The Mystery Planet Livable Soon Revealed?

Mas Aal - Exoplanets are planets located outside our solar system. This planetary scientists to uncover the target is there life beyond Earth.

Reported Astrobio, Friday (07/19/2013), astronomers have not been able to solve the mystery is there alien life on exoplanets. Nonetheless, these researchers actively looking for habitable planets that could potentially use several criteria.

Ideally, researchers would like to find a planet that has similarities with Earth. Therefore, the researchers focused on hunting planets has exactly the size of Earth orbiting at the right distance from their star.

The exact location of exoplanets with their parent stars called habitable zone (habitable zone). NASA's Kepler Mission, a flagship instrument space agency NASA to help scientists in the search for alien life is.

Some of the findings of exoplanets, planets reportedly nicknamed 'Goldilocks' who came from a fairy tale, in which the alien planet has conditions suitable to support the emergence of life. Kepler and other space telescopes helped researchers to be able to confirm the existence of extraterrestrial life.

Scientists have also been dubbed exoplanets larger than Earth as Super Earths. Search the twin planet Earth, the planet is in the middle of the habitable zone of intensified research.

The habitable zone is the 'belt' around a star, where temperatures are considered ideal for the emergence of water. Water is an essential element for life. Earth for example, lies in the habitable zone of sun.

Outside the area or zone, the planet would be too cold and frozen. Thus, it is not suitable as a place to be uninhabitable. While the planet is between the star, although included in the habitable zone, but the temperature of the planet would be too hot and steamy.

Goldilocks planets has the potential for some kind of abundant life, even microbes. In a recent study, researchers based at NASA's Exoplanet Science Institute at the California Institute of Technology analyzed the potential location of a planet called Kepler-69c.

This planet has a size of 1.7 times the size of Earth. Than the so-called Super Earth, this alien planet is said to be similar to the Super Venus.

"On the way to search for Earth, Kepler tells a lot about the frequency of planets in our galaxy resemble Venus," said Stephen Kane, a researcher and lead author of the Kepler-69c, published in the Astrophysical Journal Letters.

Scientists want about more about a potentially habitable planet. They also look at the arrangement of molecules planets with signs of greenhouse gases. Sophisticated space telescope expected future can trace signs of oxygen, water, carbon dioxide and methane on an alien planet.
