Summary

Description
English: At a distance of 1.7 million light years away, NGC 6822 is literally right around the corner. This galaxy is a dwarf with a mere 10 million stellar members in its ranks. Note the "bubble" of gas in the top right corner. This bubble was probably caused by stars that formed from their natal gas cloud. Upon their birth, the extra gas in the cloud was expelled into space- pushed out by the energetic stellar winds of the baby stars. Since this galaxy (especially on the outskirts) does not have much in the way of internal motions, the bubble of gas continues to expand without anything disrupting it. (For those with good eyes... there are actually a few other bubbles in this image as well).This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
