Making the Sun
The Universe is made up of countless clouds of gas and dust. Around 5 billion years ago. one of this swirling clouds formed a miiling - sized star - our Sun. The energy released by its burning gas provides the light and warmth necessary for life on Earth.

What makes the Sun shine?
Light from the Sun radiates through the entire Solar System. This light is generated in the core of the Sun, where temperatures reach around 15 million degree (27 million Fahrenheit), as hydrogen gas is converted into another gas, called helium, in a series of thermonuclear explosions, billion of times more powerful than the biggest nuclear bombs, are mere pinhead of these gases would be hot enough to ignite everything for 100 km (60 miles) around. The hot gases churn slowly towards the Sun's surface, where the burning solar gas shine for millions of miles into space.
