A Scorpius Mosaic

in Hydrogen Alpha Light


This 3-panel mosaic depicts the region near the stinger of the constellation of Scorpius. In the sky, this region lies close to where we would observe the galactic center, and our perspective here shows the extensive nebulosity that lies within the galactic plane. The two prominent objects here are Cat's Paw Nebula (NGC 6334, top) and War and Peace Nebula (NGC 6357, bottom). This image was shot through hydrogen alpha filters, which highlights regions where ionised hydrogen is present. Ionised hydrogen usually correlates with high star formation activity, which is observed within these dense clouds of star-forming material.
