Explanation:
What's happening above that volcano?
Although Mount Etna is seen
erupting, the clouds are not related to the
eruption.
They are lenticular clouds
formed when moist air is forced upwards near a mountain or
volcano.
The surreal scene was captured by chance
late last month when the astrophotographer went to Mount Etna, a
UNESCO
World Heritage Site in
Sicily,
Italy,
to photograph the conjunction between the Moon and the star
Aldebaran.
The Moon appears in a bright
crescent phase,
illuminating an edge of the lower lenticular cloud.
Red hot lava flows on the right.
Besides some breathtaking stills, a companion
time-lapse video of the scene
shows the
lenticular clouds
forming and wavering as
stars trail far in the distance.
