After radio astronomy, the next 'new astronomies' were Ulra-Violet and X-ray (followed by Gamma Ray and then Infra Red). Because of atmospheric absorption, telescopes for these frequencies require detectors based in space.
Ultra-Violet occupies that part of the Electromagnetic Spectrum immediately above visible light (in terms of frequency). It is well-known that the ozone layer protects the Earth from an excess of this form of radiation.
