Explanation:
Interstellar
dust clouds and bright nebulae abound in the fertile
constellation of Orion.
One of the
brightest,
M78, is just left of center in
this colorful
telescopic view, covering an area north of
Orion's belt.
At a distance of about 1,500 light-years, the
bluish nebula itself
is about 5 light-years across.
Its blue tint is due to dust
preferentially
reflecting the blue light
of hot, young stars in the region.
Dark dust lanes and other nebulae can easily be traced
through this gorgeous skyscape.
The scene
also
includes the remarkable
McNeil's Nebula -- a newly
recognized nebula
associated with
the formation of a sun-like star, and the telltale reddish glow of many
Herbig-
Haro objects, energetic jets from stars in the process
of formation.
