Three of these planets lie in the habitable zone, and as they Iraqi, they are likely to have liquid water on them.

These exoplanets could be a significant target to look for alien life.

The started flood Trappist one, which is a small loan last call dwarf star.

Located 40 light years away in the constellation Aquarius.

Its radius is only 11% of that of our sun, making it around the same size as Jupiter.

The seven planets orbiting the star currently just named B, C, D, E, F, G and H.

They're all thought to be rocky.

So could potentially hold liquid water, which is the Peter sustaining life.

Andi, as a result, is what makes the McCue tog in our search for extraterrestrial life.

They're extremely close together in the orbit of the star and all that orbits would fit inside of our son.

They're close enough together that you could look up on one of the planets and see the rest of them sitting in the sky, similar to how the moon looks to us.

The length of their years ranges from 1.5 days to 20 days, and all of them have a side constantly facing the sun.

So one side is always bathed in son and the other in darkness.

NASA launching the James Webb telescope in 2018 which could further our knowledge of these planets by looking out for the chemical signatures of water, methane and oxygen on any of the planets.

This discovery hints that there may be more similar plants to earth in the universe than astronomers previously thought, given the prospect of alien life more promise than ever before.

If you like this video, I would like to see more about spokesman some pain.
