what is its origin?
Along with all elements having atomic weights higher than that of iron, uranium is only naturally formed by the r-process in supernovae and neutron star mergers.
Uranium
Along with all elements having atomic weights higher than that of iron, uranium is only naturally formed by the r-process (rapid neutron capture) in supernovae and neutron star mergers. Primordial thorium and uranium are only produced in the r-process, because the s-process (slow neutron capture) is too slow and cannot pass the gap of instability after bismuth. Besides the two extant primordial uranium isotopes, U and U, the r-process also produced significant quantities of U, which has a shorter half-life and has long since decayed completely to Th, which was itself enriched by the decay of Pu, accounting for the observed higher-than-expected abundance of thorium and lower-than-expected abundance of uranium. While the natural abundance of uranium has been supplemented by the decay of extinct Pu (half-life 0.375 million years) and Cm (half-life 16 million years), producing U and U respectively, this occurred to an almost negligible extent due to the shorter half-lives of these parents 
where is uranium found and how abundant is it In nature and in and a very small amounts. how does it look? When refined, uranium is a silvery white, weakly radioactive metal. what military uses does it have? The major application of uranium in the military sector is in high-density penetrators. and civilian? The main use of uranium in the civilian sector is to fuel nuclear power plants. is it radioactive? Yes who discovered it? Martin Heinrich Klaproth. what kind of research is being done on it? Fission research. can it be used to make weapons? Yes. Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device whose fissile material was highly enriched uranium.
