A smile written in starlight ✨ For World Smile Day (3 October), here’s a reminder that the Universe has its own way of beaming back at us. This glittering scene shows Pismis 24, a young star cluster at the heart of the Lobster Nebula, 5500 light-years away in Scorpius. What looks like a rugged, glowing landscape is in fact a cosmic dust-scape being carved apart by fierce winds and radiation from massive, newborn stars. Among them is Pismis 24-1 — once thought to be the most massive star ever seen, and now known to be at least two enormous stars bound together. Captured by @esawebb, thousands of jewel-like stars sparkle across the view, with towering orange spires and wisps of gas sculpted into fantastic shapes by stellar energy. A cosmic smile — reminding us that even in the vastness of space, light and joy can take shape. 📸 @NASA, @europeanspaceagency, @canadianspaceagency, @space_telescopes; @creativecommons CC BY 4.0 📹 NASA, ESA, CSA, STScI, N.
