ViewSpace Interactives: Dark Matter

Scientists know more about what dark matter isn’t than what it is. We know dark matter exists because of its gravitational effects on objects we do see – objects that emit or reflect light. When space is warped by dark matter’s gravity, the light of distant galaxies and bright objects within them, like supernovas, appear distorted. Astronomers calculate that there is much more dark matter in the universe than matter we can currently see. Explore what we know about dark matter by clicking through a progression of images featuring Supernova Refsdal and the Bullet Cluster.
