Recently, on September 29th 2010, a new Goldilocks planet was (41) ____discovered_____ by scientists using one of the most (42) __________ telescopes on Earth – the Keck telescope in Hawaii. Gliese 581g lies 20 light years away from its star’s ‘Goldilocks zone’ – an area (43) _________ temperatures are favourable and planets may be (44) _________of containing water, and therefore also life. This planet might be the most similar “Goldilocks planet” to Earth yet discovered. “The fact that we were able to detect this planet so (45) __________ and so nearby tells us that planets like this must be really common,” says Steven Vogt an astronomer at the University of California Santa Cruz. The planet’s (46) __________ temperature is thought to be between -12C and -31C, and we know for a fact that there are many intelligent animals living in these types of (47) ___________ on Earth, such as polar bears, whales, and even humans, such as the Inuit peoples. Dr. Vogt goes on to state that: “The number of systems with (48) ________ habitable planets is probably in the order of 10 or 20%, and when you multiply that (49) __________ the hundreds of billions of stars in the Milky Way, that’s a large number. There could be tens of billions of these systems in our (50) __________.” Tens of billions of planets. This is a huge number! Surely we cannot be so nervous to think that we are The star Gliese 581.
