NGC 1309 and Friends


Explanation:

A gorgeous
spiral galaxy some 100 million light-years distant,
NGC
1309
lies on the banks of the constellation
Eridanus.

NGC 1309 spans about 30,000 light-years, one third the size
of our larger Milky Way galaxy.

Bluish clusters of young stars and
dust lanes are seen to trace out
NGC 1309's spiral arms as they wind around an older yellowish star
population at its core.

Not just another pretty face-on spiral
galaxy, observations of
NGC 1309's recent supernova and cepheid stars contribute to the
calibration of
the expansion of the Universe.

Still, after you get over this beautiful galaxy's
grand design,
check out
the array of more distant background galaxies also recorded
in the sharp Hubble Space Telescope view.
