Falling into the web! 🕸️ Fly to the Orion Nebula, located 1350 light-years away and the nearest region of massive star formation to Earth. But what are those wispy, web-like structures seen in the final image?  🔭 1/2

Webb unveils young stars across every stage of formation in this spectacular view from the Orion Molecular Clouds. Explore the image to spot: 🛜 shockwaves from hidden protostars 🥏 protoplanetary discs and 🌟 large, bright stars 🔭 🧪 1/2

An area inside a star-forming molecular cloud. The background is covered with layers of gas and dust in blue, green and yellowish colours. Thicker clumps of cold dust, dark brown to black, block out light completely. Stars lie among and atop the clouds, from small orange ones to large white or blue ones. Waves and streams of glowing whitish gas are created by jets from protostars colliding with the surrounding material. Credit: ESA/Webb, NASA & CSA, T. Megeath, M.

Ein internationales Team unter Beteiligung von Sylvia Ploeckinger von der Universität Wien entwickelte mit COLIBRE eine neue Sammlung kosmologischer Simulationen: Die virtuellen Universen bieten das bisher realistischste Bild der Galaxienentstehung und -entwicklung seit nahezu Anbeginn der Zeit. ⤵️🔭🌌

Die kalte und staubige Seite der Galaxienentstehung

Neue Simulationen bestätigen kosmologisches Standardmodell – COLIBRE macht Galaxien-Entwicklung auch hörbar
