M100 Spiral Galaxy

M100 Spiral Galaxy

Object: M100
Constellation: Coma Berenices
Distance: 56 Million Light-Years
Magnitude: 9.3
Comments: M100 is a grand design spiral galaxy seen face-on. It is one of the brightest members of the Virgo Group, and has two prominent bright arms with young, hot blue stars, and several fainter arms. Its slightly asymetric shap is probably caused by interaction with another nearby galaxy. Four supernovae have thus far been discovered in M100. For a more detailed description of M100, see Rob Gendler's essay HERE
