Comet Lovejoy through Mörby Castle Ruins

As seen on Astronomy Picture of the Day, comet Lovejoy C/2013 R1 is photographed through ruins of ancient Mörby Castle in Sweden. With a green-glowing coma and tails trailing several degrees in this telephoto image, the comet was visible to the unaided eye from a dark location at that time. Click on the second photo to see another single-exposure image of the comet that shows the tail slightly longer.
