The Rosette Nebula (NGC 2237) is a vast emission nebula located approximately 5,200 light-years away in the constellation Monoceros. This stellar nursery spans over 130 light-years and is home to the young, energetic open cluster NGC 2244, whose intense radiation carves out the nebula’s intricate structure.

Captured from a Bortle 4 site in Myślenice, Poland, this image was processed in the Hubble Palette (SHO), where ionized sulfur (SII) appears red, hydrogen-alpha (Hα) green, and ionized oxygen (OIII) blue. This mapping enhances the nebula’s complex filaments and shock fronts sculpted by stellar winds and radiation pressure. The image reveals the nebula’s inner cavities, formed by the relentless forces of young, massive stars, offering a glimpse into the dynamic processes driving star formation in this iconic deep-sky region.
