Galactic Center Star Clusters


If you had
, the central regions
of our Galaxy would not be hidden from
view by cosmic dust clouds.

the Milky Way
toward Sagittarius might look something
like this.

Pleasing to look at, the gorgeous false-color representation of
x-ray data
from the Chandra Observatory shows
high energies in blue, medium in green,
and low energy x-rays in red.

mosaic spans
about 130 light-years at the 26,000 light-year
distance of the Galactic Center.

It reveals massive, x-ray emitting star clusters
in a crowded environment.

In particular,
the Galactic Center cluster and the enormous
black hole
Sagittarius A* are within the bright region near the

Two other star clusters, the Arches,
and the Quintuplet
lie near the top.

Cluster interactions with dense molecular clouds in the region
may produce some of the diffuse emission detected in
the Chandra
x-ray view.
