Great Review!

Once upon a time, there was a small cold cloud of gas and dust in an interstellar medium broken into several clumps and laments of di erent masses and dimensions. Then, about 4.5 billion years ago, the small cloud became the Solar System. What happened to that primordial cloud? When, why and how did it happen? Does the Earth receive a heritage from those old eons? Can this heritage help us to understand our origins?
