Explanation:
The Milky Way was not created by an evaporating lake.
The colorful pool of water, about 10 meters across, is known as
Silex Spring and is located in
Yellowstone National Park
in
Wyoming,
USA.
Illuminated artificially, the colors are caused by layers of
bacteria
that grow in the
hot spring.
Steam rises off
the spring, heated by a
magma chamber deep underneath known as the
Yellowstone hotspot.
Unrelated and far in the distance, the
central band of our
Milky Way Galaxy arches high overhead, a band lit by billions of stars.
The above picture is a 16-image panorama
taken late last month.
If the Yellowstone hotspot causes another supervolcanic eruption as it did
640,000 years ago, a
large part of North America would be affected.
