Wat versta jij onder bio signatuur?

Ik pas in deze. Die laat ik over aan NASA en trawanten.

Spectrofotometrische waardes van organische stoffen?

Ja, maar daar zit ook een grijs gebied in, zoals ik laatst ook gepost heb over cyanide.

For the first time astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A).

An international team of astronomers has used NASA’s James Webb Space Telescope to provide the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than previously thought.

This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds. HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.

The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*.

James Webb Space Telescope discovers oldest and most distant black hole ever seen

The ravenous black hole that existed just 400 million years after the Big Bang could help explain how supermassive black holes grew so rapidly.

Through Webb’s infrared eye, NGC 604 has revealed envelopes of dusty gas that astronomers believe to be among the hottest and most massive stars of their kind, all of which are veritable infants in their stellar nursery. Comprised mostly of what are known as B-type and O-type stars, some of these are more than 100 times the mass of Earth’s host star.

James Webb Space Telescope Discovery Reveals a Dark Matter Anomaly Related to Ghostly 'Einstein Ring' - The Debrief

A remnant of the early universe discovered last year by the Webb Telescope has yielded a few surprises, including an Einstein ring.
