Pokharan-II refers to test explosions of five nuclear devices, three on 11 May and two on 13 May 1998, conducted by India at the Pokhran test range. Read more
Forensic analysis of the debris left after a nuclear explosion could yield crucial evidence about the composition and the origin of the bomb, say scientists. A US team examined Trinitite, the glassy ground debris from the first-ever nuclear test that the US Army conducted in 1945 in New Mexico. They used advanced analytical techniques to reveal details about the materials used to construct the bomb Read more
Little Feller II and Little Feller I were code names for a set of nuclear tests undertaken by the United States at the Nevada Test Site on July 7 and July 17, 1962 as part of Operation Sunbeam.
Starfish Prime was a high-altitude nuclear test conducted by the United States of America on July 9, 1962, a joint effort of the Atomic Energy Commission (AEC) and the Defence Atomic Support Agency (which became the Defence Nuclear Agency in 1971). Launched via a Thor rocket and carrying a W49 thermonuclear warhead (manufactured by Los Alamos Scientific Laboratory) and a Mk. 4 reentry vehicle, the explosion took place 400 kilometres above a point 31 kilometres southwest of Johnston Island in the Pacific Ocean.

Fenced crater stands testimony to first nuclear test
A large crater in this remote area in the desert state of Rajasthan is testimony to India's first nuclear test which was carried out on this day in 1974. Locals still remember the impact of the test which left a crater which is now protected by fencing. The test, which also brought the area into international spotlight, was carried out by the Indira Gandhi Government and officially called 'Smiling Buddha'. Read more
In a significant breakthrough, scientists have isolated an exotic radioactive gas which they claim would make it easier to detect underground nuclear tests from air samples. A global network of monitoring stations constantly samples the air for signs of underground nuclear tests. One thing the stations look for is the radioactive gas xenon-133. Read more
