MULTIPLE GENERATIONS OF STARS IN THE TARANTULA
NEBULA
Near the edge of the most active
starburst region in the local universe lies a
cluster of brilliant, massive stars, known to
astronomers as Hodge 301. Hodge 301, seen in the
lower right hand corner of this image, is located
at the edge of the Tarantula Nebula, within one
of our nearest galactic neighbors, the Large Magellanic
Cloud.
This star cluster is not the brightest,
or youngest, or most populous star cluster in
the Tarantula Nebula--that honor goes to the spectacular
R136 at the center of the nebula. In fact, Hodge
301 is almost 10 times older than the young cluster
R136.
But age has its advantages; many
of the stars in Hodge 301 are so old that they
have exploded as supernovae. These stellar explosions
have blasted material out into the surrounding
region at high speeds. As the ejecta plow into
the surrounding Tarantula Nebula, they shock and
compress the gas into a multitude of sheets and
filaments, seen in the upper left portion of the
picture. These features are moving away from Hodge
301 at speeds of more than 200 miles per second.
Note for your calendar; Hodge 301
contains three red supergiants--stars that are
close to the end of their evolution. Over the
next few million years, they will also go supernova,
exploding and sending more shocks into the Tarantula.
Also present near the center of
the image are small, dense gas globules and dust
columns where new stars are being formed today,
as part of the overall ongoing star formation
throughout the Tarantula region.
