Explanation:
Stars are sometimes born in the midst of chaos.
About 3 million years ago in the nearby galaxy
M33, a large cloud of gas
spawned dense internal knots which gravitationally
collapsed to form stars.
NGC 604 was so large, however, it could form enough stars to make a
globular cluster.
Many young stars from
this cloud are visible in the
above image from the
Hubble Space Telescope,
along with what is left of the initial
gas cloud.
Some stars were so massive they have already
evolved and exploded in a
supernova.
The brightest stars that are left emit light
so energetic that they create one of the largest clouds of
ionized hydrogen gas known,
comparable to the
Tarantula Nebula in our
Milky Way's close neighbor, the
Large Magellanic Cloud.
