X-ray Astronomy:
The study of electromagnetic radiation of wavelengths shorter than ultraviolet radiation but longer than gamma-rays. The Earth’s atmosphere makes viewing celestial objects difficult from the ground, so objects observed through X-ray must be observed through satellites and rockets attached with X-ray antennas.
