NASA have just recently discovered more than 200 new planets and 10 of them are the right size and temperature to sustain life.
The distant worlds were discovered by the planet hunting Kepler telescope, which for four years of searching has discovered 49 planets that seem to be able to sustain life and are in the so-called “Goldilocks” zone.
This is the area around a star which is considered neither too hot, nor too cold, to sustain complex life.
Commenting on the discovery Kepler scientist Mario Perez said: “Are we alone? Maybe Kepler today has told us indirectly, although we need confirmation that we are probably not alone.”
Kepler has already found dozens of worlds of interest and has still only looked at a tiny part of the galaxy. It has searched just a quarter of 1% of a galaxy which holds around 200 billion stars.
Of the 10 new planets which could sustain life, NASA says seven of them circle stars which are not unlike the Sun.
The findings do not mean that the planets definitely have life, just that it has the basic requirements for life have been met.
In all, Kepler has discovered around 4,000 ‘candidate’ planets but only half of those have had their existence confirmed.
Along with other methods of discovery it means scientists are now confident that they have identified around 3,6000 exoplanets and around 60 of them could be habitable by humans or other lifeforms.
