A UK observatory has shared what s believed to be the longest-exposure image ever taken, lasting longer than eight years.
But the image, shot at the University of Hertfordshire s Bayfordbury Observatory, wasn t made with any high-tech photo equipment.
Regina Valkenborgh, a graduate art student at the college at the time, just used a simple pinhole camera made out of an empty beer can and some photographic paper.
It shows 2,953 arced trails as the sun rose and set over for 97 months between August 2012 and September 2020.
The dome of Bayfordbury s oldest telescope is visible on the left of the photo while an atmospheric gantry, a structure built halfway through the exposure process, can be seen toward the right.
