   Explanation: History's first known periodic comet Halley (1P/Halley)
   returns to the inner Solar System every 75 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 Eta Aquarids
   in May and the Orionids in October. Including meteors near the shower
   maximum on October 21, this composite view compiles Orionid meteors
   captured from years 2015 through 2022. About 47 bright meteors are
   registered in the panoramic night skyscape. Against a starry background
   extending along the Milky Way, the Orionid meteors all seem to radiate
   from a point just north of Betelgeuse in the familiar constellation of
   the Hunter. In the foreground are mountains in eastern Slovakia near
   the city of Presov.
