NGC 4526 is a lenticular galaxy in the Virgo constellation. In a telescope, it looks like a lentil-shaped structure with spiral arms. It is one of the brightest lenticular galaxies.[3] It is thought that a supermassive black hole is in the center of the galaxy. Astronomers say that the supermassive black hole is 450 million times the mass of the Sun.[4]
Since astronomers found this galaxy, two supernovas have occurred around it. The most recent was SN 1994D, which was the supernova of a white dwarf that was made of carbon and oxygen. NGC 4526 spins at a speed of 250 kilometers per second (559,234 mph or about 900,000 kph).[5]
