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.
