Joe Pawsey was not only a pioneer of radio-astronomy in the 1940s,
he is also credited with having named this new field of research
"radio-astronomy". In October 1945, Pawsey conducted the first
successful radio astronomy experiment at the former wartime radar
station on the Collaroy Plateau, Sydney. The 74th anniversary of this
event was commemorated by three generations of the Pawsey family
visiting the Pawsey Supercomputing Centre in Perth. Pawsey, together
with Ruby Payne-Scott and Lindsay McCready, observed the sun and found
both steady radio emissions, and strong, variable radio emissions that
originated from the vicinity of large sunspots. Joseph Pawsey’s son
Hastings Pawsey, with his wife, daughter and two granddaughters
toured the Pawsey Centre with representatives of the Australian
radio astronomy community earlier this month. (Image credit: Pawsey
