NASA's Kepler mission has discovered a new batch of verified exoplanets, including nine that are potentially habitable:
NASA's Kepler mission has verified 1,284 new planets – the single largest finding of planets to date. "This announcement more than doubles the number of confirmed planets from Kepler," said Ellen Stofan, chief scientist at NASA Headquarters in Washington. "This gives us hope that somewhere out there, around a star much like ours, we can eventually discover another Earth."
Analysis was performed on the Kepler space telescope's July 2015 planet candidate catalog, which identified 4,302 potential planets. For 1,284 of the candidates, the probability of being a planet is greater than 99 percent – the minimum required to earn the status of "planet." An additional 1,327 candidates are more likely than not to be actual planets, but they do not meet the 99 percent threshold and will require additional study. The remaining 707 are more likely to be some other astrophysical phenomena. This analysis also validated 984 candidates previously verified by other techniques.
[...] In the newly-validated batch of planets, nearly 550 could be rocky planets like Earth, based on their size. Nine of these orbit in their sun's habitable zone, which is the distance from a star where orbiting planets can have surface temperatures that allow liquid water to pool. With the addition of these nine, 21 exoplanets now are known to be members of this exclusive group.

And all the necessary energy may be just here [wikipedia.org] (search for Alcubierre Drive) - no Jupiter destruction necessary.
Of course, it will create a certain signature and aliens will show up to invite us into the community...

How will energy be had from the Casimir effect?
And how to change the energy density of vacuum?

It was intended as a partial joke and I am not qualified for the "scientific" discussion.
However, the basis for it was that energy in theory is z(-3) which is 120 orders of magnitude more than what is observed. Once they used analytic continuation though, they got results that agree with the experiments. Now speculations are that perhaps energy is z(-3) after all and what we observe is a projection from some higher dimension universe. Hence my "proposal" to pump it from over there exactly like in Ian Banks novels. Anyway, that's how it was described to me by some adepts over a few drinks)

How does one even get the ability to affect anything like this? or even pump it?
