Viewed from a star in some other comer of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow, Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds—which are all too small to be seen from such a distance-reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own.

Scientists have long believed one way to stop the Earth’s atmosphere from warming is by planting more trees. The idea is that more trees will take in or absorb some of the carbon dioxide in the atmosphere. Carbon dioxide is a gas released by cars, factories and other human activities. The gas traps heat in the Earth’s atmosphere, which warms the planet. However, two new studies have found that trees may not be as helpful in reducing carbon dioxide as had been thought.
