astrology? no.
nuclear fusion is joining atomic particles into one
creating that new heavier particles creates energy and releases electrons in the form of ions = energy

Fusion is when two atoms collide to form a new element which has the sum of all the protons of the two atoms which fused. Typically, in the sun two Hydrogen atoms collide to form one Helium.
Before a star is born their is a dense cloud of hydrogen atoms which are becoming more and more dense. As they become denser, pressure and heat begin to build. The result of which is the Hydrogen atoms are moving faster and faster. When two hydrogen atoms collide they have a perfectly elastic rebound. At some point the heat and pressure build up to where the hydrogen atoms are moving so fast they can no longer rebound from a collision. When this happens they fuse together to form helium. This process is called fusion and it releases an enormous amount of energy in the form of heat and light.

Fusion occurs when two atoms combine to form a new atom. It so happens that as this occurs, the mass of the new atom (so long as the new atom is not heavier than iron) is less than the mass of the two parent atoms. This difference in mass is released as energy.
Iron is the breakover point. Atoms heavier than iron require energy to be applied to the two that are fusing. So, under normal circumstances (if you can call 30 billion degrees and millions of kilograms per sq. cm. pressure as normal) no atom heavier than iron can form.
So, how ARE heavier atoms formed? They are formed during novae and supernovae explosions, where there is an excess of energy.

The joining together of atomic nuclei lighter than iron to form heavier atoms up until Iron, during this process, some mass is converted into energy, releasing a lot.

It is in wrong category.
It should be in nuclear physics.
Fusion is to combine, fission is to split.
