Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident. The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.

New analysis casts doubt on 'biosignatures' found on planet K2-18b toggle caption Adriana M. Gutierrez (CI Lab) /NASA-GSFC Astronomers have been poring over last week's claim of the detection of life-associated gases in the atmosphere of a distant planet named K2-18b — "the strongest evidence yet that life may exist on a planet outside our solar system," as a University of Cambridge press release put it. But already, one independent check suggests the announcement was overhyped. Jake Taylor

Using the James Webb Space Telescope, scientists have discovered the strongest signs of alien life to date — but NASA has nothing to say about it, even though the research was conducted using its flagship space telescope. Following news that a team of Cambridge astronomers had discovered the "strongest hints yet" of atmospheric biosignatures — better known as "signs of life" — on the watery exploplanet K2-18b within our galaxy's "habitable zone," the space agency has chosen not to comment.

Astronomers say they've spotted a possible sign of life in the atmosphere of K2-18b, an exoplanet 124 light-years away, using NASA's James Webb Space Telescope. As detailed in a new paper published in the journal Astrophysical Journal Letters, the international team of researchers led by University of Cambridge astrophysicist Nikku Madhusudhan says they've detected the molecule dimethyl sulfide (DMS) in the planet's atmosphere, which here on Earth — at least as far as we know — is only produced

Look alive: The James Webb Space Telescope (JWST) may have picked up signs of a potential biosignature on a steamy, ocean-covered exoplanet called K2-18b—a biosignature that, on Earth, is produced by marine life. The main character here is dimethyl sulfide, a molecule produced by many ocean denizens, but especially plankton. If the molecule is really floating around in the atmosphere of K2-18b, it raises the tantalizing possibility that something on the world might be alive. Or at least emittin

Astronomers say they've found "the most promising signs yet" of chemicals on a planet beyond our Solar System that could indicate the presence of life on its surface. Using the James Webb Space Telescope, the team found a possible 'biosignature' – the potential fingerprint of life – within its atmosphere, although they say they're remaining "cautious", and that this isn't a confirmed detection. The chemicals detected are the same as those produced by marine-dwelling organisms on Earth. The te

The search for life beyond Earth has led scientists to explore many suggestive mysteries, from plumes of methane on Mars to clouds of phosphine gas on Venus. But as far as we can tell, Earth’s inhabitants remain alone in the cosmos. Now a team of researchers is offering what it contends is the strongest indication yet of extraterrestrial life, not in our solar system but on a massive planet, known as K2-18b, that orbits a star 120 light-years from Earth. A repeated analysis of the exoplanet’s
