Explanation:
This colorful skyscape
spans about three full moons across nebula rich
starfields along the plane of
our Milky Way Galaxy toward the royal northern constellation
Cepheus.
Near the edge of the region's massive molecular cloud some 2,400
light-years away, bright reddish emission region
Sharpless
(Sh)2-155 is at the center of the frame, also known as the
Cave Nebula.
About 10 light-years across the cosmic cave's bright walls of
gas are ionized by ultraviolet light from the hot young stars around it.
Dusty bluish reflection nebulae,
like vdB
155 at the left, and dense obscuring clouds of dust also abound on the
interstellar canvas.
Astronomical
explorations have
revealed other
dramatic
signs of star formation,
including the bright reddish fleck of
Herbig-Haro
(HH) 168.
At the upper left in the frame, the Herbig-Haro object emission is
generated by energetic jets from a
newborn star.
