um... the lifespan of the sun is 12 billion years, we are about half way to the 12 billion mark. (a little less). I think about 4.2 billion years old. The sun will engulf Mercury and venus in the last 2 billion years of its life span, then it will either burn out or explode. If it has a higher mass, then it would explode then turn into a black hole! whopee...
Hydrogen is turned into helium in the fusion process that releases the Sun's energy.
Fusion is the process by which the sun produces energy. In the sun's core, hydrogen atoms fuse together to form helium, releasing large amounts of energy in the form of heat and light in the process. This continuous fusion reaction is what powers the sun and allows it to shine.
The sun's energy comes from a process called nuclear fusion. In the sun's core, hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the process. This is what powers the sun and provides energy to sustain life on Earth.

Nuclear fusion, hydrogen burns and the energy gets turned into mass
Nuclear fusion. Stellar fusion in volves a number of different fusion reactions throughout the star's life, but the primary and (usually) the longest burning is the fusion of hydrogen into helium. This consumes most of the nuclear energy in the sun, and it usually accounts for the type of fusion that goes on for most of the life of the star. A link is provided to the Wikipedia article on the proton-proton chain, which is the "technical term" for hydrogen fusion into helium.
The process responsible for the enormous energy in the Sun is nuclear fusion. In the core of the Sun, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. This energy is what powers the Sun and sustains life on Earth.
In the core of the Sun, hydrogen atoms fuse to form helium in a process known as hydrogen fusion. This is the primary fusion process occurring in the Sun. As the core hydrogen is depleted, helium fusion into heavier elements like carbon and oxygen will occur in later stages of the Sun's evolution.
They are the same.
Nuclear fusion is the process that powers stars, such as our sun.
The fusion of hydrogen nuclei in the sun produces helium, along with energy in the form of light and heat. This process is known as nuclear fusion and is the source of the sun's energy.
