Flying through the star cluster Messier 67

This artist's impression takes the viewer on a trip through the old star cluster Messier 67 in the constellation of Cancer (The Crab). Observations using ESO's HARPS instrument on the 3.6-metre telescope at La Silla in Chile, along with other telescopes, have found three planets orbiting stars in this cluster. An artists's impression of one of these planets can be seen at the end of this video.
