M78: Stardust and Starlight
Explanation:
Interstellar
dust clouds and bright nebulae abound in the fertile
constellation of Orion
. One of the
brightest, M78
, is just below center in this
sharp widefield 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 that
also includes
the remarkable
McNeil's Nebula
-- a newly recognized nebula
associated with
the formation of a sun-like star.
