I was scrolling through my facebook feed a few weeks ago, and a beautiful photograph came up, purporting to be the Butterfly Nebula. I am grateful to the the person who, in the comments pointed out that this was an AI generated image. This meant that I then went down a very happy rabbithole to find out what the real images of the Butterfly Nebula were like.
The image I came across on the Hubble website which is a complete spectrum photograph of light, from near-ultraviolet to near-infrared of NGC 6302. The image shows that the star or stars in the centre are in their death throws, ejecting huge amounts of gas, which is producing the amazing wing like projections.
These rolags are made from a mixture of 18.5 micron merino, 21 micron merino with lashings of white Eris silk and silver Angelina.
The merino in this blend will felt.
