Sir Martin Ryle - In 1959 the Radio Astronomy Group at the University of Cambridge led by Professor Martin Ryle published the Third Cambridge Catalogue of Radio Sources (3C) which led to the discovery of the first quasi-stellar object (quasar). It was a landmark map of stellar sources and Ryle’s work led to confirmation of the Big Bang Theory. Ryle was knighted in 1966 and awarded the Nobel Prize for his work in 1974.
"Last former Yugoslav republic to get independent in 2006, they already issued their first Europa stamps in 2005."
"Montenegro issues are most of the time composed of a set with a souvenir sheet and sometimes a booklet."
"The first issue of 2005 is very rare and reached value records."
"Portugal issue Europa stamps since 1960. From 1961, 1962 and 1963, they didn't follow the common design, having their own."
"Since 1977 they also issue a souvenir sheet with every issue."
"The autonomous island of Madeira and the archipelago of the Azores issue also Europa stamps since 1981. Their issuing programme is closely linked with the one of Portugal."
