Icy bodies: Europa and elsewhere

The new discipline of astrobiology that is, the science of searching for extraterrestrial life, is not only rapdly growing, but has also captured the public imagination. This free course, Icy bodies: Europa and elsewhere, examines the emergence of icy satellites of distant planets as potential sites of extraterrestrial life, looks at the potential for life on Jupiter's moon Europa, and speculates on the ethics of searching for life elsewhere in the solar system.
