The Eagle and Swan Nebulas
in Hydrogen-alpha |

About This Photograph
The Eagle and Swan nebulae are two star-forming regions straddling the constellations Sagittarius and Serpens Cauda (the "Tail of the Serpent"). In this image, a special filter was used to isolate only the light emitted by hydrogen atoms, which are energized by the clusters of newborn stars within the nebulae.
