TOPSHOTS A long exposure image showing an aeroplane passing in the sky during the Perseids meteor shower over the remains of St. Ilia Roman early Christian basilica dated back to the 5th-6th century AD near the town of Pirdop, early on August 12, 2015. The Perseid meteor shower occurs every year in August when the Earth passes through the debris and dust of the Swift-Tuttle comet. The Perseid meteor shower -- an annual display of natural fireworks -- should be particularly spectacular this year, with extra-dark skies expected to create optimal stargazing conditions, astronomers said on August 7, 2015.
