India's first dedicated astronomy satellite is also one of the most versatile: it simultaneously observes the universe in X-ray, ultraviolet, and optical light — three wavelength ranges at once. AstroSat has studied the hottest and most energetic objects in the cosmos, from neutron stars to galaxy clusters, and made the first confirmed detection of ultraviolet light from a galaxy in the early universe. It represents India's full emergence as an independent player in space-based astronomy.
