Last Wednesday a further 60 satellites were launched as part of SpaceX's Starlink project. Eventually many thousands of these small satellites will ring the Earth, providing Internet access to almost the entire globe. This is however problematic, as they interfere with astronomy given their light pollution. Willie Koorts shows us how to image the 'String of Pearls' in his youtube videos which you can find on https://www.youtube.com/user/SterremanWillie/videos.

Looking up - 01 May 2020

Five minutes at the end of each week explores the big and the small questions in astronomy, cosmology, and space science. Hosted by Kechil Kirkham, no subject is too big or too small, and experts are regularly brought on board to illuminate and excite. Cape Town is the place to be for astronomy, with some of the largest telescopes in the world housed or being built not too far away. Looking Up takes advantage of the shoals of scientists and engineers working on the planet’s most advanced astronomy projects, who live and work right here in the Mother City. Kechil has recently acquired an MPhil in Space Studies at the University of Cape Town, and works in South Africa’s space industry on the Square Kilometre Array radio telescope.
