Using Hubble's high resolution and ultraviolet sensitivity, a dense knot of dozens of ultra-hot stars has been detected in the Hubble-V nebula, each shining 100,000 times brighter than our Sun!

Hubble-V extends for about 200 light years.

A bright knot of densely packed stars shines in the centre of the image, and red nebular material flows upwards from it against black space dotted with a few stars.

Doesn't it look like a huge campfire?
