To search for life beyond Earth, we first have to decide on several key factors, such as where we should look. Several locations within our solar system have been identified that might be habitable. An ideal place to look might be the icy moons around Saturn and Jupiter with their liquid oceans. However, once we decide where to look for life we then need to determine what we will look for and how we will look for it. If there is life in this solar system, other than on Earth, it seems most likely that it will be in the form of microbes. But what if it doesnt look like life on Earth – how will we know when we find it?
