Proxima Centauri Has a Terrestrial Planet
There was a time in living memory when we still had doubts that other stars could harbor planets.

Quote:An Earth-sized planet that could boast water, even an ocean, has been found circling the star nearest our sun, hinting that the conditions for life could exist next door.

Researchers have identified a plethora of planets outside our solar system that both resemble Earth in size and dwell in the “habitable zone,” where liquid water is possible. But no other Earth-like planet outside our solar system is as close to humans and their observatories as this new world, making it the best possible hunting ground for living organisms.

The find, reported in a study published Wednesday in Nature, has scientists reaching for superlatives.

“An absolutely amazing discovery,” says Victoria Meadows of the University of Washington. “This will be the most accessible, closest planet in the habitable zone to our solar system.”

Only about a thousand years from here using currently available technology. Who's up for a road trip.

Interesting news, only skimmed the article but it seemed to say that water was a possibility only.

If they detect oxygen that should be a clincher for life, or some other oxy generating system we do not know about.

Still, lots of effort going to be pointed that way! Goodie.

Tomorrow is precious, don't ruin it by fouling up today.

"Humanity’s first chance to explore this nearby world may come from the recently announced Breakthrough Starshot initiative, which plans to build fleets of tiny laser-propelled interstellar probes in the coming decades. Travelling at 20% of the speed of light, they would take about 20 years to cover the 1.3 parsecs from Earth to Proxima Centauri." --- from my link. Big Grin

I hope I'm around long enough to see us get a probe to an exoplanet.

Now if someone would be kind enough to also invent an Alcubierre drive, we could be set.

Need to think of a witty signature.

Yea but the Starshot technology isn't available yet, and probably won't be for decades. If we can get it to work it could get centimeter square probes there quicker, but as far as I know the best type of propulsion system for this kind of thing we currently have access to is nuclear thermal.

At work.

Who's up for building an old "Boom! Boom!" Nuclear pulse Orion?

A million ton or so ship should have both the 'Oomph!' to get up and go plus the space to stretch out and relax on the way.

Tongue

Thumbsup

Edit: Also.... look up "Valkyrei" the actual hypothetical ship work which was thence depicted in 'Avatar' the movie.

Thumbsup

Seriously, this is awesome news. Exoplanets are cool, but if they're all too far away to even potentially reach in my lifetime... meh. But this changes everything; even if it's not habitable, it's worth exploring. Oh, what a thing to hear before I die, the first reports coming back from the arriving probe, the first images of a planet around another star.

If only Asimov and Heinlein could have lived to see that day.
