Explanation:
NGC 1333 is seen in visible light as
a reflection nebula,
dominated by bluish hues characteristic of starlight reflected by
interstellar dust.
A mere 1,000 light-years distant toward the heroic constellation
Perseus,
it lies at the edge of a large,
star-forming molecular cloud.
This striking close-up spans
about two full moons on the sky or just over
15 light-years at the estimated distance of NGC 1333.
It shows details
of the dusty region along with hints of contrasting red emission from
Herbig-Haro
objects, jets
and shocked glowing gas emanating from recently formed stars.
In fact, NGC 1333 contains hundreds of stars less than
a million years old, most still
hidden
from optical telescopes by the
pervasive stardust.
The chaotic environment may be similar to one in which our own Sun
formed over 4.5 billion years ago.
