Explanation:
Sprawling emission nebulae IC 1396 and Sh2-129 mix
glowing interstellar gas and dark dust clouds in this nearly
12 degree wide field
of view toward the northern constellation
Cepheus
the King.
Energized by its central star
IC 1396 (left),
is hundreds of light-years across and some 3,000 light-years distant.
The nebula's intriguing dark shapes include
a winding dark cloud popularly known as the
Elephant's Trunk below and right of center.
Tens of light-years long, it holds the
raw material for star formation and is known to hide
protostars
within.
Located a similar distance from planet Earth, the
bright knots and swept back ridges of emission of Sh2-129 on the right
suggest its popular name, the
Flying Bat Nebula.
Within the Flying Bat, the most recently recognized
addition to this royal cosmic zoo is the faint bluish emission from Ou4, the
Giant Squid Nebula.
Near the lower right edge of the frame, the suggestive
dark marking on the sky cataloged as Barnard 150 is also known as the
dark Seahorse Nebula.
