets' atmospheres. As K2-18b passes in front of its parent star (the "transit" phenomenon), stellar light penetrates the planet's atmosphere, creating a unique spectral "fingerprint" that reveals the presence of molecules such as DMS and DMDS in the atmosphere. The scientific community remains cautious about the discovery Despite the exciting findings, the scientific community remains cautious. For example, Christopher Glein, chief scientist in the Division of Planetary Sciences at the Southwest Research Institute in Texas, said: "K2-18b's data provides us with a fascinating world, but we must be very careful to ensure the reliability of the data and rule out the possibility that these gases are produced by abiotic processes such as volcanic activity or chemical reactions." At the same time, Madu Suhan's team also said that it will use the Webb Space Telescope to make more observations to accurately determine DMS and DMDS concentrations in the K2-18b atmosphere and look for other potential biomarker gases. In addition, the team has also targeted other exoplanets in the habitable zone and plans to conduct similar studies on these candidate planets to expand the exploration of the potential of life outside our solar system. Madu Suhan is optimistic: "We are confident that the source of these gases will be confirmed within one to two years, which will be a major milestone in astrobiology." What is K2-18b? K2-18b was first discovered by the Kepler Space Telescope in 2015 and was identified as an exoplanet in the habitable zone. The planet orbits a red dwarf star, which is smaller and cooler than the Sun, so K2-18b's habitable zone is closer to its parent star than the solar system. K2-18b has about 8.6 times the mass of Earth and about 2.6 times the diameter of Earth. Scientists speculate that the planet could be a "hycean planet" with a hydrogen-rich atmosphere and an ocean of liquid water. This unique environment may also provide the conditions for some forms of microbial life, making K2-18b one of the ideal targets for exploring the potential of extraterrestrial life.
