Has there ever been a nuclear explosion besides Hiroshima?
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.
How many atmospheric layers does the sun have?
The Sun does not have atmospheric layers like Earth. It consists of mainly three main regions: the core, the radiative zone, and the convective zone.
How many more times is the atmospheric pressure in Jupiter's core greater than the atmospheric pressure at the earth's surface?
Earth's atmospheric pressure is measured as 1 bar. Jupiter's atmospheric pressure is 100 million bars. Therefore, it is 100 million times greater
How many nuclear warheads would it take to end life on earth?
It is difficult to determine an exact number of nuclear warheads needed to end all life on Earth as it would depend on various factors such as targeting and the size of the warheads. However, it is believed that even a small fraction of the world's nuclear arsenal could potentially cause catastrophic global consequences.
What is the difference between the suns nuclear reactions and man made ones?
The sun's nuclear reactions are based on fusion of atoms (hydrogen atoms are fused together to form helium or lithium mainly) whereas earth-bound nuclear reactions are based on fission (uranium atoms are smashed apart to form (often radioactive) fragments and energy) There has been research on earth-bound nuclear fusion for many years (JET project in the UK) and ITER, but there is still a long way to go before we can mimic the sun!
How many nuclear reactors are in the world?

Was there ever been a nuclear explosion in the US?

Yes, witness the many hundreds of nuclear power plants in the world today, most of which have operated entirely safely.
What is The impact of atmospheric phnemona on nuclear wepens?
There is no impact of weather on nuclear weapons. They are stored in secure facilities which includes shelter from the weather. Nuclear weapons however do have an impact on the weather. A nuclear blast sends dust and gas into the upper atmosphere where it blocks sun-light from making it all the way to the surface. The cumulative effect of many many many such explosions is feared to create a nuclear winter and promote the onset of a new ice-age.
