In the beginning, the Universe was extremely hot and dense, but over time it began to cool and expand. Space filled with protons, neutrons and electrons, which are the building blocks of atoms. Over hundreds of thousands of years, stable atoms of hydrogen and helium evolved. These atoms then massed together in clouds called nebulae.
