Nuclear fusion happens when lighter elements, like hydrogen, are combined into heavier elements, like helium. In about 5 billion years, the hydrogen in the Sun’s core will run out and the sun will not have enough fuel for nuclear fusion. So, in about 5 billion years, the Sun will stop shining.
The Sun is expected to keep shining for billions of years more. It is currently in the main sequence phase of its life cycle, where it fuses hydrogen into helium in its core, generating energy in the process. This nuclear fusion process has been going on for about 4.6 billion years and is expected to continue for another 5 billion years or so. Eventually, the Sun will exhaust its hydrogen fuel and begin to evolve into a red giant, swelling in size and engulfing the inner planets, including Earth, before eventually cooling and fading away. But this process is expected to take billions of years, so there is no need to worry about the Sun’s light going out anytime soon.
