Every nuclear detonation from 1945 to the present day, visualised

This week the world has been marking 70 years since the US dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki.

Barack Obama - who won the Nobel peace prize in 2009 for advocating nuclear non-proliferation - and the nuclear deal he oversaw with Iran have put nuclear weapons to the forefront, and Labour leadership front-runner Jeremy Corbyn has pledged to scrap Trident if elected.

This all makes a new visualisation charting every nuclear explosion ever all the more haunting. From Orbital Mechanics, every single detonation (the video counts 2,153) is mapped, from the first US tests, the Hiroshima-Nagasaki bombings, the 1961 Tsara Bomba - the most powerful nuclear weapon ever detonated, to the most recent nuclear explosion when North Korea conducted an underground test in 2009.

Watch it below (red indicates an atmospheric detonation; yellow means underground and blue is underwater).
