Explanation:
Have you ever seen the band of our
Milky Way Galaxy?
Chances are you have never seen it like this --
nor could you.
In a clear sky from a dark location at the right time, a
faint band of light is visible across the sky.
This band is the disk of our
spiral galaxy.
Since we are inside this disk, the band appears to encircle the Earth.
The above spectacular picture of the Milky Way arch, however, goes where the unaided eye cannot.
The image is actually a deep digital fusion of nine photos that create a panorama
fully 360 across.
Taken recently in
Teide National Park in
Tenerife,
Canary Islands,
Spain, the image includes the
Teide volcano, visible near the image center, behind a volcanic landscape that
includes many large rocks.
Far behind these Earthly structures are many sky wonders
that are visible to the unaided eye, such as the band of the Milky Way, the bright
waxing Moon
inside the
arch, and the
Pleiades open
star cluster
(can you find it?).
The deep exposure also brings out many sky wonders normally beyond
human perception, many of which are labelled on the annotated image version,
including
Barnard's Loop,
visible above as the half red ring below the
Milky Way band.
