Our project is based upon the news paper article that was published in April 11, 2007 by NASA, and the title is NASA Predicts Non-Green Plants on Other Planets. On the news paper articles it talks about scientists predicting that some planets might have mostly non-green plants, such as yellow or red-dominant plants. This idea was developed by researchers and scientists looking at the changes in that light through different atmospheres, and from the results they identified the colors that would be most favorable for photosynthesis on other planets. Each planet will have different dominant colors for photosynthesis, based on the planet’s atmosphere where the most light reaches the planet’s surface. On Earth, Kiang and colleagues surveyed light absorbed and reflected by plants and some bacteria during photosynthesis, and from that they found out that organisms that live in different light environments absorb the light colors that are most available. It explained photosynthesis that happens in Earth by saying that the Sun has a specific distribution of colors of light, emitting more of some colors than others. Gases in Earth's air also filter sunlight, absorbing different colors. As a result, more red light particles reach Earth's surface than blue or green light particles, so plants use red light for photosynthesis. Carl Pilcher who is a director of the NAI at NASA Ames said "This work broadens our understanding of how life may be detected on Earth-like planets around other stars, while simultaneously improving our understanding of life on Earth." Also Victoria Meadows who is an astronomer who is head of VPL said “This work will help guide designs for future space telescopes that will study extra-solar planets, to see if they are habitable, and could have alien plants.”
