I wonder how dynamic this place is. I know it's light years across, but is there any chance to see movement within the smallest structures if we were to revisit the same image on a ~yearly timescale?
From the article: "The gas clouds surrounding the Horsehead have already dissipated, but the jutting pillar is made of thick clumps of material that is harder to erode. Astronomers estimate that the Horsehead has about five million years left before it too disintegrates."
