Officials with the W.M. Keck Observatory hope its upcoming 20th anniversary will spur renewed interest in the telescope in the form of additional funding. The sequestration in Washington, D.C., could threaten $6.5 million -- a quarter of the telescope's budget -- that the observatory receives from the U.S. National Science Foundation. Keck advocates hope its philanthropists will make up some of the expected shortfall. "We are hoping that this anniversary will put a clarion call that says this is something of value in our world," said Debbie Godwin, director of advancement for Keck's foundation.
