Columba, the Dove, is a minor constellation just south of Lepus (the Hare). This picture shows slightly slant because taken when the constellation was going down to the west sky, the whole figure of Columba looks like "T" shape in culmination. Columba shows the bird with flapping wings and holding a sprig of olive in its mouth. The constellation first appeared in 17th century, and may refer to the dove in the story of Noah and the Ark.
According to the investigation for the motion of stars close to the solar system, almost all of them seem to move forward to around the northern region in Columba. It's considered that the region agrees with the opposite point of the solar apex in Hercules. The sun and its all family are moving to the apex with the velocity about 19 km/s (12 miles/s) in the Galaxy.
