Observation data: J2000.0 epoch | |
Right ascension | 16h 21m 11.31s |
Declination | -25d 35m 34.05 |
Distance | 568 ly (174 pc) |
Apparent magnitude (V) | 2.89 |
Constellation | Scorpius |
Designations | Gum 65, LBN 1101, HD 147165, IRAS 16181-2528 |
Sh2-9, also known as Gum 65, is combination emission and reflection nebula in the Scorpius constellation, surrounding the multiple star system Sigma Scorpii. Sigma Scorpii is 1° to the northwest of Messier 4, [1] [2] and the nebula can be easily seen with small telescopes.
Sharpless 9 is a red emission nebula that surrounds the star Sigma Scorpii. [2] It is thought the star Sigma Scorpii, a variable giant star, is ionizing this region. [3] It is also recorded as reflection nebula C130. [4]
This region is noted as both an emission and reflection nebula, although sometimes only one aspect is noted. [5] [2]
The magnitude 1.1 Antares is 2° to the southeast of this nebula. [2]
One of strongest 2.3 GHz sources in the region coincides with Sharpless 9. [4]
There is a radio source on the edge, and it has been proposed that this is because there is a collision between this nebula and the dark nebula Kh 527. [4]
