LOFAR stations consist of hundreds of antennas spread across a field about the size of a football field. They pick up radio waves at frequencies from just above and below FM radio at 10-90 MHz and 110-240 MHz. Once the raid waves have been detected, they are send by fibre optic cables to a supercomputer centre in Holland, where images are created.

The images below are of LOFAR stations in the UK and Germany. With funding from Science Foundation Ireland, we will install a LOFAR station in Birr in Spring/Summer 2017.
