Astronomy Science ~ To help identify extraterrestrial life, astronomers and experts have made the color table aliens. This color is derived from the 137 chemical fingerprints of various types of micro-organisms, some of which come from the most extreme environments on Earth. If the same abundant life form on the '' exoplanets '' outside the solar system, they can be recognized from their wavelength of the reflected light.

In the same way, a distant observer who saw the earth will record a greenish color due to the abundant vegetation on Earth. Photosynthesis of plants appear green because they absorb wavelengths of light in accordance with the other colors. Only the green visible light is reflected back.

The scientists, led by Siddharth Hegde of the Max Planck Institute for Astronomy in Heidelberg, Germany, wrote in the journal Proceedings of the National Academy of Sciences: "'This catalog provides broad coverage traces of life on exoplanets, which can provide different conditions of the earth, for example, extremophiles on Earth became the dominant life form.

"A lot of the history of life on Earth has been dominated by microbial life, and there is the possibility that life on exoplanets also develop through stages of single-celled creatures before it develops into a multicellular creatures.
'' Here, we present the first database, to our knowledge about this in preparation for the next generation of ground-based telescopes will find a variety of life on exoplanets. ''

Approximately 2,000 planets have been found orbiting distant stars, some of which occupy '' habitable zone '' in which the temperature is steady enough to allow liquid water to survive on its surface and that enables life on Earth evolved like. The next stage of research on exoplanets will involve the investigation of the atmosphere and the reflection of light to look for traces of life.

Indirect signs of life - a byproduct of life - can be found such as ozone, which is derived from oxygen, and methane. But looking for something like a green leaf on the surface of the planet 'will provide more direct evidence of life, scientists said. The presence of an alien organism that covers most of the planet's surface area can be confirmed from its pigmentation.

In the new study, the researchers collected 137 different species of micro-organisms that cover a wide range of colors and environments ranging from the Atacama desert to the ocean Hawaii. These colors include dark red, yellow, pink, green and brown. There are plans to collect more samples and add color catalog life.

But the scientists showed that for detecting traces of color living organisms on the planet's surface would be very challenging. It is currently not possible to measure the direct light from Earth-sized planets because they will be drowned out by the brighter light.
