Artist's impression: Kepler has identified many exoplanets, but some are in their star "Goldilocks zone"
One of eight new planet discovered in distant solar systems has the title of "alien world most Earth-like" spoofed astronomers said.
All eight were captured by the Kepler space telescope NASA last in 1000, where his record of these "exoplanets".
But only three sitting securely in the "habitable zone" of their host star - and in particular, is rocky like Earth, but also a little warmer.
The Fund was revealed at a meeting of the American Astronomical Society.
Red Sky
The three potentially habitable planets Kepler Connect "Hall of Fame", which is now about eight fascinating perspective planet.
And researchers say the Earth as newcomers, like Kepler 438b is known, is probably closer to our house, Kepler 186f - most likely seen our twin.
In 12% larger than the Earth, the new candidates is greater than 186f, but it is closer to our temperature, probably only get 40% more heat from the sun that we have of our own.
So if we are on the surface 438b, it may well be warmer than here, Dr. Doug Caldwell Seti (Search for Extraterrestrial Intelligence) Institute in California.
"And this is a [red dwarf] cooler stars ... so your sky would be redder than ours do not expect," said Dr. Caldwell.
The three newcomers 'Hall of Fame' Kepler expanded to eight small, residential area exoplanet
The meeting in the first person is unlikely - both because the planet is 475 light years, because we still essentially no idea what he has.
Images of the Kepler telescope, which looks behind the earth, and distance, as we orbit our Sun Trails are used to identify "transits" distant planet by observation.
It is the variation of the starlight when a planet passes by.
A large team of researchers then used additional data from ground-based telescopes to explore this strange solar systems.
Attempts to calculate the size of the planets are, and how they orbit their host star.
Not all such failure eventually causes appears to be a planet to be, but.
At the same time that the eight new exoplanets have been confirmed by a team of 26 members spanning NASA and announced several US institutions own scientists Kepler mission issued a new tranche of more than 500 planets "candidates".
"With more observations, some of these candidates can not turn on the planet," said Kepler Scientific Director Fergal Mullally.
"Or, as we better understand their properties, they can move in or even outside the habitable zone."
'Star Trek' scenario
Never scientists have confirmed exoplanets anointed candidate, the question is whether it is "Earth-like" full with blurred boundaries.
The size of the habitable zone, or "Goldilocks" in which a planet is far enough, but not so far from the sun to keep the water freezes depends on the trust that scientists want to be with their conjecture,
According to Dr. Cardwell, only three of the eight new exoplanets can be sure placed in this area - and only two of them are likely to be rocky like Earth.
A more detailed description is very difficult.
For Kepler 186f, experts say, now known as the "most similar to Earth" exoplanets was wearing an artist
"Among the Kepler measures and other steps we have made, we do not know if these fish planets oceans and continents with trees," said Dr. Caldwell BBC News.
"All we know is their size and the energy they receive from their star.
"So, we can say: Well, a size that they are likely to be rocky, and the energy they get is comparable to what the earth.
"Since we are in these gaps in our solar system, we do not meet, we learn more about what it means like Earth, in a sense."
On a similar event at the conference, Prof. Dr. Debra Fischer of Yale University, said she remembered a time until the first exoplanet discovered that. More than two decades
"I remember that astronomers worried before point," she said.
"We really step back and say .. Maybe the Star Trek picture is wrong that filled me with despair"
Professor Fischer said that sensitive telescopes such as Kepler had ushered in an era of "incredible and impressive work."
"We're talking about a planet to speak - and we see only their stars with a powerful telescope.
"And we can draw graphs and sketch its composition and the serious scientific discussion. It's amazing."
