I was happy to deliver a talk on Black Holes last Wednesday March 11, in the public library in Boutersem, Belgium.
Talk on Black Holes
Timelapse through the Corona night
With a Color camera, a ZWO ASI 290MC, this is how the night looked, from March 15 on March 16th 2020. Some airplanes fly over, but not as many as usual. It also clearly shows how the public lighting switches off – and at the end of the night switches on again. At 1:18 there is a small meteor flying briefly from south to north. At the end of the night, also the Moon and I guess Jupiter shine through the Walnut tree in the garden.
