Where it is in space
the nonstellation of Auriga, in our Milky Way Galaxy. It is approx 12,000
light years away from Earth. The star cluster is approx 25 x 25 arc minutes
across (almost the apparent size of the Moon in the sky). In this image,
North is up.

|What it is||
is the gaseous nebula surrounding the bright, hot star cluster of NGC
1893. The radiation from these hot stars pushes the gas away from them
and creates the darker hole like features just above the star cluster.
The "tadpoles" (seen above center) are regions of denser,
cooler gas. These pockets of more dense gas slowly resist the erosive
radiation from the hot stars. The high radiation slowly eats away at
these pockets and the matter streams away from the stars- creating the
tails seen in the image. The tails have grown to 10 light years in length.
