It is visible at latitude between 45 degrees and -90 degrees. It is a small constellation, covering an area of 270 square degrees.

There is no mythology associated with Columba. It is one of 12 fairly recent constellations named by the Dutch astronomer Petrus Plancius based on observations by Dutch navigators. Plancius included it on his celestial globe in 1592. Plancius originally named the constellation Columba Noachi, which means Noah’s dove. It refers to the dove that brought an olive branch to Noah to show that the Great Flood was receding. In some other interpretations, the dove represents the bird the Argonauts sent out ahead to help them navigate the narrow passage at the mouth of the Black Sea. The German astronomer Johann Bayer included this constellation in his star atlas in 1603 and the name was eventually shortened to Columba.
