Presentation

The Randonneurs des étoiles invite you to a talk on the subject of astronomy  
This lecture is presented by Karl Ludwig Klein, emeritus astronomer at the Paris-Meudon Observatory. It is entitled ‘The Two Histories of Sunspots’.

In the 17th century, sunspots were the subject of fierce debate: were they really spots? Or were they small planets orbiting the Sun? We now know their true nature
