Explanation:
Denizens of planet Earth typically watch meteor showers
by looking up.
But this
remarkable view,
captured on August 13, 2011 by astronaut Ron Garan,
caught a Perseid meteor by looking down.
From Garan's perspective on board the
International Space Station
orbiting at an altitude of about 380 kilometers,
the Perseid meteors streak below,
swept up dust from
comet Swift-Tuttle.
The
vaporizing
comet dust
grains are traveling at about 60 kilometers per second through
the denser atmosphere around 100 kilometers above Earth's surface.
In this case, the foreshortened meteor flash is near frame center,
below the curving limb of the Earth and a layer of greenish
airglow, just below bright star Arcturus.
Want to look up at a meteor shower?
You're
in luck,
as the 2024 Perseid meteor shower
is active now and predicted to peak near August 12.
With interfering bright moonlight absent, this year you'll likely
see many Perseid meteors under clear, dark skies after midnight.
