When a massive star collapses at the end of its life, nearly all of
the gravitational binding energy of the resulting remnant is released
in the form of a brilliant burst of neutrinos. I will discuss the nature of the
core-collapse neutrino burst and what we can learn about particle
physics and about astrophysics from the detection of these neutrinos.
I will cover supernova neutrino detection techniques in general,
current supernova neutrino detectors, and prospects for specific
future experiments.
