Explanation:
Big, beautiful spiral galaxy M101 is one of the last
entries in Charles
Messier's famous catalog, but definitely not
one
of the least.
About 170,000 light-years across, this galaxy is enormous,
almost twice the size of our own Milky Way galaxy.
M101 was also one of the original
spiral
nebulae observed by Lord Rosse's large
19th century
telescope, the Leviathan of Parsontown.
M101 shares this modern telescopic field of view with
spiky foreground stars within the Milky Way, and more
distant background galaxies.
The colors of the Milky Way
stars can also be
found in the starlight from the large island universe.
Its core is dominated by light from cool yellowish stars.
Along
its grand spiral arms are the blue colors of hotter, young stars mixed
with obscuring dust lanes and pinkish star forming regions.
Also known as the
Pinwheel Galaxy,
M101 lies within
the boundaries of the northern constellation Ursa Major,
about 25 million light-years
away.
