ARE WE NOT ALONE IN THE UNIVERSE ?




Hi guys, Camilla and Francesca here! We would like to post about the breaking news of the day, that is NASA discovery.

NASA has announced that life may have evolved on at least three planets in a newly discovered solar system just 39 light years from Earth. Astronomers have detected no less than seven Earth-sized worlds orbiting a cool dwarf star know as Trappist-1.
It is an ultracool dwarf star that is approximately eight per cent the mass of and eleven per cent the radius of our Sun. It has a temperature of 2550K and is at least 500 millions years old.
In comparison the Sun is about 4,6 billion years old and has a temperature 5778K.
These planets orbit at the right distance to possibly have liquid water somewhere on their surfaces and the temperature range from zero to 100C.

No other star system known contains such a large number of Earth-sized and probably rocky planets.
Isn’t that  truly fascinating news? Life in a different solar system means we may not be alone in the universe! Super exciting!
