This cosmic expanse of dust, gas, and stars covers close to 3 degrees
on the sky in the heroic constellation
Right of center in the
is the dusty blue reflection nebula
about 1,000 light-years away.
At that estimated distance, the field
of view is about 50 light-years across.
Next to NGC 1333 is the reddish glow of shocked hydrogen gas created
by energetic jets and winds from stars in the process of formation.
Other reflection nebulae are scattered around,
along with remarkable
dark dust nebulae.
Near the edge of a large
they tend to hide the newly
formed stars and young stellar objects
or protostars from prying optical telescopes.
Collapsing due to
form around dense cores embedded in the molecular cloud.
