Comets May Have Provided Earth The Building Blocks Of Life
A team of scientists in the UK have discovered that when an icy comet collides with a rocky planet, or a rocky meteorite with an icy planet, the basic building blocks of life can be created. They say it explains the “jump-start” of life on Earth that occurred when our planet got bombarded with comets and meteorites some 4.5 to 3.8 billion years ago. The team recreated the impact of a comet by firing projectiles into typical cometary ice mixtures at high speeds from which amino acids, proteins critical for life, were formed. They say that similar events could occur or have likely occurred elsewhere in our Solar System.
