Tour de force: Western Space researchers chart Orion Nebula like never before
Tour de force: Western Space researchers chart Orion Nebula like never before
Els Peeters, Jan Cami and collaborators among first scientists to use James Webb telescope for research and they targeted star formation Star and planet formation is a messy affair. It starts with the gravitational collapse of a gigantic cloud of gas and dust, which simultaneously produces massive stars, whose intense radiation field creates a harsh environment, as well as more modest stars, like our Sun, surrounded by a planet-forming disk that is rich in organic materials.

Velvet Worm slime could inspire sustainable synthetic materials
Fibers produced from the slime exhibit a strength akin to nylon, yet they can dissolve in water and be reconstituted into new fibers from the solution In the tropical, temperate forests it calls home, the velvet worm uses a projectile "slime" to capture its prey. When it's ejected from the worm, the slime transforms into a gel before solidifying into stiff fibers upon exposure to air.
