Exciting New Exoplanet Discovery

NASA announced this week that a new solar system comprising of seven Earth like planets has been discovered only about 40 light years from Earth. Named the TRAPPIST 1 system (after the Chilean telescope used to discover them), This system includes at least three planets that are considered to be within the 'Goldilocks Zone' that is "not too hot, not too cold, but just right!". The possibilities are that each of these three planets could be host to life as there is a strong likelihood of liquid water in existence.

While there are still many other factors that determine if life will exist there, the sizes and densities of the planets and their location relative to their star is an exciting possibility for astronomers and astro-biologists.
