"This is a useful finding which demonstrates that colliding helium at the sorts of energy we would observe in solar winds, can generate molecular oxygen when it hits carbon dioxide," said Benoit.

Helium atoms are single atoms. The atoms of elements such as hydrogen, nitrogen and oxygen join in pairs to make molecules. Water is made of molecules. Each water molecule is made from two ...
