Explanation:
How well do you know the night sky?
OK, but how well can you identify famous sky objects in a
very deep image?
Either way, here is a test: see if you can find some well-known
night-sky icons
in a deep image filled with faint nebulosity.
This image contains the
Pleiades star cluster,
Barnard's Loop,
Horsehead Nebula,
Orion Nebula,
Rosette Nebula,
Cone Nebula,
Rigel,
Jellyfish Nebula,
Monkey Head Nebula,
Flaming Star Nebula,
Tadpole Nebula,
Aldebaran,
Simeis 147,
Seagull Nebula and the
California Nebula.
To find their real locations,
here is an annotated image version.
The reason this task might be difficult is similar to the reason it is initially
hard to identify familiar
constellations
in a very
dark sky:
the tapestry of our night sky has an extremely deep
hidden complexity.
The
featured composite
reveals some of
this complexity in a
mosaic of 28 images taken over 800 hours from dark skies over
Arizona,
USA.
