SUMMARY:The E-Nova Project: A Multi -Wavelength Initiative to Prove th
 e ejecta and Environments of Novae\, Astronomy Colloquium\, Laura Chom
 iuk\, Michigan State
DESCRIPTION:When imagining a nuclear explosion\, we often picture stro
 ng\, spherical shock waves\, like a bomb or supernova\; however\, natu
 re's most common thermonuclear explosions look nothing like this\, sho
 wing delayed and multiple phases of mass ejection that can last for mo
 nths after the nuclear fuel is ignited. These most common explosions a
 re novae---thermonuclear runaways on the surfaces of accreting white d
 warfs---and their complexities are best revealed with an intensive mul
 ti-wavelength observational program highlighting radio and X-ray data-
 --our E-Nova Project. I will discuss our recent results\, featuring ob
 servations from the newly-upgraded Karl G. Jansky Very Large Array\, a
 nd spotlighting sources like the recurrent nova T Pyx (which is challe
 nging our basic assumptions about accretion on white dwarfs) and the f
 our novae that have been detected in gamma rays to date (an emission p
 rocess that was not predicted and remains an intriguing mystery). The 
 implications for Type Ia supernova progenitors will also be discussed.
