Just wanted to point a thing out Jon: Relativistic Mechanics comes in handy at times! "20 light years from us" means that an electromagnetic signal sent from "here" and "now" would get there in 20 years according to our space and time. If we were able to travel at, let's say, 80% the speed of light (totally impossible at the moment...), time, for us travelling, would pass 40% slower than earth's time. This means that we'll be there in "just" 15 years of travel!

The thumbnail says "Earth^2" but, you said "Earth2". Shouldn't it be Earth Squared?

well it's a great news but 20 light year it feels like reproduction should be carried out in the space ship itself
and on Gliese 581g, theres a Gliese 581g Jonathon Paula who made a video about him talking about this new planet his people discovered called "Gliese 581g2" or Earth
