POSTED JUNE 1996. The discovery of a planet that could resemble Jupiter in its size and orbit is focusing attention on this ageless question: are we alone in the universe?
We'll discuss the search for "little green men," I assure you. But first, let's take a look at the newly discovered planets.
(Feeling non-linear? Then dive right into the middle of the story:)
How in the world do they find planets, anyway?
Planets have been identified around five stars so far. But maybe they're not really planets... A cautionary note from an informed contrarian.
Take cover: the solar system is going to collide with a dense cloud of interstellar gas.
Who's happening with the search for brains in outer space?
Responsible humanoids identified at last!
