MAG 29

The red giant MAG 29 lies in the Sculptor Dwarf galaxy, a sperical satellite of our Milky Way. It is a carbon star, this is a star which at the end of its life produces carbon in large amounts. A part of this carbon gets emitted into space as dust. The star is interesting, because the Sculptor Dwarf galaxy contains hardly heavy elements and therefore reminds of the conditions in the early universe. So MAG 29 shows, that at an early point in the universe carbon could be produced in large amounts, which enriched the galaxies with dust.
