Explanation:
Sometimes both heaven and Earth erupt.
Colorful aurorae erupted unexpectedly a few years ago, with
green aurora appearing near the horizon and brilliant
bands of
red aurora blooming high overhead.
A bright Moon lit the foreground of this picturesque scene,
while familiar stars could be seen far in the distance.
With planning, the careful astrophotographer shot this image mosaic in the field
of
White Dome Geyser in
Yellowstone National
Park
in the western USA.
Sure enough, just after midnight,
White Dome erupted -- spraying a stream of water and vapor many meters into
the air.
Geyser water is heated to steam
by
scalding magma several
kilometers below, and rises through rock
cracks to the surface.
About half of all known geysers occur in
Yellowstone National Park.
Although the
geomagnetic
storm
that created these aurorae has since subsided, eruptions of White Dome Geyser continue
about every 30 minutes.
