Sobre C48
Descrição
NGC 2775 is a spiral galaxy in Cancer, about 55 million light-years away. It has an unusually smooth, bright central region surrounded by tightly wound, faint spiral arms with a distinctive flocculent (patchy) structure.
Dicas de Observação
Visible as a moderately bright, round glow with a prominent nucleus in a 6-inch telescope. Not much spiral structure is visible visually. Best in winter and spring evenings.
História
Discovered by William Herschel on March 19, 1783. Hubble Space Telescope images revealed that the spiral arms contain almost no gas, suggesting star formation has nearly ceased.
Curiosidades
NGC 2775 has an unusually large and bright bulge relative to its disk, and its spiral arms are remarkably gas-poor. It appears to be a galaxy that has exhausted most of its raw material for making new stars.
