Extreme ultraviolet astronomy : a selection of papers presented at the First Berkeley Colloquium on Extreme Ultraviolet Astronomy, University of California, Berkeley, January 19-20, 1989 /
The field of extreme ultraviolet astronomy will see two major satellite observatories to be launched in 1991, one by ESA (ROSAT mission), one by NASA (EUVE mission). These Proceedings discuss the potential for EUV Astronomy, results from recent missions, approved and possible future missions and new...
