The section shown here is just 10% of the Subaru
Deep Field, with 22 out of 150 supernovae. Each point of light in
the image is a galaxy, consisting of tens of billions of stars
(except for the few bright spots that are nearby Milky-Way stars).
Every triplet of frames zooms in on one event,
showing the galaxy before the explosion, with the supernova in
progress, and in a digital "difference image" that isolates the
light from the supernova.
