NGC 3115: The Spindle Galaxy with a Supermassive Black Hole

Within the constellation Sextans, the Spindle Galaxy, or NGC 3115, is observed edge-on from Earth, displaying a lens-like appearance. Discovered by William Herschel in 1787, it is a lenticular galaxy with a central bulge housing a supermassive black hole.
