NASA’s Webb Redefines Dividing Line Between Planets, Stars

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

A #chemical ‘Goldilocks zone’ may limit which #planets can host #life
Research highlights a narrow chemical balance needed to preserve key nutrients
Elements such as #phosphorus and #nitrogen are crucial to assembling cell walls, encoding genetic information and building proteins, among other roles. Imagining life without these nutrients is a stretch, Walton says. “It’s really hard to come up with what an alternative biology would look like.”

A chemical ‘Goldilocks zone’ may limit which planets can host life

Life needs nutrients like nitrogen and phosphorus. But without the right balance of oxygen, these elements get locked away in planets’ cores.

Zwischen ewiger Nacht und ewigem Tag: Klimakarten zweier Erdverwandter

Mit Hilfe des James-Webb-Weltraumteleskops JWST ist es einem internationalen Team mit Beteiligung der Universität Bern, der Universität Genf sowie des Nationalen Forschungsschwerpunkts (NFS) PlanetS gelungen, detaillierte Klimakarten von zwei felsigen Exoplaneten mit erdähnlicher Masse zu erstellen. Die Messungen offenbaren ein Extremklima: Auf den Tagseiten steigen die Temperaturen auf weit über 100 Grad Celsius, während die Nachtseiten in Kälte unter –200 Grad Celsius erstarren. Diese ausgeprägten Gegensätze sprechen dafür, dass die Planeten keine dichten Atmosphären besitzen. Die beiden untersuchten Planeten gehören zum legendären Planetensystem TRAPPIST-1, das als wahres Labor für die Erforschung von extrasolaren Welten gilt.
