Description

This galaxy is called a grand-design spiral, with long, large and clearly defined spiral arms — giving it a structure somewhat similar to our home galaxy, the Milky Way.

M99 was discovered by the French astronomer Pierre Méchain in 1781. The galaxy is located 55 million light-years from Earth in the constellation Coma Berenices and has an apparent magnitude of 10.4. It can be seen using a moderately sized telescope most easily in May.
