Astronomers Have Found A Solar System With Three Earth-Like Worlds

European astronomers have just detected something incredible! After observing the ultracool red dwarf star TRAPPIST-1, they detected three Earth-sized planets transiting it, all of which orbit the star closely enough to be habitable.

Using the Belgian TRAPPIST telescope, they detected the signatures of three very small worlds by detecting their transit of the red dwarf star. The star is considered to be an “ultracool” dwarf star. This means that it’s in between a red and brown dwarf star.

 
The big differences to our solar system (other than 3 earth like planets) is that the mass of the star is only 8% that of our Sun’s. About the size of Jupiter’s. It will be interesting to see how a small star like that affects planets near by.

The stars/planets can be found in the constellation Aquarius some 40 light years away. With the small size and weak luminosity, it will be important to study it as stars this size are the majority of all stars. Unlike our start, they have slow-burning interior engines meaning they’ll live for a trillion years or more.

This means that the planets of such stars could be habitable/have been habitable for a looooong time. Could that mean that there is some alien species out there that’s the age of the universe!? With earth only being a few billion years old, we are a very very young planet.
