Old-looking galaxy in a young universe: Astronomers find dust in the early universe

Dust plays an extremely important role in the universe — both in the formation of planets and new stars. But the earliest galaxies had no dust, only gas. Now an international team of astronomers has discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which could form planets.
