Is this the overview of Our Earth fate?

A bright shining star, within 2,800 light years from Earth 2 will devour planets orbiting him. The time is long indeed, millions of years from now. Kepler-56, is a star like the Sun, he slowly enlarged, resembles a swollen red giant. Once he moves into this phase, Kepler-56 and then will devour the nearest planet, Kepler-56b, within 130 million years. Kepler-56c, the second exoplanet turn destroyed about 25 million years later.
In this artist's conception, the doomed world Kepler-56b is being tidally shredded and consumed by its aging host star. New research shows that Kepler-56b will be engulfed by its star in about 130 million years, while its sibling Kepler-56c will be swallowed in 155 million years. This is the first time that two known exoplanets in a single system have a predicted "time of death." (Picture from: http://bit.ly/1u9Xwex)
"It's very exciting because for the first time we can observe extrasolar system where two planets sentenced to 'death penalty'," said Gongjie Li of the Harvard-Smithsonian Center for Astrophysics (CfA), as quoted from Space, on Wednesday, June 11, 2014. "We have calculated the time of their execution."

The scientists argue that ultimately the Solar System, in which the Earth is going to meet the same fate as the Kepler-56 system. About 5 billion years, the Sun will become a red giant bulging. Mercury and Venus will be the first victims when the Sun end to his life.

Kepler-56c - which will be devoured - somewhat similar to Saturn. While other planets are similar to Neptune will perish. Kepler-56b orbits its star every 10.5 days, and Kepler-56c makes a full orbit every 21.4 days. The two planets orbit closer to its star than Mercury is to the Sun.

Once Kepler-56b and Kepler-56c devoured, only one planet we know is still allowed to exist, the planet Kepler-56D, a gas giant that orbits its star in a relatively safe distance. He still will be saved when the star becomes a red giant swollen.

Li added, when scientists observed the death of the two planets, they might be able to see a 'dead' planet after being abandoned by its star. That will happen in the Kepler-56D. Possibility, the giant enveloping gas will burn, "said Li." Then, the possibility of the planet's core will be missed. So we will see a corpse floating planets in the universe. "

And, there are chances of true scientists have found the 'bodies', the orbiting another star that has passed the red giant phase and then be dead. Something that might occur in the human planet.

Dying Star
Previously, in 2012, scientists discovered a strange spiral structure surrounding a giant red star that is dying: R Sculptoris. The spiral is found international team of astronomers using telescope Atacama Large Millimeter / Submillimeter Array (ALMA) in northern Chile. The spiral form of the material coming out of the star.

To note, a star like the Sun will expand into a red giant in the last stage of its evolution. When the sun reaches this stage in about 5 billion years, its outer layer will spread as far as Earth's orbit.

Two years earlier, scientists at the Chandra X-ray Observatory belonging to the United States Space Agency (NASA) found the star 'cannibal' who are fond of devouring its neighbors. Red giant billions of years old is named BP Piscium (BP Psc).

BP Piscium is an evolutionary version of the Sun is located about 1,000 light years from Earth. The star is located in the constellation Pisces. Scientists began studying the BP Piscium 15 years earlier and confused by the unusual appearance.

The orbit of a dusty disc or disc material that is usually a proof of start formation of planets around new stars. The scientists even believe the Earth may someday suffer the same fate with the stars unfortunate that devoured BP Piscium. Why?

Earth is in the solar system, with the Sun at its center. "BP Piscium shows us that stars such as the Sun may live quietly for billions of years. However, when it evolved into the final stage, the Sun could have swallowed a star or two planets around it," said David Rodriguez of the University of California, Los Angeles . *** [EKA | FROM VARIOUS SOURCES | SPACE]
