In 1992 scientists confirmed for the first time that there were planets around other stars.
Think about that for a second. During all human history, it wasn’t until 25 years ago that we knew that there were other plants then our own. 25 years ago, we got confirmation that the galaxy contains billions of possible worlds. The idea that there are extra solar worlds to visit moved from science fiction to fact just 25 years ago.
Since then, with the launch of new instruments, we’ve been finding thousands of new plants. Some of them are in the Goldilocks zone, (Not too hot, not too cold) where water could exist on the surface. That mean that life as we know it could exits on these plants. It also means that if the atmosphere is correct, humans could walk around without a space suit. The implications of that alone, is amazing. There could be millions of Earth like planets out there, all with the possibility of life.
That brings us to this week’s announcement about Trappist-1. It’s a a tiny dwarf star with 7 rocky planets. Three of those planets are inside the habitable zone. Our solar system only has 4 rocky plants, so right away this system has more surface, more minerals and resources than we do. It also has three plants that could potentially harbor life, or be habitable for humans.
This sort of stuff blows my mind. Look at Earth compared to these planets, and imagine all the war that goes on over land and resources on its surface. I think getting to Mars would be amazing, but just imagine what it would be like to travel to and live in this solar system. It has magnitudes more than we have, just waiting for us.
