Trinity was the code name of the first detonation of a nuclear device. This test was conducted by the united states on july 16 1945. It was on this day that a plutonium bomb was tested at a site in los Alamos.
Hoisted atop a 50 metre tower, the plutonium device detonated at precisely 5.30 am over the new mexico desert, releasing 18.6 kilo tonnes of power, instantly vaporizing the tower. Seconds after the explosion, came an enormous blast. A ball of fire tore up into the sky, and then was surrounded by a giant mushroom cloud.
Scientists figured that the temperature at the centre of the explosion was three times hotter than at the centre of the sun. thus the nuclear age has begun.
