Sobre Rosette Nebula
Descrição
The Rosette Nebula (NGC 2237) is a large, circular emission nebula in Monoceros, about 5,200 light-years away. It spans 1.3 degrees (over 2 full Moons) and surrounds the open cluster NGC 2244 (C50), whose hot young stars ionize the hydrogen gas and create the rose-shaped glow.
Dicas de Observação
Due to its large size, best in binoculars or a wide-field telescope at very low power. An OIII or UHC filter is almost essential to see the nebulosity visually. The embedded cluster C50 is easy without a filter. Best in winter evenings.
História
The nebula was discovered in different parts by John Herschel and others in the 1830s. Lewis Swift observed additional sections. The full rosette shape was only appreciated through photography.
Curiosidades
The Rosette Nebula contains enough gas to form about 10,000 solar-mass stars. The central hole is being carved out by the stellar winds and radiation from the hot OB stars in cluster C50. Eventually the gas will be completely dispersed.
