Hodge 301
Hodge 301 Hodge 301 is a star cluster in the Tarantula Nebula,
visible from Earth’s Southern Hemisphere. The cluster
and nebula lie about 168,000 light years away, in one of
our Milky Way Galaxy’s orbiting satellite galaxies, the
Large Magellanic Cloud.
Hodge 301, along with the cluster R136, is one of two
major star clusters situated in the Tarantula Nebula, a
region which has seen intense bursts of star formation
over the last few tens of millions of years. R136 is situated
in the central regions of the nebula, while Hodge 301 is
located about 150 light years away, to the north west
as seen from Earth. Hodge 301 was formed early on in
the current wave of star formation, with an age estimat-
ed at 20-25 million years old, some ten times older than
R136.[2]
Since Hodge 301 formed, it is estimated that at least

tion around R136, which is young enough that none of its
Constellation Dorado stars have yet exploded as supernovae; instead, the stars

ing with the surrounding gases. The two clusters thus
