英文摘要:
On June 1, 1990 the German X-ray observatory ROSAT started its mission to open a new era in X-ray astronomy. Doubtless, this is the most ambitious project realized up to now in the short history of this young astronomical discipline. Equipped with the largest imaging X-ray telescope ever inserted into an earth orbit ROSAT has provided a tremendous amount of new scientific data and insights.
