  • From the NASA press release: “Kepler Mission scientists will reveal the space telescope’s latest discoveries at a news briefing in Washington on Monday, Jan. 4, 2010. The announcement will be made at 10 a.m. PST (1 p.m. EST) at a news conference during the 215th national meeting of the American Astronomical Society (AAS) at the Washington Marriott Wardman Park hotel.”
  • From ASU: “According to research published online in the Dec. 31 issue of Science Express and in the Jan. 22 issue of Science magazine by Greg Brennecka, a graduate student in the School of Earth and Space Exploration (SESE) at Arizona State University (ASU), the 238U/235U ratio can no longer be considered a constant in meteoritic material. Any deviation from this assumed value causes miscalculation in the determined Pb-Pb age of a sample, meaning that the age of the Solar System could be miscalculated by as much as several million years. Although this is a small fraction of the 4.57 billion year age of the Solar System, it is significant since some of the most important events that shaped the Solar System occurred within the first 10 million years of its formation.”
