The Color of Plants on Other Worlds If it isn't easy being green on Earth, where chlorophyll is well tuned to absorb most of the energy in our sun's yellow light, imagine the difficulties elsewhere in the galaxy. Plants growing on worlds around cooler, brighter or more tempestuous stars would need to rely on red, blue or even black pigments to survive.

But what are the other steps, and how do they feed into the possibility of life elsewhere? These interesting questions relate to how long the biosphere will be tenable for life as we know it.

Meteorites delivered the 'seeds' of Earth's left-hand life Breslow simulated what occurred after the dust settled following a meteor bombardment, when the amino acids on the meteor mixed with the primordial soup.

Microscopic Fuzz May Be Best Evidence of Martians If Martian life existed a few billion years ago, scientists think any plant-like microbes would have left behind a stringy fuzz of fibers. That's because here on Earth, researchers now say they have found such ancient fuzz, called cellulose, preserved
