NGC 524
NGC 524 is a lenticular galaxy in the constellation Pisces. It is at a distance of about 90 million light-years away from Earth. In the central bulge of the galaxy is visible gas forming a spiral structure.[2] It is the largest galaxy in a small galaxy group, the NGC 524 group, which is associated with NGC 488 and its group.[3] It was discovered by William Herschel in 1786. Two supernovae have been observed in the galaxy, SN 2000cx, a type Ia-p peaking at 14.5 magnitude, and SN 2008Q, type Ia.[4]
