Explanation:
Can you find the Rosette Nebula?
The large, red,
and flowery-looking nebula on the upper left
may seem the obvious choice, but that is actually just diffuse
hydrogen emission surrounding the
Cone and Fox Fur Nebulas.
The famous Rosette Nebula is really located on the lower
right and connected to the
other nebulas by irregular filaments.
Because the
featured image of Rosetta's field is so
wide and deep,
it seems to contain other flowers.
Designated NGC 2237, the center of the Rosette nebula
is populated by the bright blue stars of open cluster
NGC 2244,
whose winds and
energetic light are evacuating the nebula's center.
The Rosette Nebula is about 5,000 light years distant and, just by itself,
spans about three times the diameter of a
full moon.
This flowery field can be found toward the
constellation of the
Unicorn
(Monoceros).
