Yes. Many countries around the world test nuclear bombs frequently. Most of these tests are underground or under water for secrecy reasons. The only other nuclear explosion used in war was the bombing of Nagasaki by the Americans, about a week after Hiroshima. The awsome (I use that word in its old-fashioned sense) effects of those two explosions caused the Japanese to surrender and World War Two to come to an end.
Yes. There have been several tests establishing this beyond a doubt, including the actual detonation of nuclear devices. It's currently prohibited by international treaties, though, since the tests produced new radiation belts and resulted in damage to the electronics of several satellites that passed through the belts. The radiation belts also produced bright auroral displays in both the north and south (until the belts finally disbursed). At least one manned US spaceflight had to be delayed following one of these tests for fear the capsule would pass through the radiation belt and result in overexposure to the astronauts.
On a missile? No, the only nuclear weapons ever used in war were the 2 aerial bombs dropped by B-29 bombers on Japan to end WW2. All the nuclear tipped missiles ever launched with live warheads were tests, either air defense missiles or high altitude effects shots.

Yes, nuclear fuel can be used for space ships to generate power for long-duration missions. Radioisotope thermoelectric generators (RTGs) and nuclear fission reactors are two types of nuclear power sources that have been used in space missions to provide electricity and heat for spacecraft and scientific instruments. However, the use of nuclear fuel in space missions presents challenges related to safety, regulations, and potential environmental impacts.
The sun is a star, and it is also a nuclear fusion reactor. It is fusing hydrogen into helium to create energy via what we call the proton-proton nuclear reaction. Our local star has been doing this for billions of years, and will continue to do so for billions more.
There is no record of a nuclear explosion occurring on November 6, 2010. If there had been a nuclear explosion, it would likely have been a significant event that would be widely documented.
Yes, Hiroshima, Nagasaki were both bombed with Nuclear weaponsChernobyl was a nuclear powerplant that suffered a meltdown, and a nuclear explosionAnd there were countless Nuclear testsThere was NO nuclear explosion at Chernobyl! The explosion was a steam explosion that blew the roof off the building and maybe 1/4 of the reactor contents up in the air, all immediate debris landed within a short distance of the plant. Then the graphite moderator of the reactor core caught fire carrying radioactive smoke that dropped fallout on millions of surrounding square miles. If it had had a containment building as all US nuclear power plants are required, to the steam explosion and fire would have been completely contained with no offsite contamination!The number of nuclear tests is quite countable, see: Swords of Armageddon by Chuck Hansen.
There has never been a nuclear explosion in the state of Texas
Hiroshima and Nagasaki are the only two cities to have been bombed with a nuclear bomb.
Hiroshima and Nagasaki
There were no reports of a nuclear explosion in Germany between 1990-1992. Germany does not have a history of nuclear weapons testing and there have been no instances of nuclear explosions in the country during that time period.
Only two cities in Japan have been attacked with nuclear bombs at the end of WW2: Hiroshima and Nagasaki.
There have been many nuclear explosion in the US in places like, Nevada and New Mexico. In anger against the US no. Japan still remains the only country in the world to be bomb in anger with nuclear weapons.
August 6, 1945 - Hiroshima Japan
Nuclear weapons have been used in war twice- both times in 1945, when the US bombed the Japanese cities of Hiroshima and Nagasaki.
Hiroshima 1945. For peaceful purposes, Calder Hall UK 1956
If you mean weapons in combat: Hiroshima and Nagasaki. If you mean something else, clarify the question.
