Sh 2-7 is an emission nebula in the Scorpius constellation. The nebula is around the star Delta Scorpii. It lies next to a large reflection nebula, Sh 2-1.[1]
According to the paper Interstellar magnetic cannon targeting the Galactic halo. A young bubble at the origin of the Ophiuchus and Lupus molecular complexes, the HII region Sh 2-7 may be acting as a faraday screen, altering the polarization of the GCS. [2]
