Our questions and the answers we found
Why is the Sun hot?
Nuclear reactions are constantly taking place in the Sun’s core, generating huge amounts of heat and light energy. The temperature at the surface (the corona) is even hotter than the core, at 2 million degrees centigrade, although scientists don’t yet understand why.
Why do people float in space?
Because they are outside the gravitational pull of the planets.
How far is it to space?
Why is it always dark in space?
The light from a star travels outward in all directions. Any object, such as a planet, that gets in its way will be illuminated. Otherwise, the light continues to travel

Here are some other facts that we discovered at the Space Centre:
