Explanation:
What are these two giant arches across the sky?
Perhaps the more familiar one, on the left, is the central band of our
Milky Way Galaxy.
This grand disk of stars and nebulas here appears to encircle much of the southern
sky.
Visible below the stellar arch is the
rusty-orange planet
Mars and the extended
Andromeda galaxy.
But this night had more!
For a few minutes during this
cold
arctic night, a second
giant arch appeared
encircling part of the northern sky: an
aurora.
Auroras are much closer than stars as they are composed of glowing air high in
Earth's atmosphere.
Visible outside the
green auroral arch is the group of stars popularly
known as the
Big Dipper.
The featured digital composite of 20 images was captured in
mid-November 2022 over the
Lofoten Islands in
Norway.
