A star system with three Earth-like exoplanets discovered by NASA's Kepler Space Telescope could advance the study of the atmospheres of alien worlds similar to our planet and provide evidence of alien life.

The outermost of these three planets planet orbits inside the "Goldilocks" zone, which is a region that possesses moderate temperatures conducive for liquid water to form and that could lead to the creation of microbial life.

This star system called EPIC 201367065 is about 150 light years away from Earth. Its sun is a cool red M-dwarf star half the size and mass of our Sun.

This red dwarf star is among the top 10 nearest stars that have transiting planets. This means the star's proximity from our solar system makes it possible for astronomers to study their planets' atmospheres to determine if they have Earth-like qualities conducive for life.

According to Erik Petigura from the University of California Berkeley, the three planets have diameters roughly the size of Earth. The outermost planet is about 1.5 times the diameter of Earth. This outermost planet could possibly sustain life since it receives enough sunlight from its host star.

Exoplanets and extrasolar planets are now discovered by the hundreds although it's still unclear to scientists if these new found worlds are similar to Earth, said astronomer Andrew Howard from the University of Hawaii. This new planetary system could help resolve this enigma.
