I learned about WR class stars from this post. They are apparently the brightest of stars and the James Webb Space Telescope has already captured some stunning images[0] of WR stars.

If you view the full-res[1] of the linked image, if you look carefully at the bottom-left of the purplish plume, you will see what looks like an entirely separate yellowish-green spiral galaxy. Mind blowing.
