Explanation:
Far beyond
the local
group of galaxies lies
NGC 3621,
some 22 million light-years away.
Found in the multi-headed southern constellation
Hydra,
the winding spiral arms of this gorgeous
island universe are loaded with
luminous blue star clusters, pinkish starforming regions,
and dark dust lanes.
Still, for astronomers
NGC 3621
has not been just another
pretty face-on spiral galaxy.
Some of its brighter stars have been used as
standard candles to establish important estimates of extragalactic
distances
and the
scale
of the Universe.
This beautiful image of NGC 3621,
is a composite of space- and ground-based telescope
data.
It traces the loose spiral arms far from the galaxy's brighter
central regions for some 100,000 light-years.
Spiky foreground stars in our own Milky Way Galaxy and
even more distant background galaxies are scattered across
the colorful skyscape.
