Apr 12, 2007 · Fusion, which occurs when atomic nuclei combine to form new elements, is extremely powerful. All the stars in the universe, including the Sun, are nuclear.
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons. The first nuclei were formed about three.

Once upon a time, about 11 million years ago, in a galaxy not so far away (the LMC), the progenitor star of supernova 1987a was born, Sanduleak -69° 202 with a mass. Nucleosynthesis in the News: May 8, 2012: New insight into atomic nuclei may explain how supernovas formed elements crucial to humankind-- Science Daily The cognitive paradox that renders the obscured observation for the structure of atom, could thus be meticulously resolved with its underlying.
Our observations reveal a particular cloud produced by a supernova explosion 10,000 years ago contains enough dust to make 7,000 Earths," Ryan Lau of Cornell. A supernova is when a huge star explodes. It usually happens when its nuclear fusion cannot hold the core against its own gravity. The core collapses, and explodes.
