M100 - Galaxy in Coma Berenices

M100 is a spiral galaxy, like our Milky Way, and tilted nearly face-on
as seen from earth. It is estimated to be 60 million light years
distant with a diameter of about 160,000 light years, and with a total
mass of about 160 billion suns. The galaxy has two prominent arms of
young, hot bright blue stars and several fainter arms. The galactic
shape has been modified by nearby companions.
