Handling astronomical data from the world's largest telescope

Once fully operational, the Square Kilometre Array radio telescope could produce data at a rate more than 100 times greater than current global internet traffic. Successful handling of this unparalleled data deluge will be key to the project's ability to find answers to some of the most complex puzzles in astronomy.

Fleeting stellar unions, and feisty red outbursts

A recently published study from the University of Alberta, Canada, examines what happens when binary stars come together. The research, published in the journal Science, has also shed ‘light’ on where mysterious cool and red outbursts, called intermediate-luminosity red transients, originate form.
