Earth-Like Habitable Worlds

Astronomers have just discovered three habitable Earth-sized worlds in the ‘Goldilocks’ zone of a nearby star, called “Trappist-1”, located just 40-light-years away. This star is much cooler and more reddish in color than our sun, while being barely larger than Jupiter in the constellation of Aquarius. “The planets are 20 to 100 times closer to their star than Earth is to the sun. This is more similar in scale to the system of Jupiter’s moons than the solar system,” said Michael Gillon of the University of Liege, Belgium.

“The team used a modest 60cm telescope, based in Chile, to find the planets. The astronomers believe all three may be habitable, and they are now turning larger instruments on these new worlds to find out more. While other exoplanet searches have concentrated on bright stars, Gillon and his team set up the Trappist survey specifically to scan the 60 nearest dwarf stars,” reports The Daily Mail.
