The Sun will not explode.

In about 4.5 billion years, our Sun will slowly cool and turn into a red giant, it's outer envelope will almost touch the Earth.

After about another million years, it will shed it's outer envelope, causing a planetary nebula What is left of our Sun, is a white dwarf about the size of the Earth, which will slowly radiate it's remaining heat into space for billion and billions of years.
