X-ray astronomy: energies from 0.1 keV to 100 keV,nd dispersing X-rays. The use of CCDs and cryogenic detectors for non-dispersive spectroscopy is also discussed. The present state of the art in the topic is presented through the description of several recent and current space missions in both the solar and cosmic fields.

Innocence

High-accuracy positioning: astrometry,ircumstances, such as additive noise and finite pixel size. Its application is discussed in relation to different space-astrometry techniques including grid modulation, direct imaging, and interferometry.

Strength

The visible and near-infrared domain,s of view, dynamic range and complete spectral coverage. This chapter discusses the inherent limitations of ground-based astronomy that are overcome by space observations and lists some of the spacecraft that have demonstrated these advantages for scientific study.

Imaging through Compton scattering and pair creation,is purpose, the omni-directionally sensitive BATSE instrument used its capability to monitor hard X-ray sources > 20 keV by means of Earth occultation). Since 2008 the high-energy telescope . performs continuous deep all-sky surveys at gigaelectronvolt energies. Finally, the outlook for future Compton and pair-creation telescopes is given.

Antagonism

Far-infrared imaging and spectroscopic instrumentation,ission, ., launched in May 2009. This mission also makes use of heterodyne techniques for very high spectral resolution. We review the principle of heterodyne detection and briefly describe the HIFI instrument on . and how it takes the subject of high-resolution spectroscopy into a new era.
