Sobre Spindle Galaxy
Descrição
The Spindle Galaxy (NGC 3115) is a lenticular galaxy in Sextans, about 32 million light-years away. Seen edge-on, it has a prominent central bulge that tapers to a thin, lens-shaped disk, giving it its spindle shape.
Dicas de Observação
One of the brighter lenticular galaxies, visible in a 4-inch telescope as a bright, elongated smudge with a concentrated center. An 8-inch scope shows the spindle shape clearly. Best in spring evenings.
História
Discovered by William Herschel on February 22, 1787. Modern observations have detected a supermassive black hole of about 1 billion solar masses at its center — one of the nearest billion-solar-mass black holes to Earth.
Curiosidades
NGC 3115 holds the record for the nearest galaxy with a definitively measured billion-solar-mass black hole. Despite being a lenticular galaxy with little gas, faint dust rings suggest it may have accreted a small companion in the past.
