Out of This World: The Amazing Search for an Alien Earth

When I was born in 1964 we knew of nine planets in the entire universe, those from Mercury out to Pluto. When anyone looked into the inky night sky, they could see millions of stars, but we didn’t know if these distant suns shone on alien worlds. Now we do. In 1995 astronomers discovered the first exoplanet – a planet around a star other than the Sun. To date we’ve found more than 400, all of which are large, Jupiter-like gas planets.
Now the search is on to discover the first, rocky Earth-like planet – an alien Earth. It’s one of the greatest quests in human history, and readers of Out of This World belong to the generation that will be transformed by a new view of the cosmos.

I was initially asked to write a book about UFOs and crop circles. I said: The real story of the search for alien life is way more interesting! Today, astrobiologists aren’t searching just for aliens in spaceships, but entire living planets.
Out of This World tells this amazing story.
