The Great Supernova Hunt
Join The Hunt
The Catalina Real-Time Transient Survey finds supernovae
by comparing catalogs of objects (stars + galaxies) detected
in a series of images.
Many of the supernova occuring bright galaxies are
not present in these catalogs because they occur on
top of a bright galaxy.
These SN can be found by subtracting pairs
of matched images, to look for changes, or by
simply comparing the pairs of images visually.
We take pictures of hundreds to thousands
of bright galaxies every night and cannot
look at every image by ourselves.
We expect roughly one new SN discovery for
every 1000 images.
