New life might be waiting just around the corner, as a brand-new "super-Earth" was recently discovered by a team of astronomers from UC Santa Cruz and the Carnegie Institution for Science.
As PhysOrg.com reports, the planet is roughly 4.5 times larger than our own Earth and orbits host star GJ 667C, an M-class dwarf star in a triple-star system. Even more interesting is the fact that despite the abundance of suns, the planet is at a perfect distance from its host star, perhaps at just the right distance that people could live there. With that many suns in the planet's skyline each day, it's surprising that it can support life in the form of water -- but then again, even Tattooine manages moisture, and it's mostly a desert world.
Also, this super-Earth is relatively close to our own solar system, but definitely nowhere where we'll be able to reach any time soon. At 22 light years away (or 132 trillion miles of space, if our math is accurate), it would take even the fastest space probe roughly, well, forever to even get that far. We won't bore you with the equations, but by the time a probe reached "Earth 2" in time to ask them to come pick us up in their assumedly-advanced spaceships, the Earth's water and atmosphere would already be completely burned away by Sol, our own host star.
On a cheerier note, Geekosystem notes that the discovery of this planet means that there's probably a lot more hospitable worlds than we think. Whether or not that means there could be closer super-Earths is anyone's guess. If there are, we certainly hope something out there is willing to drop us some light-speed travel technology and let us couch surf for a while.
Look into it further if you happen to read Astrophysical Journal Letters, while the official manuscript will go online at http://arxiv.org/archive/astro-ph via Cornell University.
