Uni ready for next ET

The UK's Edinburgh University is planning to enroll thousands of students this month on a course to learn how to search for aliens.

The university has joined some of America's top institutions in launching a series of free online courses - including an Introduction to Astrobiology and the Search for Extra-terrestrial Life.

The course will discuss such questions as: What are the possibilities for intelligent life elsewhere? How would society deal with contact with aliens, and who would represent Earth?
