Life on Exoplanet? Webb Detects Key Chemicals! #shorts

[00:00:00]British American team using the James Webb Space Telescope discovered signs of two chemicals in the planet's atmosphere. Dimethyl sulfide and dimethyl dissulfide on Earth. These chemicals are produced exclusively by living organisms, particularly by tiny marine algae known as phytolanton.

[00:00:19]This discovery could have significant implications and astrophysicists believe it is the closest we have come to detecting something we can link to life.

[00:00:28]The latest breakthrough follows a 2023 study in which the web telescope detected methane and carbon dioxide in the atmosphere of K218b.

[00:00:38]This marked the first discovery of carbon-based molecules in an exoplanet located within a habitable zone.

[00:00:44]Additionally, the telescope recorded weak signals of dimethyl sulfide, which led astronomers to conduct further observations of the planet last year using a different instrument.
