Messier 108 is also known as NGC 3556 and nicknamed the Surfboard Galaxy. It is a barred spiral galaxy about 46 million light-years away from Earth. It resides in the northern constellation Ursa Major. It is called the Surfboard galaxy because when viewed with a telescope, it is seen nearly edge-on. There is no apparent bulge or pronounced core.
