 Scientists have determined that life can be detected from space, using data collected from the Galileo spacecraft. it indicated that, no matter earth's orientation and distance, chlorophyll-based vegetation generated a spike at 700-nm that doesn't exist on planets that we know don't have vegetation (that is, every other planet and moon in our solar system). It should be possible to detect this spike on planets around other suns, but there are significant technical challenges to overcome. |
