Star dust

As I was walking through Holyrood Park this morning, it was still dark o'clock. As it was a clear morning, in the sky I saw the stars rising above Arthur's Seat and thought wow.

Around 4.5 billion years ago, a star began forming from a cloud of dust, which had been formed from the death of another star. As the star formed, and gravity started to act, the dust cloud swirled around this new star, condensed and formed the planets around that star, bringing our solar system into being. So I and all people are made from star dust. Now, that's pretty cool.
