It has a solid steel plate from its centre to a diameter of 17 metres,a perforated aluminium plate to a diameter of 42 metres,and the rest is a mesh of galvanised steel. The weight of the dish is 300 tonnes. This radio dish is used to observe wavelengths from 5mm to 2cm. Radio astronomy has improved our understanding of the evolution of stars and galaxies.
