I don't get the use of "into" here. It appears to have two different meanings: (1) It means "as a result" ( fuses four protons together, and as a result, you get a helium nucleus).
(2) It means "to join/to be added up to" (fout protons fused together to join a helium nucleus - the combination would have more than 4 protons).
Which is correct?

Neutrinos reveal final secret of Sun’s nuclear fusion
Detection of particles produced by the Sun’s core supports long-held theory about how our star is powered.
Physicists have filled in the last missing detail of how nuclear fusion powers the Sun, by catching neutrinos emanating from the star’s core.
The detection confirms decades-old theoretical predictions that some of the Sun’s energy is made by a chain of reactions involving carbon and nitrogen nuclei. This process fuses four protons together into a helium nucleus, releasing two neutrinos — the lightest known elementary particles of matter — as well as other subatomic particles and copious amounts of energy. This carbon-nitrogen (CN) reaction is not the Sun’s only fusion pathway — it produces less than 1% of the Sun’s energy — but it is thought to be the dominant energy source in larger stars.
