Great Debate Series
Many of the questions posed by
astrobiology are the subjects of intense debate within the scientific
community. How did life originate? What kind of life forms should we
expect to find on other worlds? Is there life on Mars, or on Jupiter's
moon Europa? How will we know for certain when we've found evidence of
life on other worlds?
Our Great Debates series will show you the
process of scientific debate in progress, as prominent scientists sift
through the available evidence to reach what are sometimes directly
opposing conclusions. |
