Australian astronomers are searching for planets in other solar system that could sustain human life. Dr Charley Linweaver says Mankind is reaching the beginning of the end. It's time to look for a way out at least for a small group of people. The number of planets identified orbiting other suns now exceeds 750. Though a few of these could be like the Earth, exact information is lacking.
The objective of getting people to such a distant destination is way "off the planet" at present. We do not have the technology to get people in orbit around other planets in our own solar system, let alone reaching a far away planet and landing safely.
Finding an identical planet to Earth is just not possible. This planet is a freak in regard to the universe. Most planets do not have life because they are regularly hit by asteroids and even other planets. Sending probes to a possible twin planet would be a waste of time. It would literally take a lifetime to get a message back.
