Since the exponential development in the space science and technology from the early 1960s, one question is hovering in the mind of most of the people, 'are we alone in the universe?'. Well, in order to solve this one question NASA has launched several missions since the 1990s. Recently, NASA had launched a new mission to find exoplanets and it looks like NASA have found it. About 39 light years away NASA has found a habitable temperature zone where seven exoplanets are orbiting around one star.

According to researchers, there are about six planets in the sister solar system have the similar mass to the earth. At the same time, the researchers have also found that the surface temperature of those planets is close to 0C-100C which can be suitable to many from of life. Scientists are also expecting that there is a possibility to find warm water in these planets.

There was a huge hype when NASA announced about the mission regarding extraterrestrial life and today NASA have triggered that hype by announcing it as a great discovery beyond the solar system. 

The exoplanets which were discovered is orbiting around an ultra cool smaller star called TRAPPIST-1. The location of this star is around 39 light-years away from our Sun.

Along with NASA, Belgium has also contributed fairly in this project. The team of the astronomers is led by Michael Gillon from the University of Belgium. Belgium has helped to find the first three exoplanets, therefore it can be said that it has helped the NASA a lot.

Though so far it seems like the exoplanets are much similar to our earth. But there are a lot of researchers to happen especially on the outermost seventh exoplanet. The system is really compact as the closest planet of the system takes 1.5 days to orbit around the star and the outermost planet takes just 13 days.
Therefore, there is a good chance that we will be able to research about all of these exoplanets and it won't take much time.
