Science news this week: Overdue earthquakes and star-shaped brain cells


This week’s science news saw us looking deep into the cosmos and the depths of our oceans.

To understand the universe today, we need to look back at its earliest epoch, a period about 13 billion years ago known as the cosmic dawn. Until now, space-based telescopes have been our only way to peer back this far, but this week astronomers detected traces of light left by the first stars using a ground-based telescope — a feat scientists previously thought was impossible.
