Is there life in outer space?

Most people have wondered if there is life beyond Earth in space. With all of the countless billions of stars and possible planets and moons in space, many people think that under the right conditions, life can exist elsewhere in space. However, there is no evidence for this yet. NASA is operating or planning several missions which will search for evidence of life on Mars, on the moons of Jupiter and Saturn, and which will search for Earth-like planets around other stars. Other projects, like SETI, are scanning the sky for signals from intelligent life in outer space. One day these projects may discover life in outer space.
