Observatory Photographs

Peter Jonker is Professor of High Energy Astrophysics at Radboud University in Nijmegen, The Netherlands. He studies black hole formation and evolution. Since childhood, he has enjoyed looking up at the sky and wondering about the complexities of life. During observation runs at the telescopes in La Silla, Chile, dusk is always a busy period, with everyone preparing for the night ahead. At the same time, the surrounding mountaintops and the setting sun often provide a stunning spectacle, so his keeps his camera always on hand. He used an Apple 13 mini with a broad 26 mm camera to take these photographs.
