Dawns Awakening

The Sun is a star at the centre of the Solar System. All the planets revolve around it.


The Sun is a 1 million km wide ball of burning gas. So be prepared for the best firework show you have ever seen!


Solar flares

Variations in the Sun's magnetic field cause huge jets or loops of stellar material to shoot out into space.


Solar wind

Solar flares can be accompanied by dense clouds of electrically charged particles, travelling at around 450km per second. When they reach Earth, they can affect communications satellites.


But make sure you wear your protective sun filters over your eyes otherwise you could damage your eyesight.



The Sun is by far the brightest object in the sky. It's so bright that during the day its light drowns out virtually everything else in space.


The Sun is so powerful that even from the Earth, its light can damage your eyesight. So never look at the Sun directly or through a telescope.


The best time to appreciate the majesty of the Sun from the Earth is during a solar eclipse. Then the Moon passes in front of the Sun and so it temporarily disappears from the sky.


Life on Earth is totally dependent on the the energy it receives from the Sun. This energy is produced when hydrogen atoms inside the Sun fuse to form helium.


The Sun consumes four million tons of hydrogen every second. Even so, it's so vast that our star has enough fuel to keep it shining for another five billion years.


The Sun's energy output is estimated to be 386 billion, billion megawatts. So in 15 minutes our Sun radiates as much energy as mankind consumes in all forms, during an entire year.
