NASA has just dropped a big bombshell with their newest discovery. They have identified a solar system just 39 light years away that contains seven Earthlike planets.

We have found a few Earthy planets in the past, so what makes this discovery so important? This is the highest number of these types of planets that we have ever found in a single solar system. Not only does this discovery effect how scientists perceive the possibility of numerous other similar planets, but this is also our best chance at finding other life forms from foreign planets.

Before this discovery if scientists wanted to look at terrestrial planets they needed to look at the four within our own solar system. Now, there are an additional seven planets for us to look at that are in an entirely different system. There is the possibility that we could find water else ware in the galaxy, but even if these planets don’t contain water or life they will be a very interesting discovery.

This new solar system is basically a smaller version of our own. The star at the center of the solar system is a cooled dwarf star that has been named TRAPPIST-1. It is about the tenth of the size of our own sun and is only a fourth as warm as ours. The planets are fairly close to the star with the closest one taking a day and a half to rotate around it, and the furthest taking only 20 days to rotate. Had this star been warmer or larger it is likely that these planets would have been burned up, but the size of the star is perfect for sustaining life and water. They are considered to be in the “habitable zone”.

Of course there is a lot more needed in order to sustain life, and we’ll find out if these planets meet the marks over time as we look further into this solar system. We will need to see what the planets are made of, if they hold an atmosphere, if they contain water, and other important elements such as oxygen and carbon dioxide.
