Budding stars

The Rosette Nebula (NGC 2237–9) is a vast star-forming complex about 5,000 light-years away in Monoceros. This portrait combines 200⅓ hours of SHO data taken from Jan. 1 to April 12, 2026, with a 5-inch f/5.6 scope. The extremely deep exposure reveals myriad delicate tendrils within the nebula, where where hot young stars are carving a central cavity in hydrogen-rich clouds. At right lies a line of Bok globules — dense nuggets of dust where stars are forming.
