A firework at the edge of the Milky Way ✨ Way out on our galaxy’s frontier, a young star is making its grand entrance. Its “birth announcement”? Twin jets of blazing gas, stretching across 8 light-years — twice the distance between our Sun and Alpha Centauri. Captured in infrared by @esawebb, this Herbig-Haro jet (Sh2-284) is ploughing through dust and gas at hundreds of thousands of kilometres per hour. The star powering it weighs around 10 times our Sun and it’s still growing. Such colossal stellar outflows are rare, and their symmetry helps astronomers test theories of how massive stars form. These fireworks are more than just spectacular. They’re clues to how stars were born in the early Universe, in environments poor in heavy elements, much like this pristine corner of our Milky Way. 📸 @NASA, @europeanspaceagency, @canadianspaceagency, @space_telescopes, Y.
