Here is another great image from NASA's Jet Propulsion Laboratory:
The double cluster NGC 1850 lies in a neighboring satellite galaxy,
the Large Magellanic Cloud. It has two relatively young components. The
main, globular-like cluster is in the center. A smaller cluster is
seen below and to the right, composed of extremely hot, blue stars and
fainter red T-Tauri stars. The main cluster is about 50 million years
old; the smaller one is 4 million years old.
A filigree pattern
of diffuse gas surrounds NGC 1850. Scientists believe the pattern formed
millions of years ago when massive stars in the main cluster exploded
as supernovas.
