The history of X-ray astronomy begins in the 1920s, with interest in short wave communications for the U.S. Navy. ... finding charts, X-ray luminosities, ...
X-ray astronomy is an observational branch of astronomy which deals with the study of X-ray observation and detection from astronomical objects. X-radiation is absorbed by the Earth's atmosphere , so instruments to detect X-rays must be taken to high altitude by balloons , sounding rockets , and satellites .
The Uhuru satellite, designed to map the sky at X-ray wavelengths, is launched by NASA. The existence of X-rays from the Sun and a few other stars has already been found using rocket-launched experiments, but Uhuru charts more than 300 X-ray sources, including several possible black holes.

1978 – Einstein High Energy Astronomy Observatory x-ray telescope satellite; 1979 – UKIRT 150-inch (3.8 m) infrared reflecting telescope begins operation, located at Mauna Kea Observatory, Hawaii; 1979 – Canada-France-Hawaii 140-inch (3.6 m) optical reflecting telescope begins operation, located at Mauna Kea Observatory, Hawaii
The X-ray colors represent the temperature of the X-ray emission from each star: hot stars are blue-white and cooler stars are yellow-red. The brightest object in the optical image is the full moon, which is also in the X-ray image. The X-ray image was actually obtained by the ROSAT satellite during the All-Sky Survey phase in 1990–1991.
