As the sun continues to burn through its ingredients, it gets warmer every day and eventually our home becomes uninhabitable. The sun, which already has a surface temperature of 5,505 degrees Celsius and a core of up to 15 million degrees Celsius, burns with its ingredients. The sun is already incredibly large and contains 99.8 percent of the mass of the solar system. However, this mass is consumed, causing our host star to expand and give off more heat in a process called nuclear fusion.
In the sun, hydrogen atoms are compressed under enormous pressure and merge to release large amounts of energy in the form of heat.
As more hydrogen atoms merge, more heat is released and the sun grows while becoming lighter.
Eventually the sun becomes so big and hot that the earth becomes singed and uninhabitable.
Luckily, we still have a few billion years until this happens.
Science podcast Begins with a bang written in an article for Forbes: "When enough time passes, the changes in the sun will make the earth uninhabitable.
"Over time, the amount of mass lost by the sun will increase, especially as it enters the huge phase of its life. But even at this relatively constant velocity, the growth of helium at the core of the sun means we're warming up here on planet Earth.
"After about 1
"When the sun gets brighter, it involuntarily gets hotter and hotter.
"Our planet already has about three-quarters of the time when the earth is habitable.
"As the sun continues to lose ground, humanity and all life on Earth are nearing their inevitable fate."
