Sprawling across hundreds of light-years, emission nebula IC 1396, visible on the center,
mixes glowing cosmic gas and dark dust clouds. Stars are forming in this area, only about 3,000
light-years from Earth. This wide angle view also captures surrounding emission and absorption
nebula. The red glow in IC 1396 and across the image is created by cosmic hydrogen gas recapturing
electrons knocked away by energetic starlight. The dark dust clouds are dense groups of smoke-like
particles common in the disks of spiral galaxies. Among the intriguing dark shapes within IC 1396,
the winding Elephant's Trunk nebula lies just up of the nebula's center. IC 1396 lies in the
high and far off constellation of Cepheus.
