A GIANT EXPLOSION BAM!!
After a supernova, a massive star collapses inward under the force of its own gravity, resulting in a catastrophic explosion. However, the Sun is not massive enough to undergo a supernova event.
The future fate of the Sun is different. In about 5 billion years, the Sun will exhaust its nuclear fuel and begin to transform into a red giant. During this phase, the Sun will expand and become much larger than its current size, engulfing the inner planets, including Earth.
After the red giant phase, the outer layers of the Sun will be expelled into space, forming a glowing shell of gas called a planetary nebula. The remaining core of the Sun, known as a white dwarf, will gradually cool down over billions of years, eventually becoming a cold, dark object known as a black dwarf.
To determine the fate of stars after a supernova event, scientists use stellar models and simulations that take into account factors such as mass, composition, and the mechanisms involved in stellar evolution.
