||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 probalby 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).
