Scorpius X-3

There are 88 official constellations that the International Astronomical Union (IAU) has used to divide the celestial sphere into irregularly shaped boxes. One of these is Scorpius. Using detectors placed above the Earth's atmosphere, X-radiation from X-ray sources has been discovered coming from Scorpius. The first two such X-ray sources were designated Scorpius X-1 (Sco X-1) and Scorpius X-2 (Sco X-2).

The position for Scorpius X-3 has been confirmed several times at J1950 RA Dec . Unlike Sco X-1 and X-2, Sco X-3 has no visual counterpart. The position of Sco X-3 is Coincident with an extended H II emission region (No. 114) which May Be the remnant of a supernova explosion, possibly the one observed by Albumazar in A.D. 827.

Scorpius XR-3 has been observed at J1950 RA Dec .
