Explanation:
Few cosmic vistas excite the imagination like
the Orion Nebula.
Also known as
M42,
the nebula's glowing gas surrounds hot young stars at the edge of an
immense interstellar molecular cloud only 1,500 light-years away.
The Orion Nebula offers one of the best opportunities
to study how stars are born partly because it is the nearest large
star-forming region, but also because the nebula's
energetic stars have
blown away
obscuring gas and dust clouds that
would otherwise block
our view - providing an intimate look at a
range of ongoing stages
of
starbirth and evolution.
This detailed image of the
Orion Nebula is the sharpest ever, constructed using data from
the Hubble Space Telescope's Advanced Camera for Surveys
and the European Southern Observatory's
La Silla 2.2 meter telescope.
The mosaic
contains a billion pixels at full resolution
and reveals about 3,000 stars.
In apparent size, the picture is as large as the Full Moon.
At the distance of M42 it spans thirteen light-years.
