Explanation:
Few astronomical sights excite the imagination like the
nearby stellar nursery known as the Orion Nebula.
The Nebula's glowing gas
surrounds hot young stars at the edge of an immense interstellar
molecular cloud.
Many of the filamentary structures visible in the featured image are actually
shock waves -
fronts where fast moving material encounters slow moving gas.
The Orion Nebula spans about 40
light years
and is located about 1500 light years away in the
same spiral arm
of our Galaxy as the
Sun.
The Great Nebula in
Orion can be found with the
unaided eye just below and to the left of the easily identifiable
belt of three stars in the popular constellation Orion.
The image shows the nebula in
three
colors
specifically emitted by
hydrogen,
oxygen, and
sulfur gas.
The whole Orion Nebula cloud complex,
which includes the
Horsehead Nebula,
will slowly disperse over the next 100,000 years.
