The nuclear bomb, that devastatingly powerful world killer of a weapon, has been around for 70 years. The first nuclear bomb -- Trinity -- was detonated in a test in New Mexico in 1945, a month later the US Army dropped nukes on Hiroshima and Nagasaki and the world was never the same. Here's an interesting visualisation that shows every nuclear bomb that's been detonated on our planet.
The colour red means atmospheric, yellow is underwater and blue is underground. Put together by Orbital Mechanics, the visualisation also details the date, location and strength of each nuclear detonation. It is haunting.
