how far light travels in one year

A star 5x the size of our Sun will become:

a red supergiant, then a supernova, then a black hole

The Big Bang Theory is supported by:

Cosmic Background microwave radiation

why stars further away appear to move less in the sky

The number of kilometres travelled in one light year is:

The number of light years x 300,000 x 365 x 24 x 60 x 60

An astronomical unit is:

the distance from the Earth to the Sun

astronauts need to make sure they don't get sunburnt
