Galaxy M 94

M 94 is a small, active spiral galaxy. The speed of rotation of the stars around the galactic center of M 94 strongly decreases, when going further outside. This leads to the conclusion, that dark matter is lacking here nearly completely. Dark matter is what allows most other galaxies a faster rotation.
