Explanation:
This telescopic close-up shows off the central regions of
otherwise faint emission nebula IC 410, captured under backyard
suburban skies with
narrowband filters.
It also features two remarkable inhabitants of the cosmic pond of gas
and dust.
Below and right of center are the tadpoles of IC 410.
Partly obscured by foreground dust, the nebula itself
surrounds NGC 1893, a young
galactic cluster of stars.
Formed in the interstellar cloud a mere 4 million years ago, the
intensely hot, bright
cluster stars energize the glowing gas.
Composed of denser cooler gas and dust,
the tadpoles are around 10 light-years long and are
likely sites of ongoing
star
formation.
Sculpted by stellar winds and radiation their heads are outlined by
bright
ridges of ionized gas
while their tails trail away from the cluster's central young stars.
IC 410 lies some 10,000 light-years away,
toward the nebula-rich constellation Auriga.
