Should We Expect Other Earth-like Planets at All?
This year has been a spectacular one for exoplanets. New discoveries and new insights have truly pushed the gateway to other worlds even further open. In the past 12 months weâ€™ve gained increasingly good statistics on the incredible abundance of planets around other stars and their multiplicity. We also finally seem to have evidence that our neighboring star Alpha Centauri B does indeed harbor at least one world. It is by any set of standards, a great haul.
But I continue to be a bugged by the claims of â€˜habitableâ€™ worlds and â€˜Earth-like planetsâ€™ that seem to beset many scientific announcements. In the spirit of closing out the passage of our 4,500,000,000 th or so orbit around the Sun I thought Iâ€™d try to set the record straight, because I think we have so much more to look forward to than simply finding â€˜another Earthâ€™.
