Cosmic X-ray Sources

Science. 1965 Jan 22;147(3656):394-8. doi: 10.1126/science.147.3656.394.

Abstract

Eight new sources of cosmic x-rays were detected by two Aerobee surveys in 1964. One source, from Sagittarius, is close to the galactic center, and the other, from Ophiuchus, may coincide with Kepler's 1604 supernova. All the x-ray sources are fairly close to the galactic plane.
