   Explanation: History's first known periodic comet, [5]Comet Halley
   (1P/Halley), returns to the inner Solar System every 76 years or so.
   The famous comet made its last appearance to the naked-eye in 1986. But
   dusty debris from Comet Halley can be seen raining through planet
   Earth's skies twice a year during two annual meteor showers, the [6]Eta
   Aquarids in May and the [7]Orionids in October. In fact, [8]an
   unhurried series of exposures captured these two bright meteors,
   vaporizing bits of Halley dust, during the early morning hours of
   October 23 against a starry background along the Taurus molecular
   cloud. Impacting the atmosphere at about 66 kilometers per second their
   [9]greenish streaks point back to the [10]shower's radiant just north
   of Orion's bright star Betelgeuse off the lower left side of the frame.
   [11]The familiar Pleiades star cluster anchors the dusty celestial
   scene at the right.
