NASA announced concussion: 7 Earth-sized planets could have life

NASA has just announced the discovery of 7 planets of the same size and mass as the Earth and together in a single star system - the Trappist-1 star system 40 years away from us is probably the environment for Live can exist.

All 7 planets revolve around the cold dwarf Trappist-1 and are in a position where the temperature is not too harsh between 0 and 100 degrees Celsius. That is, if water exists on these planets, it will be liquid form and can maintain life. Scientists at NASA hope, Trappist-1 may be another star system in this vast universe that may exist life.

Among the 7 planets discovered, 3 were identified: TRAPPIST-1E, TRAPPIST-1F and TRAPPIST-1G.

Trappist-1E : has the same size and temperature as Earth.

Trappist-1E.

Tranppist-1F : It is about the same size as the Earth, even if there is a large ocean on this planet. The time it spins around the Trappist-1 star in the middle is 9 days and the amount of light this planet receives will be almost the same amount that Mars received from the Sun.

Tranppist-1F may have a large ocean.

Trappist-1G : This is the largest planet of Trappist-1, it is about 30% larger than the Earth and getting enough light to make a difference.

The distance of 40 light years is not the closest distance of Earth to the previously discovered life-like planets like the planet Proxima b, only 4.2 light-years away. And with this spacecraft technology, it takes millions of years for people to set foot there. But this finding is a great step forward for scientists to take a step forward to continue seeking the answer to the question: Can people be really lonely in this vast universe?
