Will The Sun Ever Stop Shining?
Scientists tell us that after about five billion years the sun will begin to die, just as all stars do. First, the sun will get hotter. Then it will probably swell up. Slowly it will become much, much bigger. As it grows bigger, its colour will change from yellow to red. As it grows bigger, it will pour out more heat. The earth will become so hot that all the rivers, ponds, lakes and oceans will boil and turn into steam. All plants and animals will die.
After about a billion more ears, the sun will start shrinking. It will become smaller and smaller, the colour will change from red to white. Its brightness will fade. It will become cooler and smaller, and finally be a dead, black ball, a little smaller than the earth. When the heat given by the sun starts reducing, the clouds of steam around earth will turn back into water and fall as rain. Oceans and lakes will fill up again. But as the sun grows cooler, earth will also grow colder. All the water will freeze. Earth will become a lifeless ball of rock and ice-cold, dark and silent.
