The discovery of the 7 earth like planets orbiting around the TRAPPIST-1 dwarf star has given human kind a lot of hope that there really could be life closer to earth than previously imagined. With this, it is also now a question of whether more dwarf stars might have such earth like planets.
As one of the scientists involved with the discovery of the TRAPPIST planets puts it, this is a major advancement in figuring out life elsewhere. Life is adamant and it finds ways to exist even in the harshest of conditions. With the right setting, life can exist, the only question therefore is – what kind of life can we expect?
Before even going into prophesizing the kind of life to expect on these planets, it would be nice to think of what they would have to undergo. For instance, because of the dimness of the stars, will the daytime skies be darker than that of Earth? Will the air remain warm though because the light from TRAPPIST-1 is mostly infrared and not much in the visible spectrum? Will there be a reddish glow across the planet with almost everything having a red color?
One thing is for sure that looking up into the sky will be a pleasant experience. You would not just see the sun but also several planets dispersed around. Some twice as large as Earth’s moon and others slightly smaller. It all came down to which planet you were on. Only through more research and spotting of similar systems can these answers be finalized.
What really excites astronomers though is that around 15 percent of all our neighboring stars happen to be cool stars like the TRAPPIST-1, which provides nearly 600 possible targets for our future researchers to gaze at.
