Pretty awesome discovery. Now we have a good "close" target to start building and testing some of the proposed interstellar propulsion methods.
That assumes the planet is even habitable.
There's every chance it's more like Venus than Earth.
Such things are just fairy tales for now. It's still a hardcore challenge to get to a much closer and proven to be decent planet: Mars. And even if we get there, we still don't really have a clue what to do with it, at least if you leave the fairy tales aside. As vital as space travel and expansion is for the survival of our species, to be honest I don't think we'll make it in time. We're still at the level of dreaming about mining nearby asteroids and processing the raw ore in orbit, mostly with robots. Transporting human beings in safe conditions over such distances, with the equipment needed to survive the journey and establish a home elsewhere, that's just blue sky dreaming.Quote:

I call dibs.
I was thinking of just a Voyager-like probe to 1) test the feasibility and potential unknown issues with interstellar flight, and 2) should it get there, to get a closer look at the planet. Transporting people comes after we know more about how to get to another star. Proxima b is just the first reasonable target for such an effort. And dreams are the seeds of future reality.Quote:

This is one of the many reasons why I can't be that overly excited about the discovery of a seemingly nice planet several light years away. There's a decent one right next door that is yet way out of reach.
Very true wooly, but unfortunately, Mars hasn't ignited our imagination (or doesn't anymore). However, perhaps Proxima b might just do that - and Mars is a good first step towards b with regards to humans getting out of the Earth-Moon system.
Also consider that at the rate we're ruining this planet, we better reach a new one soon... :sweatdrop:
It ain't that bad and getting better, in London Museum you can find and iconic protest-letter that was written with water from the Thames instead of inkt.
Well, in Europe and North America it's getting better, but no so much elsewhere (look up the state of Chinese rivers, the Niger river delta, etc).Quote:

To quote one of my favorite singing philosophers, Eric Idle:
"And pray that there's intelligent life, somewhere up in space...cause there's 'bugger-all' down here on Earth."
