JAKARTA There is nothing eternal in this universe, be it humans or the Earth they live in. In fact, the Sun that has been crossed by Earth for billions of years can die and be destroyed in the end.
If you don't know yet, the Sun is a star. This astronomical object is shaped like a giant hydrogen ball, but with a very hot energy source. With the amount of energy released by the Sun, how long will this star last?
No one knows for sure, but scientists believe the Sun will out someday. This is due to the creation of energy that continues to drain the energy of these astronomical objects.
According to NASA's explanation, the Sun can shine brightly because gravity suppresses it. This gravity drives the Sun to create energy and use the whole hydrogen produced.
During this process, the Sun also creates helium and uses it as well. This process will continue to repeat itself until the Sun uses larger elements, continues to grow bigger until its elements cannot be used anymore.
"When that happens, it will begin to expand into a red giant the size of the inner planet. Then, it will shrink back into a very strange star called a white dwarf, very hot, but not very bright," NASA explained.
This white dwarf is expected to be the size of the Earth. However, there is also the possibility that the sun will never go out. Even though it is not extinguished, the Sun will certainly dim or be different from its normal activities.
"However, our Sun has a long life. The sun has reached half of its life span of 10 billion years," NASA said.
