Astronomers have apparently detected biological activity outside of the solar system. Scientists have discovered that the faraway planet, designated K2-18 b, has more than one chemical in its atmosphere that may have been produced by life organisms. However, this finding has caused a stir among astronomers across the world, particularly those who investigate biosignatures in extraterrestrial atmospheres.
According to Nature.com, K2-18 b is a smaller planet than Neptune. It is 38 parsecs above Earth.
About the discovery
Scientists from the University of Cambridge, UK, detected dimethyl sulphide (DMS) in the atmosphere of K2-18b. The DMS chemical is produced by living beings, prompting debate about the possibility of life on this distant planet. The scientists carried out their investigation using the James Webb Space Telescope (JWST). In addition, the finding occurred when a molecule was found in sunlight passing through the planet's atmosphere. Astronomers are curious about these substances because they are produced by live creatures on Earth.
This finding was originally revealed in 2023. However, fresh disclosures have emerged as a consequence of subsequent investigations into similar results. This time, the scientists employed several wavelengths and a study technique to aid in the detection of compounds on the faraway planet.
Significance of This Discovery
For decades, scientists have been interested in investigating life beyond Earth. Now that the data points to the likely presence of DMS or DMDS on K2-18 b. If verified, this would be a major victory for science. Furthermore, this discovery contributes to a better knowledge of planets in general. Overall, about 5,800 planets have been discovered around the universe.
Reason for Uncertainty by Other Researchers
Scientists are skeptical of this discovery because they question if DMS or DMDS are indeed there or if K2-18 b is barren. While some experts are skeptical about the discovery, an expert team of scientists from the University of Cambridge in the United Kingdom is working hard to establish a solid foundation to back up their claims.
