Seven Sisters versus California
Explanation: On the upper right, dressed in blue, is the
Pleiades. Also known as the
Seven Sisters and
M45,
the Pleiades is one of the brightest and
most easily visible open clusters on the sky.
The Pleiades contains over 3,000 stars, is about 400 light years away, and only 13 light years across.
Surrounding the stars is a spectacular blue
reflection nebula made of fine
dust.
A common legend is that one of the brighter stars faded since the cluster was named. On the lower left, shining in red, is the
California Nebula. Named for its shape, the
California Nebula is much dimmer and hence harder to see than
the Pleiades. Also known as
NGC 1499, this mass of red glowing hydrogen gas is about 1,500
light years away. Although about 25 full moons could fit
between them, the
featured wide angle, deep field image composite has captured
them both. A
careful inspection of the deep image will also reveal the star forming region
IC 348 and the
molecular cloud LBN 777 (the Baby Eagle Nebula).
