The spring outside Solar system is similar to the terrestrial autumn
Goddard Space Researches Center scientists assert that can forecast the color of plants on planets outside the Solar system. According to the researchers` conclusions, plants can be not only green, but yellow or red.
It is known that solar spectrum contains different colors. The atmosphere of the Earth as an optical filter absorbs different colors of a spectrum in a different degree. As a result more red light particles reach terrestrial surface, rather than blue or green. Consequently during photosynthesis the chlorophyll of plants absorbs mainly red color of a solar spectrum and a little bit blue. So plants on the Earth have green color which is not absorbed but is reflected by leaves of plants. And the human eye sees the reflected color.
Studying the light, which is absorbed and reflected by plants on the Earth, researchers came to a conclusion, that if we find plants on the planets revolving around remote stars, we shall see not green plants mainly.
Not all stars have the same color spectrum as the Sun, and characteristics of the atmosphere on planets outside Solar system can considerably differ from Earth atmosphere. Scientists came to a conclusion that photosynthesis on far planets can considerably differ from that on the Earth.
