Contrast emotions evoked from a single image (Visual Research)

This picture was captured on August 9, 1945 with America initiating a nuclear attack on Nagasaki, Japan during the end of WWII.  The reason I chose this picture because somehow it evokes contrast emotions. It highlights the horrifying devastation and doom of the catastrophe but at the same time the cloud formation several feet above in the sky creates a beautiful imagery. The enveloping cloud in a mushroom form looks serene yet scary. There is a natural beauty in the clouds floating and taking a certain shape but the it even is a proof of one of the most tragic event of all times.
