The surface was young and volatile as molten rock covered a globe utterly void of life. In these incredibly far-off times, the inner solar system was a violent and crowded place during which the Earth was repeatedly pelted with rocks from outer space. Some 200 million years after a molecular cloud of hydrogen and helium came together to form the Sun, the primordial Earth formed from some of the heavier elements that made up the protoplanetary disk left behind.īound by gravity, the leftover stardust from the Sun’s creation also formed the rest of the planets in our solar system. We now know from radiometric dating that the Earth is relatively young at only 4.54-billion years. That our planet exists is a truly remarkable feat of evolution, a journey that began 14-billion years ago when the Universe was born with the Big Bang.

This week, we’ll be exploring the Hadean aeon, named so after the Greek god of the Underworld. In the first article of a series entitled ‘A Journey through the History of Earth’, we’ll be taking a look at the violent birth of our world, a time of fire and destruction out of which came the first building blocks of life. The Earth during the Late Heavy Bombardment was a truly formidable place.
