Spindle Galaxy 소개

설명

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.

관측 팁

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.

역사

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.

재미있는 사실

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.
