Earth from Moon "We consider the Earth to the moon observations as if it were an exponent called used to move," Michael (ESO) Steric, the paper's lead author.. Gases in the atmosphere that astronomers are looking for telltale signs of organic life in the moonlight as some combination of indicators, analyze the faint light. The method of life on planets outside our solar system to explore the future as a benchmark that represents the earth. Fingerprints of life or bio signatures are hard to find with traditional methods, but the team is a new approach that is more sensitive. Instead of seeing just how bright the light is reflected in different colors, but also look at the polarization of light, called a point of spectropolarimetry. To apply this technique to very strong reflect light from Earth with the VLT show bio signatures inspection by moonlight. Study Stefano Bagnulo (Armagh Observatory, Northern Ireland, United Kingdom) co - author explains the advantages: "overwhelmed by the brightness of a distant exponent host star's light, it is very difficult to try to analyze a bit like the dust an indictment of a powerful light bulb for further study. "But a polarized light is reflected from the planet, the light from the central star, it's so blinding light of the stars polar metric techniques help us to select an exponent reflected light of the weak. Not." The team colors and the reflections of the moon from the earth to study the degree of polarization of light, light as if it came from an exponent. It was able to get them, those are cloudy atmosphere, its surface covered by oceans that part, and it is important that vegetation is present. "Finding life outside our solar system depends on two things: If there is, and the technical ability to identify with life in the first place," said co-author Enric Palle (Instituto de Astrofísica de Canarias, Tenerife, Spain) says. "This work is an important step toward achieving this capability." Spectropolarimetry Finally, if you can tell us a simple plant life, arising elsewhere in the universe based on photosynthetic processes Sterzik concluded. "But we certainly are seeing little green men, or for evidence of intelligent life." be.
