beyond the ends of the N–S and E–W solar arrays, which comprised the Fleurs Synthesis Telescope with a resolving power of 20 arc seconds, used in the 1970s and until its closure in 1988 studying individual radio sources but particularly large radio galaxies, supernova remnants and emission nebulae. Following the success of this design, Mills built another large cross antenna, the Molonglo Cross Telescope, near Canberra. Other large cross-type radio telescopes were later built in the United States, Italy, Russia, and Ukraine.
