Trappist-1 Exoplanets Could Hold Life

Bizarre giant planet with three stars discovered

Finding life in other planets is what astronomers are now finding out. The hunt for alien life has not shown much evidence so far. However, astronomers are hoping that Trappist-1 exoplanets could hold life.

A new solar system has just been found that could possibly have life. The star system has a habitable zone that could possibly sustain life in it. What is notable with the star system is that it has seven planets, and out of those seven planets three could have the possibility to have life.

Another notable feature of the star system is that the planets found are all Earth sized. Evidence of life in the star system could then be just a matter of time. Astronomer Chris Copperwheat from Liverpool John Moores University has said that the discovered planets could be good candidates for the search for life.

The star system has Trappist-1 as the central star there. The star is said to be still young, so chances of life forming on the planets there are high. Trappist-1 can live so long since it burns hydrogen at a slow rate, as explained by Ignas A.G. Snellen from Leiden Observatory.

Trappist-1 has been discovered in 2010, according to The Independent. Astronomers have been observing the star for signs of a transit, or an object that passes in front of the star that it would dim the star momentarily. In this way astronomers can now if an object is with the star and how big it could be.

Astronomers are now working to see what could be the composition of the planets there, as The Telegraph reports. Although they could have an estimate of its size, direct observation would still not be possible. The star system has so far amazed astronomers because it has planets that all have the same size as the Earth.

There would be less light on the planets though, as Trappist-1 is a dwarf star. That means it is smaller than the Sun, so less light would be received by the planets around it. Life on the planets there could possibly be different from what is found on Earth. Astronomers are still hopeful Trappist-1 likely could hold life. A study has found that comet Chuvy has dunes on it.
