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

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.
