"Astronomers have confirmed the existence of an Earth-like planet in the "habitable zone" around a star not unlike our own.
The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C.
It is the closest confirmed planet yet to one like ours - an "Earth 2.0".
Kepler 22-b lies at a distance from its sun about 15% less than the distance from the Earth to the Sun, and its year takes about 290 days. However, its sun puts out about 25% less light, keeping the planet at its balmy temperature that would support the existence of liquid water.
.................
I wonder where most astronomical telescopes are pointing now? 😀

Near future, nill, zip nada.
Far future.... maybe, depends which, if any, of our GUT's are right and whether they include the
possibility of practical FTL travel.
More likely perhaps is a combination of atomic rocket technology and transhumanism where we use
relativistic rockets plus A-humans adapted to living in space with extremely extended (biologically immortal)
lifespans. In which case travelling around the galaxy becomes possible.
However none of this is likely to be soon.

Ion rockets are BS. Nano-rockets aren't a far cry from becoming a reality.
We aren't quite able to minimalise and quantify/control human thought on the quantum level yet, but it may be on the cards one day, to enable non-physical far distance travel ITNF simoultaneously, that being maybe 2 centuries. 😀

I have no idea what it is you just said.
Please assume you are talking to people without your Magic, UFO, Theist, New age, decoder ring,
and try explaining what you mean in plain English.
For starters Ion drive works rather nicely and has been used quite effectively. (This is in the reality
we inhabit, no idea what's going on in the one you proclaim to exist in)

You may want to look up Poe's law.

I mean, come on googlefudge, what does the rationale of the second post have with any regard, or any relevance, to an earth twin found? It was utter ignoramus in reference to the topic. 🙁
Post rubbish - receive rubbish, that's my motto for this time being. 😉

Yeah but Mars is in the 'habitable' zone and so is venus. One is too small and has too thin an atmosphere and the other has a runaway greenhouse effect.
We need to know its mass and its atmospheric composition before we say that it is "Earth's twin".

But still, you're right, it's a little premature to call it earth's twin.
