After our sun's core hydrogen is exhausted

The Sun does not have enough mass to explode as a supernova. Instead it will exit the main sequence in approximately 5 billion years and start to turn into a red giant. As a red giant, the Sun will grow so large that it will engulf Mercury, Venus, and probably EarTh.

Planetary Nebula: Gas and Dust, and No Planets Involved

In about 5 billion years, when the sun shucks off its outer layers, it will create a beautiful shell of diffuse gas known as a PLaneTary NebuLa. About 10,000 of these short-lived, glowing objects are estimated to exist in the Milky Way, although only about 1,500 have been detected; the unseen rest hide behind interstellar dust.
