Covid-19 is seriously impairing travel. While the job that pays the bills used to come with lots of business travel, I’ve been restricted to work from home since beginning of March. Also private travel is significantly reduced in Europe, and the streets of Nuremberg haven’t seen many visitors either. But our night sky has been graced by a very special visitor from outer space, comet Neowise. Properly socially distanced, it passed our planet at a distance of 103 million km or 64 million miles.
