Explanation:
The odd looking "creature" to the
right of center in the above photo is a gas cloud known as a cometary globule.
This globule, however, has ruptured. Cometary globules
are typically characterized by dusty
heads and elongated tails. These features cause cometary globules
to have visual similarities to comets,
but in reality they are very much different. Cometary globules
are frequently the birthplaces of stars,
and many show very young stars in their heads. The reason for
the rupture in the head of this object is not completely known.
The galaxy to the left of center
is very far in the distance and is only placed near CG4 by chance
superposition.
