Written to be easy to read and understand, The Living Universe explores how the latest scientific discoveries are rewriting what we thought we knew about space, planets, and the origins of life. We now know that the universe is filled with planets, not just around other stars but also traveling in the space between them, and that many of these carry life with them. Some of these wandering planets have almost certainly been captured by the Sun's gravity, changing not just the arrangement of planets in the Solar System, but also the development of life on our Earth.
