Explanation:
What surrounds the Andromeda galaxy?
Out in space, Andromeda (M31) is closely surrounded by several small
satellite galaxies, and further out it is part of the
Local Group of Galaxies -- of which our Milky Way galaxy is also a member.
On the sky, however, gas clouds local to
our Milky Way appear to surround M31 --
not unlike how water clouds in
Earth's atmosphere may appear to
encompass our Moon.
The gas clouds toward Andromeda,
however, are usually too faint to see.
Enter the
featured 45-degree long image
-- one of the deeper images yet taken of the
broader Andromeda region.
This image, sensitive to light specifically
emitted by hydrogen gas, shows these faint and unfamiliar clouds in
tremendous
detail.
But the image captures more.
At the image top is the
Triangulum galaxy (M33),
the third largest galaxy in the
Local Group and the furthest object that can be seen with the unaided eye.
Below M33 is the bright Milky-Way star
Mirach.
The image is the digital accumulation of
several long exposures taken from 2018 to 2021 from
Pulsnitz,
Germany.
