Some good news has come out of NASA this week, where scientists are able to determine the molecules found in the atmospheres of some known exoplanets (worlds outside our own solar system).
This is great news for any young scientists planning on creating an incredibly fast satellite that might be sent off to another solar system in search of habitable worlds. If we can determine the chemical compositions of atmospheres from light years away, then we can be sure to aim highly advanced space probes in the right direction.
I am consistently impressed by the incredible genius of the people at NASA and observatories around the globe. Only a few years ago people would have laughed when someone theorized that planets might exist outside of our solar system. Now we know of 182 that circle nearby stars. If we can determine the likelyhood of habitable worlds, then we can begin to work on the machines that would let us study these worlds for both life, as well as their viability as a colony site.
That is, of course, assuming that the world in question doesn't already have a sentient species in place.
I believe that we will find sentient life out in the cosmos. Hopefully they will be just as curious about us as we are of them. And hopefully we will have learned from our past mistakes with indigenous peoples of this world, before making the same mistakes somewhere in the expanse of space.
