Explanation:
There is something very unusual in this picture of the Earth -- can you find it?
A fleeting phenomenon once thought to be only a legend has been newly caught if you
know just where to look.
The featured
image
was taken from the orbiting
International Space Station (ISS)
in late April and shows familiar
ISS solar panels on the far left and part of a robotic
arm to the far right.
The rarely imaged phenomenon is known as a
red sprite and it
can
be seen,
albeit faintly, just over the bright area on the image right.
This bright area and the red sprite
are different types of lightning,
with the white flash the more typical type.
Although sprites have been reported
anecdotally for as long as 300 years, they were first caught on film in 1989
-- by accident.
Much remains unknown about
sprites including how they occur, their effect on the
atmospheric
global
electric circuit,
and if they are somehow related to other
upper atmospheric
lightning
phenomena such as
blue jets or
terrestrial gamma
flashes.
