  The Swift Gamma Ray Burst Explorer has proven to be an incredible platform
for studying the multiwavelength properties of supernova explosions. In its
first ten years, Swift has observed over three hundred supernovae. The
ultraviolet observations reveal a complex diversity of behavior across
supernova types and classes. Even amongst the standard candle type Ia
supernovae, ultraviolet observations reveal distinct groups. When the UVOT data
is combined with higher redshift optical data, the relative populations of
these groups appear to change with redshift. Among core-collapse supernovae,
Swift discovered the shock breakout of two supernovae and the Swift data show a
diversity in the cooling phase of the shock breakout of supernovae discovered
from the ground and promptly followed up with Swift. Swift observations have
resulted in an incredible dataset of UV and X-ray data for comparison with
high-redshift supernova observations and theoretical models. Swift's supernova
program has the potential to dramatically improve our understanding of stellar
life and death as well as the history of our universe.
