Tau Ceti's planets nearest around single, Sun-like star

The nearest single Sun-like star to the Earth hosts five planets - one of which is in the "habitable zone" where liquid water can exist, astronomers say.
Tau Ceti's planetary quintet - reported in an online paper (http://star-www.herts.ac.uk/%7Ehraj/tauceti/paper.pdf) that will appear in Astronomy and Astrophysics - was found in existing planet-hunting data.
The study's refined methods of sifting through data should help find even more far-flung worlds.
The star now joins Alpha Centauri as a nearby star known to host planets (http://www.bbc.co.uk/news/science-environment-19959531).
In both those cases, the planets were found not by spying them through a telescope but rather by measuring the subtle effects they have on their host stars' light.

An exoplanet is a planet that exists outside our Solar System
Most are giant planets believed to resemble Jupiter or Neptune
The first exoplanet was discovered in 1992, orbiting a pulsar (http://www.bbc.co.uk/science/space/universe/sights/pulsars)
A few years later, the planet 51 Pegasi B (http://www.bbc.co.uk/science/space/universe/key_places/51_pegasi) was found orbiting a star similar to the Sun
Hundreds of extrasolar planets have been found since

Where do I book a flight?

Few months ago i've heard that scientists found 400 earth like planets and amateurs from Planet Hunters (planethunters.org) found 30 or 40 rocky planets with safe distance from star


Where do I book a flight?

They will not take you to different planet but for sure a bit closer to one :P

Kepler Space Telescope Data Reveals Billions Of Earth-Like Planets Near Earth

If ET phones home today, his long distance charge might not be as much as people believed when Steven Spielberg's classic film came out three decades ago.

That's because recent data from NASA's Kepler space telescope suggests that billions of Earth-like planets are much closer than ever before imagined.

"The information we presented today will excite the general public because we now know that the nearest potentially Earth-like world is likely within 13 light years of the sun," astronomer Courtney Dressing said in an email to The Huffington Post.

"Astronomically speaking, 13 light years is practically next door."

While we don't know if intelligent life exists on any of these planets, it raises the chances of that possibility.

I don't want to use the D word but it seems like there is more information coming out daily that is setting the groundwork

And a way to get there

A few months ago, physicist Harold White stunned the aeronautics world when he announced that he and his team at NASA had begun work on the development of a faster-than-light warp drive. His proposed design, an ingenious re-imagining of an Alcubierre Drive, may eventually result in an engine that can transport a spacecraft to the nearest star in a matter of weeks — and all without violating Einstein's law of relativity. We contacted White at NASA and asked him to explain how this real life warp drive could actually work.

I have been discussing the speed of light with some Physicist's lately. I see light speed as nothing more then just the speed on a freeway, where some cars' go faster if they want to. The speed of light is only revelant to the observer at one stationary point. Let's say this new found planet is moving away from us and i point a flashlight at it. And i know, a flashlight is only an example for light speed. To the folks on this new planet, they would see it moving much slower as it shined past them, not moving at the speed of light. Now as it shined past them, they point one in the same direction as it is moving twords another planet on past them. There light would travel faster then our's reaching it earlier then our's. But that planet is moving twords them at a good clip. There light would be moving faster then light as it past them, amazing there scientist's crushing there theory of light speed. Then ours' makes it and they are puzzeled at the speed of ours' even at a differant speed. You see, light speed my be a constant in as they way the photons move, at one speed but not something like a ship moving with drive that propel's it along at what ever speed they might feed into it drive engine. That ship my be moving along at only say, have the speed of light and something moves by at have the speed of light to it. Then the ship see's it as moving by AT the speed of light as they measure it. That shows me that just photon's move at that speed, not anything else that wants to move faster then photon's. This is so hard to put into words, but i have always been able to "See Thing's" in a bigger picture, like observing it from above looking down at the univirse. Hard to explain, for sure. I understand how things work, atoms and how it is all made up. From the big bang to the making of system's and there forming of planets. That is one reason i wanted to put up the satellite for The UFO Discovery Project. It was going to have a small telescope also and we were going to use it for astronomy research also.

Yea, i went deep on this one, lol. Sorry. Just love Science stuff and finding a nabor so close just got me going. We need to point a radio telescope at this new nabor and listin in for a while. But i'm sure that one would fall on deaf ear's to SETI. There just a money maker and could care less if they find anything. Have you ever heard the director, Seth, speak about UFO's. He laugh's about it, making fun of us that do believe. He was on Larry King with James Fox as a debunker. He was as bad as Bill Nye, the science guy about it. It just showed me that SETI could care less about contact. I'll end it here and wait on some reply's on this one.
