Corrections and clarifications.
In the Research News article "Extreme ultraviolet satellites open new view of the sky" by Donald Goldsmith (14 Apr., p. 202), astronomer Stuart Bowyer was incorrectly identified as the director of the University of California, Berkeley's Center for Extreme Ultraviolet Astronomy. Bowyer was the founding director of the center and was succeeded by Roger Malina, who became acting director in 1994 and is now director. Malina is, with Bowyer, a principal investigator of the National Aeronautics and Space Administration's EUVE (Extreme Ultraviolet Explorer) mission.
