Explanation:
Yes, but have you ever seen aurora from a cave?
To capture
this fascinating juxtaposition
between below and above, astrophotographer Bjargmundsson
spent much of a night alone in the kilometer-long
RaufarhСlshellir
lava cave in Iceland during late
March.
There, he took separate images of three parts of
the cave
using a strobe for illumination.
He also took a deep image of the sky to capture
faint aurora,
and digitally combined the four images later.
The 4600-year old lava tube
has several skylights under which stone rubble and snow have accumulated.
Oh -- the person standing on each mound -- it's
the artist.
