g MESSAGE - In 2001, California astronomers broadened the search for extraterrestrial intelligence with a new experiment to look for powerful light pulses beamed our way from other star systems. Scientists from the University of California's Lick Observatory, the SETI Institute, UC-Santa Cruz, and UC-Berkeley used the Lick Observatory's 40-inch Nickel Telescope with a new pulse-detection system capable of finding laser beacons from civilizations many light-years distant. Unlike other optical SETI searches, this new experiment is largely immune to false alarms that slow the reconnaissance of target stars. See article.
g COSMICUS - A newly discovered comet will make its first-ever journey into the inner solar system later this year. Comet ISON will appear bright in the night sky starting in November 2013. See article.
