Second Earth to humans there might be around a dying Star

HD 140283, the oldest stars in the milky way on planet, it turns out that the known age. Lisa Kaltenegger said, old stars may keep a second Earth.

Post Compass - Currently astronomers generally think that habitable planets that might be a second Earth for humans is similar young stars in the Sun.

Lisa Kaltenegger from Carl Sagan Institute at Cornell University presents a revolutionary new views.

In his paper published in the Astrophysical Journal on Monday (16/5/2016), it says that the Earth is both for humans may be around stars dying.

"We can look for new places may become a Livable World right there," said Kaltenegger.

The fate of the star more or less like a human being. They will ripen. When the aging, the stars will lose energy aka fuel life, becoming a dying, then dead.

Sun also will die. Scientists estimate the time of death, the Sun is around 5 billion more years.

The idea that dying stars can have a habitable planet is actually not really new. Alan Stern of the aviation and Space Agency (NASA) said the United States, as the Sun appears, in the habitable zone of the solar system will shift.

Stern said, as the Sun, Pluto and aging month, Charon, is probably going to be livable.

However, together with his colleague Kaltenegger Ramses Ramirez, only that possibility through a study based on the results of modeling. They analyze the stars off of the solar system.

According to them, Pluto and Europa, a moon of Jupiter, will not be nice to live in. The atmosphere binds too little gas to support life.

However, Kaltenegger and Ramirez found 23 star approximately 100 light-years away potentially habitable planet has.

The stars were known as "slow burning star", the actual slow. Period of dying to death stars were longer than the Sun.

With a period of dying to the old dead certain, the planet could be habitable zone for 9 billion years.

"We do not know if there is a planet there because no one was ever looking for. Nobody thought about it, "said Kaltenegger Washington Post, was quoted as saying Monday.

But at least, scientists now have a new target location to search for habitable planets. Munginkah's really no second Earth in there? Let's look forward the next findings.
