Explore the vast universe from stars to atoms, uncovering the origins of our existence in space. Learn how tiny molecules and atoms shape our world and how we are all connected through cosmic elements.

Our story starts off with stars in space
One day many millions of years into the future
Ouch! it’s
There are lots and lots and lots of stars like our Sun in space
In fact there are about ten thousand million million million stars in Space
We can write this in numbers as 10 000 000 000 000 000 000 000
10 000 000 000 000 000 000 000 1 followed by 22 noughts (or zeros)
We can write 10 000 000 000 000 000 000 000 as 1022

Now lets think about something that is very Very small a molecule
Molecules are bundles of very tiny atoms Carbon atoms C Nitrogen atoms N Oxygen atoms O Hydrogen atoms H …mainly
The water molecule, H2O, has two Hydrogen atoms and one Oxygen atom O H H
and it is very very very small
In a glass of water there are about a million million million million water molecules
All your atoms were made a very long time ago inside a star a bit like our Sun
That star exploded millions of years ago
and ended up here TODAY
So we all came from outer space We are all aliens
We tried to create a bit of a very very hot star in our laboratory
