Kepler Planet 16 Sunset two common B

Two sleep together every night has fallen on the planet Kepler-16b, say researchers in the journal Science on Thursday.

Events like science fiction was supervised researchers who do the ship pengamtan NASA's Kepler. Scientists have discovered a planet orbiting two stars - for the first time such a phenomenon confirmed its existence.

"It 'really amazing Kepler measures" says Alan Boss of the Carnegie Institution of Science, along with the author of the study report. "It 'really interesting to have a planet orbiting two stars," he said.


The stars of two in two to two mutually Sun rotation - are already known and so far astronomers suspect that there are planets in orbit. Kepler's observation is the first confirmation of this fact.

Gravity of double stars, even a relatively small, as the stars in the center of this system of astrology, a very different severity of the star, the boss said by telephone.

Kepler's mission is to explore the Milky Way about the existence of planets in "habitable zones" are not too close or far from the stars that orbit.

The spacecraft will make its stars found in the periodic dimming of light, which means that a celestial body that orbits - Planet - moving between the star and Kepler tool. This is known all over the planet.

What is surprising is that the stars eclipse each other when the star is blocking the other. The eclipse shows that a third planet to be part of the system.

Because of his son, both smaller and cooler than our sun, Kepler planet-16b is very cold, with surface temperatures around minus 73 degrees Celsius at least 101, said the Harvard-Smithsonian Center for Astrophysics in a statement. Josh Carter is the author of the Institute in collaboration with the research.

Kepler 16b is a gaseous planet cool with the same size and mass of the planet Jupiter, which orbits the Sun every 229 days at a distance of 104,600,000 km. This distance is approximately equal to the orbit of Venus. Earth orbits the Sun every 365 days at a distance of approximately 149.7 million kilometers.

The newly detected planet is 200 light years from Earth and it is estimated that there are no life forms there. A light year is the distance that light in one year, about 10 trillion km.

Astronomers Find Darker Planet

The planet outside the solar system, dark, darker than a piece of coal, is found by astronomers. Jupiter is a planet orbiting its star at a distance of about five million miles, and the possibility of a temperature of 1200 degrees Celsius.

The planet is probably too hot to support reflective clouds as seen in the solar system. nnamun so it still can not explain why the planet is so dark. This study will be published in the Monthly Review press of the Royal Astronomical Society.


The planet, called TrES-2b are in the Transatlantic Exoplanet Survey in 2006. The distance from Earth at about 750 light-years away in the constellation Draco. The planet is in the space telescope Kepler in the order, with the aim of finding extrasolar planets using a measure of the light sensitive.

Using data for the first four months of Kepler, David Kipping, a researcher at the Center for Astrophysics at Harvard University and David Spiegel of Princeton University to evaluate the amount of light emitted directly from TrES-2b.

They measure the amount of light the "night side" of the planet, when directly in front of its star. Then compared with the light of the "dark side" before crossing the star.

The differences were then measured how much light is reflected or is called albedo.

In the solar system, Jupiter, clouds on the planet reflects light by 52%, 37% of the land reflects light. But it seems that the planet TrES-2b reflect the light beam is less than 1% of the star. "The albedo is darker than the acrylics or charcoal." Strange, "said Kipping told the BBC.

One explanation could be that the planet is too hot to support reflection clouds surrounding the planet as seen in the solar system. However, Kipping and Spiegel said it was not yet able to explain why TrES-2b as dark. Not only because the world does not reflect the rays of light, but is likely to absorb, he said.

50 new planets discovered, perhaps only one of the Abandoned

European astronomers have discovered 50 new planets in our solar system. Of these, 16 of them have Earth-sized planet.

Largest planet discovered planet called HD 85512 b, which measures 3.6 times the mass of the earth, can be reached within 36 light years and lies in the constellation Vela. The results also indicated that nearly half of stars like our sun is shining and a few bright as Saturn.

Planets like Earth, scientists believe that there are traces of water in there that does not give life there.
The results are presented on the Planet Extreme Solar Systems conference in Wyoming, USA. The conference was attended by about 350 experts from around the world.


