An astronomer observes the Orionids at an observatory near the village of Avren east of the Bulgarian capital Sofia. The Orionid meteor shower occurs each year as a result of Earth passing through cosmic dust released by Halley's Comet. The radiant of the Orionids is located near the constellation Orion.
