Space telescopes as a research area encompass the scientific and technical study, design, deployment, and utilization of astronomical observatories operating above Earth’s atmosphere to access wide spectral ranges (e.g., ultraviolet, X-ray, gamma-ray, infrared) and achieve high-precision photometry, spectroscopy, and imaging. The field addresses orbital dynamics, thermal and structural stability, detector and optics optimization, contamination control, and data calibration pipelines. Research includes mission architecture, survey strategies, multi-messenger and time-domain coordination, and methodologies for extracting cosmological, stellar, and planetary parameters from space-based observations, as well as technology development for next-generation observatories and constellations.
Today, the European Space Agency's gamma-ray telescope ends its observations. During its 22 years in space, Integral has reshaped our view of the most dramatic events in the universe. The high-energy observatory played a ...
