Astronomers have detected what may be the strongest evidence yet of #extraterrestrial life on K2-18b, a massive exoplanet orbiting a star 120 light-years from Earth. Using the #JamesWebb #Space Telescope, researchers found significant concentrations of dimethyl sulfide and dimethyl disulfide in K2-18b's atmosphere. On #Earth these sulfur compounds are exclusively produced by living organisms, particularly marine algae. npr.org/2025/04/16/nx-s1-53648

Das riecht nach außerirdischem Leben auf K2-18 b! 👃🌊

Auf dem 124 Lichtjahre entfernten Exoplaneten wurden deutliche Spuren von Dimethylsulfid (DMS) und Dimethyldisulfid (DMDS) gefunden – beides Stoffe, die auf der Erde nur von Organismen produziert werden und für den typischen Geruch des Meeres sorgen.

Primul studiu care confirmă posibilitatea existenței vieții organice, pe o planetă îndepărtată din #ConstelațiaLeului. Cu ajutorul telescopului spațial #JamesWebb, oamenii de știință au determinat că atmosfera acesteia conține două gaze specifice care pe 🌍#Terra sunt produse doar de algele marine. Prezența unei activități biologice rămâne însă o ipoteză.

Astronomers detected potential signs of life on exoplanet K2-18b, 124 light-years away in Leo, using the James Webb Space Telescope. They found chemical signatures—DMS and DMDS—in its atmosphere, suggesting life beyond Earth.

K2-18b is in its star’s habitable zone and may be a “Hycean world” with a hydrogen-rich atmosphere and an ocean-covered surface.

Descubrimiento en el espacio: galaxia conocida más lejana contiene rastros de oxígeno

(AFP)- La galaxia conocida más lejana contiene trazas de oxígeno, un descubrimiento que refuerza la idea de que estos cúmulos de estrellas que hoy pueblan el cosmos se formaron muy rápidamente en los primeros momentos del universo. Descubierta el año pasado por el telescopio espacial James Webb, la galaxia JADES-GS-z14-0 está tan lejos que su […]

NASA have written this up here: nasa.gov/universe/exoplanets/w

“The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b. These initial #Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life. The bulk of the DMS in Earth’s atmosphere is emitted from phytoplankton in marine environments.”

NASA's Webb Images Young, Giant Exoplanets, Detects Carbon Dioxide
Findings suggest giant exoplanets in HR 8799 system likely formed like Jupiter and Saturn.

The first planet outside our solar system was discovered in the 1990’s, but it wasn’t until more than a decade later astronomers actually obtained a direct image of one. It’s extremely difficult to image an exoplanet, as stars in other planetary systems can be thousands of times brighter and bigger than their planets.

NASA’s James Webb Space Telescope is equipped with a highly sensitive coronagraph, a tiny mask that blocks the light of the star, allowing Webb to image exoplanets.

Webb’s new images of two iconic systems, HR 8799 and 51 Eridani, and their planets have stunned researchers, and provided additional information into the chemical make-up of the young gas giants.

'Utterly cataclysmic': James Webb telescope spots 2 alien planets disintegrating before our eyes

In world-first observations, the James Webb Space Telescope is watching two distant alien planets "spilling their guts into space" as they rapidly disintegrate — and scientists are elated at what they've found.
