Explanation:
Shiny NGC 253
is one of the brightest spiral galaxies visible, and also one of
the dustiest.
Some call it the Silver Dollar Galaxy for its appearance in small
telescopes, or just the Sculptor Galaxy for its location within
the boundaries of the southern constellation Sculptor.
Discovered in 1783 by mathematician and astronomer
Caroline Herschel,
the dusty island universe lies a mere 10 million light-years away.
About 70 thousand light-years across, NGC 253 is the largest member of
the Sculptor
Group of Galaxies, the nearest to our own
Local Group of
Galaxies.
In addition to its spiral dust lanes, tendrils of dust seem to be
rising from a galactic disk
laced with young star clusters and star forming regions in this
sharp color image.
The high dust content accompanies frantic star formation,
earning
NGC 253 the designation of a
starburst
galaxy.
NGC 253 is also known to be a strong
source
of high-energy x-rays and gamma rays, likely due to massive
black holes near the galaxy's center.
