A Difficult Photo

This is a photo of the sun:


But it wasn't taken by your average camera. It's a neutrino-detector in Japan, looking for those tiny, almost-massless particles travelling at ridiculous speeds. The sun spits out a lot of them, hence they can be 'photographed'. Even more insane is that the photo took 503.8 days to capture. Talk about exposure.

Crazier still, it was taken through the earth. Through the earth. 8000 miles of rock. Through.
