The German institute is pouring R150-million into building and installing radio receivers
on the MeerKAT radio telescope. The project, it says, will grant its scientists access to a
world-class facility and its unique unrestricted view on our galaxy, and will boost
MeerKAT's scientific potential even further.
The first Africa Data Challenge calls for data-driven projects that have a practical, human impact in Africa, which is falling behind in the race for scientific development. Innovators can pitch their ideas at the #ScienceAfrica UnConference in London.