These new planets discovered by a mission with great precision Radial Velocity Planet Searcher (HARPS), mounted at the European Southern Observatory at La Silla in Chile.

"The detection of HD 85 512 b away from the border HARPS, and suggests the possibility that the discovery of super-Earths (super-Earth), which allows life to exist around stars like the sun," said astronomer University of Geneva, Michel Mayor.

A team member, Lisa Kaltenegger, Max-Planck-Institute for Astronomy and the Harvard Smithsonian Center for Astrophysics, said the results mark a new era in the search for past life on Earth. "We are entering an extraordinary achievement in the history of astronomy," he said.

Man Is an Ancestor of The Alien on Mars?

The planet Mars has become the center of attention in the context of human space exploration. There are two things that give the red planet: if there is life there, and if Mars could be colonized by humans, if later in the Earth can not sustain life.

But the latest research by scientists of both intelligent world-class universities, MIT and Harvard was more advanced and revolutionary. You want to prove the feasibility of the tree of life on Earth has its roots in March. The researchers also created a tool to prove the allegations.

The device is called the Search for Extra-Terrestrial Genomes, or SETG. The tools are under development, examining samples of Martian dust, to isolate the genetic material, which can occur - in the form of insects or other living creatures, who died a few million years ago.


This tool, researchers can use the normal biochemical techniques to analyze the result of genetic sequences and compare the results of the earth.

"This is a long term project," said the researchers at MIT, Chris Carr has published Space.com. "Jikan later, we found no link with the Earth, the Earth may be a creature from Mars. Or, vice versa, and sent from Earth to Mars."

The idea that living organisms on Earth came from Mars might not be on everyone's mind. However, this is not a crazy idea.

For although this time the surface of Mars a cold, dry and free of all life - There is ample evidence that the planet was warmer and wetter billions of years ago.

As on Earth, when life depends on water. Ancient Mars may have been a supporter of a type of life - perhaps even before the Earth. Similarly, the researchers said.

If this happens, Martian microbes may have mengkolonialisasi Earth when a giant asteroid glide to Mars and make the particles splash and then travel experience between spaces. Researchers estimate that one billion tons of Martian rocks that have traveled in recent years.

And microbes are very strong, so it may be that some of them could have survived the impact of asteroids, and to a new home on another planet. Adding to the car, the orbital dynamics of the show is 100 times easier to Mars rocks to Earth and not vice versa.

However, Carr said, is less likely to find something on the surface of Mars. Ways you can do is dig. "There are two possibilities, Mars has life or not. But we want to be sure."

Meanwhile, the U.S. space agency has no opinion seoptimis researchers. "It is not plausible that life on Mars associated with life on Earth - and called on the two planets from genetics," says astrobiologist from the Ames Research Center of NASA in Moffett Field, California Chris McKay. But "in all cases, it will be important to test this hypothesis."

White House Official Statement About The Alien

White House has issued an official statement confirming that there is strong evidence that if foreigners (ETS), or strangers ever came in contact with people.

The declaration is a formal response by the United States after the two requests that appear in the pages of the White House: "We the peoples."

The page is meant to express their grievances and the Citizens 'Initiative petition' against the President of the United States and the United States government, and respond, if enough people sign it.



Both petitions for aliens who have managed to collect 17,000 signatures, of the "quickly reveals knowledge of the government on foreigners and government communications with them," and "was officially made a statement on the presence of extraterrestrial-related human -. Disclosure of secrets "

"The U.S. government has no evidence of extraterrestrial life exists, or if there are foreigners who come into contact or contact with humanity," said the high level of policy and communications division of the White House, Phil Larson , in a statement.

In addition, Larson said, there is no credible information that there is evidence that hidden to the public.

Even so, Larson said it is possible extraterrestrial life were discussed and studied, including a series of NASA projects. It does not even rule out that it was true.

"Many scientists and mathematicians came to the conclusion that there is a fair chance, somewhere between billions of stars in the universe, there are other planets outside the Earth where we live," at he said.
