Swirls and Stars in IC 4678
Explanation:
Swirls of gas and dust enrich this little observed
starfield
toward the
constellation
of
Sagittarius
.
Just to the
side
of the
more often photographed
Lagoon Nebula
(
M8
)
and the
Trifid Nebula
(
M20
)
lies this busy patch of sky dubbed IC 4678.
Prominent in the
above image
are large
emission nebulas
of red glowing gas highlighted by
unusually bright red filaments.
On the left, a band of thin
dust
preferentially reflects the blue light of a bright star
creating a small
reflection nebula
.
On the right and across the bottom, swaths of
thicker dust
appear as
dark absorption nebulas, blocking the light from stars
farther in the distance.
IC 4678 spans about 25
light years
and lies about 5,000 light years distant.
