The High Energy Astronomical Observatory HEAO-2, launched in November, 1978, carries a 58-cm X-ray telescope which can be pointed with an accuracy of one minute of arc and has a resolution of four seconds of arc, an improvement of 1000 times over the X-ray detectors used previously. To date the observatory has examined more than 3000 celestial fields and in each field at least one X-ray source has been recorded. X-ray emissions have been measured from stars throughout the color-magnitude range and new extragalactic sources have been registered. Different distributions of X-ray emitting gas between galaxies found by the observatory provide a way to classify clusters of galaxies. X-ray emissions have been recorded from the most distant of the known quasars, which suggests that most of the X-ray background noise may be due to quasars too distant to be recorded individually.
