Radio telescopes stamp their mark across the world BY MATHIEU ISIDRO (SKAO) Postage stamps generally feature an illustration of persons, events, institutions, or natural realities that symbolize a nation’s traditions, values, and history. It is therefore perhaps unsurprising that radio telescopes, as the iconic cutting-edge engineering structures that they are, have long featured on postage stamps around the globe. In honour of World Post Day on 9 October, we therefore took a little tour of this subgenre of philately (the study and collection of stamps) featuring many SKA pathfinder and precursor telescopes, from Cold War era stamps featuring the Lovell Telescope, to current stamps, like the one marking the inauguration of FAST, the World’s largest single dish radio telescope.

Germany’s Effelsberg 100m Radio Telescope celebrated its 50th birthday in 2021, and marked it by supporting NASA’s Perseverance spacecraft landing on Mars, picking up radio signals broadcast during the tricky descent.
A 1965 stamp from Sharjah (now in the United Arab Emirates) depicts the 76m Lovell Telescope at Jodrell Bank in the UK. The city was a British Protectorate at the time. ISSUE
