Signal detected from the first stars in the universe, with a hint that dark matter was involved

Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early interaction with dark matter.

Details of the detection are revealed in a paper published today in Natureand tell us these stars formed only 180 million years after the Big Bang.

It’s potentially one of the most exciting astronomical discoveries of the decade. A second Nature paper out today links the finding to possibly the first detected evidence that dark matter, thought to make up much of the universe, might interact with ordinary atoms.
