Remarks: |
Sh2-132 is a weak emission nebula, which is
mainly excited to glow by two Wolf-Rayet stars. WR 153ab (a multiple system)
is responsible for the northern (left) red part of the image, the southern
(right) blue regions are supplied by WR 152. More information on Sh2-132

Bemerkungen: |
Sh2-132 ist ein recht schwacher Emissionsnebel, der im
Wesentlichen durch zwei Wolf-Rayet-Sterne zum Leuchten angeregt wird. Für
den nördlichen (linken) roten Teil des Bildes ist WR 153ab (ein
Mehrfachsystem) zuständig, die südlichen (rechten) blauen Regionen werden von
WR 152 versorgt. Nähere Informationen zu Sh2-132 zb.
