In the April Scientific American author Michael Lemonick takes us back to the cosmic dark ages, the time before the first stars and galaxies formed, in his story “The First Stars in the Universe.” Astronomers still argue over exactly how the first objects in the universe formed and what they looked like, as direct observations of a time so long ago are hard to come by. One of the major goals of the James Webb Space Telescope, scheduled to launch in 2018, is to observe the cosmic dawn. This NASA video explains how the first galaxies emerged, and how the Webb will try to catch glimpses of those first shards of light cutting through the darkness.
