"Another Earth" Let Us Closer To Aliens

If the Kepler-452b have the same trajectory with the Earth, it is likely that the emergence of life on the planet.


Kepler-452b discovery allow scientists closer to a livable planet, even alien life. According to scientists, the understanding of habitable planets, Kepler-452b with certain congenital conditions, such as a 60-billion-year history, there are quite a lot of time left to the evolution of life, with Earth-like development if Kepler-452b have trajectory, it is likely that there has been life on the planet. But the scientists also said that Kepler-452b livable bring in little time, remaining around 500 million years, if there is the presence of civilization on the planet, they should be action.

In terms of looking for aliens, Stephen - Hawking and Russian billionaire Yuri - Milner launched a new program to find extraterrestrial civilization, be prepared to spend 10 years to complete the solar system around the star system scan. They will use the 100 meters in diameter, Robert C. Byrd Green Bank Telescope and New South Wales Parkes telescope, listening universe unknown signals. Stephen - Hawking monitoring plan to further than the Kepler telescope, trying to find a direct activity traces of extraterrestrial civilizations, listening range farther.



Kepler-452b only 1400 light-years away from us, this distance is just at the minimum distance between civilizations communicate with each other. Some studies show that 1000 light years is a threshold, this distance is greater than the expected discovery of extraterrestrial habitable planets or life. From the current perspective, Kepler-452b is the existence of life has the potential to place, then NASA will be spectral analysis to determine the composition of its atmosphere, if there is water and vegetation, we will know. In view of the Kepler telescope observations radius of 5,000 light years, unable to find extrasolar planets farther, so Hawking's surveillance program or its necessity.

Once life on Kepler-452b, what does it mean for us? First, the scientists wanted to know whether it is an advanced civilization, if you exclude intelligent life, then the next question is what they look like, if life in the universe have a common origin, and so on. Studies have speculated that Earth's species may come from the more advanced civilization, they will spread the species to other planets. To uncover the origins of life on Earth, we first have to find extraterrestrial life, which you can find where they come from.
