Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

New insight into the behaviour of atomic nuclei may explain how gigantic star explosions, or supernovas, have formed the elements that are crucial to humankind. Ground-breaking research in nuclear ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...

Most of the carbon and nitrogen in our bodies probably came from a planet the size of Mars crashing into Earth 4.4 billion years ago, scientists say. Researchers have long thought that these elements, ...
