IC 410

A Hatched Cocoon, IC 410 Emission Nebula in Auriga

IC410 is an emission nebula located in a large HII galactic region in the constellation of Auriga. Embedded in the nebula there is an open cluster of massive  hot newborn stars catalogued as NGC 1893.This wide field view of IC 410 shows a cocoon like structure made of the ionized hydrogen gas in the HII region.
The cocoon appears to be hatched by the erosion of the solar winds and ionization produced by the young stars within. The opening allows peeking inside and enjoying the view of the newborn stars in a very bright and colorful scene produced by the light of the hydrogen alpha (asigned to the green channel in this image), oxygen III (blue) and sulfur II (red) emission lines.
