Description

A combination emission (red) and reflection (blue) nebula surrounding the star Alniyat (Sigma Scorpii), a variable giant which is believed to be ionizing this region.  The processing of this image did not bring out the reflection aspect very well.  Alniyat is 1° to the northwest of the globular cluster Messier 4, which is visible in the upper left corner.  The red giant Antares is 2° to the southeast of the nebula.   The object in the lower left corner is the globular cluster GC6144.  The light patch occupying that corner next to GC6144 is an artifact resulting from a defect in the imaging train.
