Sh 2-7 is an emission nebula around the star Delta Scorpii in the constellation Scorpius. It lies next to a large reflection nebula, Sh 2-1.

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.
