Astronomy: Dawn after the dark age
Richard McMahon1
Abstract
The latest surveys provide evidence for one, maybe two, galaxies farther back in cosmic time than ever detected before. But does the fact that we don't see more mean these are the very first galaxies to be formed?
Determining when the first stars and galaxies formed is a matter of profound importance: fuelled by primordial hydrogen, these bodies triggered the nucleosynthesis of the heavier elements, such as carbon, nitrogen and oxygen, that are the basis of life. By studying the first galaxies, we can also hope to understand how the Universe formed and evolved, and detect the younger progenitors of galaxies like our own Milky Way.
