Supernovae, Exoplanets, Black Holes, and New Technology: Frontier Research at UC's Lick Observatory Lick Observatory is a vibrant research facility, and a primary base for the University of California's astronomy education and outreach efforts. Cutting-edge fields include supernovae, Earth-like exoplanets, supermassive black holes, and laser-guide-star adaptive optics. Come find out about discoveries and public outreach being done at Lick, now partially supported by a generous gift from Google | Making Science, and how you can help sustain these activities.
We expected the attractive force of gravity to slow down the rate at which the Universe is expanding. But observations of very distant exploding stars (supernovae) show that the expansion rate is actually speeding up, a remarkable discovery that was honored with the 2011 Nobel Prize in Physics to the teams' leaders. Over the largest distances, the Universe seems to be dominated by a repulsive "dark energy" -- an idea Albert Einstein had suggested in 1917 but renounced in 1929 as his "biggest blunder." It stretches space itself faster and faster with time. But the physical origin and nature of dark energy, which makes up about 70% of the contents of the Universe, is probably the most important unsolved problem in all of physics; it may provide clues to a unified quantum theory of gravity. ...
Alex Filippenko received his Ph.D. in astronomy from Caltech in 1984 and joined the University of California, Berkeley faculty in 1986, where he is currently the Richard and Rhoda Goldman Distinguished Professor in the Physical Sciences. An observational astronomer who makes frequent use of the Hubble Space Telescope and the Keck 10- meter telescopes, his primary areas of research are supernovae, active galaxies, black holes, gamma-ray bursts, and the expansion of the Universe. Filippenko's research accomplishments, documented in more than 700 published papers, have been recognized with several major awards, including election to the US National Academy of Sciences. One of the world's most highly cited astronomers, he was the only person to have been a member of both teams that revealed th...

How do we know where to find supernovae? What's driving the search for dark energy and dark matter? How can we learn about parts of the universe that are impossibly far away? Come join Alex Filippenko, an American astrophysicist and Professor of Astronomy from the University of California, Berkeley, to find out. Professor Filippenko is the only person who was a member of two teams that discovered we have an accelerating universe, and its implied existence of dark energy. This discovery resulted in the 2011 Nobel prize for physics being awarded to the leaders of the two project teams.

World-renowned astronomer and prize-winning professor of astronomy at the University of California, Berkeley, Alex Filippenko, explores some of the mysteries of the universe at a special lecture at the Santa Barbara Museum of Natural History. Filippenko discusses observations of very distant exploding starts called super-novae that provide intriguing evidence that the expansion of the universe is now speeding up. Over the largest scales of space, the universe seems to be dominated by a repulsive "dark energy" of unknown origin, stretching the very fabric of space itself faster and faster with time.
