Description

The RCW Catalogue (from Rodgers, Campbell & Whiteoak) comprises 182 Ha emission regions in the Milky Way that are best observed from the southern hemisphere. This image includes RCW89 and RCW91. RCW89 is located in the centre of the image. It is thought that a white dwarf left over from a supernova has lit up the the tight knots and filaments around RCW89, giving it a strange appearance. Xray images of this area are stunning.

I can't find that much information about RCW91 (top right corner of the image) aside from the fact that it is part of a active star forming region and that it may be part of the same structure which includes RCW92 (not seen in this image).
