TRAPPIST-1 is older than our solar system


     NASA had made wonderful discovery of Trappist-1 system which is the best discovery of Hubble Space Telescope and NASA. Now, if we want to know more about the existence of life beyond the solar system, we need to know the age of the star. Young stars have frequent releases of high energy radiation called flares that can zap their planets. If a new planet is born then the orbit of that planet would be unstable.On the other hand, planets orbiting older stars have survived the spate of youthful flares, but have also been exposed to the ravages of stellar radiation for a longer period.

Now NASA's Scientists have a good estimate for the age of one of the most intriguing planetary systems discovered to the date called Trappist-1 System. A system of 7 earth seized planet orbiting a star which is nearly 40 million light years away from the earth. Researchers said that new study reveals that the star is too old between 5.4 to 9.8 billion years ago.

The seven wonders of TRAPPIST-1 were discovered using Transisting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, Spitzer Space Telescope of NASA, and other ground based telescopes.

Trappist-1 is 13.7 billion years old in age than the universe and it is like a slow-burning candle that will shine for about 900 times longer than the current age of the universe.
