Perseids Around the Milky Way
Explanation: Why would meteor trails appear curved? The arcing effect arises only because the image
artificially compresses (nearly) the whole sky
into a rectangle. The meteors are from the
Perseid Meteor Shower that peaked last week. The featured multi-frame image combines not only different directions from the 360 projection, but different times when
bright Perseid meteors momentarily streaked across the sky. All
Perseid meteors can be traced back to the
constellation Perseus toward the lower left, even the seemingly curved (but really straight)
meteor trails. Although Perseids always point back to their
Perseus radiant, they can appear almost anywhere on the sky. The image was taken from
Inner Mongolia,
China, where
grasslands meet
sand dunes. Many treasures also visible in the busy night sky including the
central arch of our
Milky Way Galaxy, the planets
Saturn and Jupiter toward the right,
colorful airglow on the central left, and some relatively nearby Earthly clouds. The Perseid
Meteor Shower peaks every August.
