The James Webb Space Telescope is helping to bring clarity to star formation process—literally. ✨ Dense clouds of gas and dust tend to envelop regions where forming and young stars reside. Before Webb was in operation, astronomers were limited in the amount of detail they could gather about the star formation process. This included not being able to define the lower threshold, the least amount of mass an object can have while still forming like a star. Scientists have been able to roughly determ

Early Universe, Star Formation Lynx arc, super-cluster that contains a million blue-white stars twice as hot as similar stars in our Milky Way galaxy. The Lynx arc is one million times brighter than the well-known Orion Nebula, a nearby prototypical 'starbirth' region visible with small telescopes. The stars in the Lynx arc are more than twice as hot as the Orion Nebula's central stars, with sun face temperatures up to 80 000°C. Though there are much bigger and brighter star-forming regions than
