The Lick Observatory Supernova Search (LOSS) conducted with the 0.76-m Katzman Automatic Imaging Telescope (KAIT) has been by far the world's most successful search for very nearby supernovae, having discovered over 700 of them during the past decade. The search and its results will be described. LOSS supernova rates as a function of host-galaxy Hubble type will be presented. As an aside, KAIT's utility in rapidly obtaining follow-up observations of the optical afterglows of gamma-ray bursts will also be illustrated. Finally, some follow-up studies of supernovae will be described, concentrating on several objects having massive progenitors. The extremely powerful SN 2006gy is perhaps the first pair-instability SN ever observed and could be a link to the earliest stars. SN 2006jc is a peculiar Type Ib supernova that had a luminous outburst 2 years before explosion and whose progenitor was probably a Wolf-Rayet star.

Subject: Dark Energy and the Runaway Universe

Observations of very distant exploding stars (supernovae) show that the expansion of the Universe is now speeding up, rather than slowing down due to gravity as expected. Other, completely independent data strongly support this amazing conclusion. Over the largest distances, our Universe seems to be dominated by a repulsive "dark energy" --- an idea Einstein had suggested in 1917, but renounced in 1929, anecdotally as his "biggest blunder." Dark energy stretches the very fabric of space itself faster and faster with time. But the physical origin of dark energy is unknown, and is often considered to be the most important unsolved problem in physics; it probably provides clues to a unified quantum theory of gravity.
