The sun will not implode. It will eventually explode in a spectacular event called a red giant phase and then a planetary nebula before finally becoming a white dwarf.

Here's the breakdown:

* Red Giant Phase: In about 5 billion years, the sun will run out of hydrogen fuel in its core. This will cause the core to contract and heat up, leading to the expansion of the outer layers. The sun will swell to become a red giant, engulfing Mercury, Venus, and possibly Earth.

* Planetary Nebula: After the red giant phase, the sun will shed its outer layers, creating a beautiful shell of gas and dust called a planetary nebula.

* White Dwarf: The remaining core of the sun will be a dense, hot object called a white dwarf. It will slowly cool and fade over billions of years.

Implosion is typically associated with stars much larger than our sun. These massive stars can collapse under their own gravity, leading to a supernova explosion. However, the sun is not massive enough for this to happen.
