The Sculptor Dwarf contains only 4 percent of the carbon and other heavy elements in our own galaxy, making it similar to primitive galaxies seen at the edge of the universe. Those galaxies emitted the light we now see soon after they and the universe formed. Carbon stars could have been pumping dust soon after the first galaxies were born.

most of the time it seems dust is something i am in a battle with, and i never win; sometimes, dust looks so beautiful as it floats in the air, maybe in a sunbeam; breathe it in
