A machine astronomer could help us find the unknowns in the universe

It’s almost impossible for any human to spot something unknown or unusual in the massive amount of data collected by our telescopes. So we’re teaching an intelligent machine to search the data for us.

A faster response needed to see Fast Radio Bursts in the universe

Astronomers are trying to improve their hunt for rapid bursts of radio emission in the universe called Fast Radio Bursts (FRBs) so they can better observe these mysterious events, which are thought to…
