A team of South African scientists using the South African Radio Observatory's (SARAO), MeerKAT radio telescope, has spotted a rare and extremely faint radio glow coming from a huge cluster of galaxies about 7 billion light-years away. 

This type of glow - called an ultra-steep-spectrum radio halo - is the most distant one ever found. The discovery, led by Isaac Magolego, a PhD student at the University of the Witwatersrand, supervised by Professors Roger Deane and Kshitij Thorat, from Wits and the University of Pretoria, has been accepted for publication in Monthly Notices of the Royal Astronomical Society: Letters. The student project is supported by the SARAO.

For more on this, Magolego joins us on the line.
