Welcome to Babylon 5!
Babylon 5 is an American space opera television series created by writer and producer J. Michael Straczynski, under the Babylonian Productions label.
The television series takes its name from the Babylon 5 space station, located in the Epsilon Eridani star system, at the fifth Lagrangian point between the fictional planet Epsilon III and its moon. Babylon 5 is an O’Neill cylinder five miles long and a half-mile to a mile in diameter. Living areas accommodate the various alien species, providing differing atmospheres and gravities. Human visitors to the alien sectors are shown using breathing equipment and other measures to tolerate the conditions.
The five seasons of the series each correspond to one fictional sequential year in the period 2258–2262. Each season shares its name with an episode that is central to that season’s plot. As the series starts, the Babylon 5 station is welcoming ambassadors from various races in the galaxy. Earth has just barely survived an accidental war with the much more powerful Mimbari, who, despite their superior technology, mysteriously surrendered at the brink of the destruction of the human race during the Battle of the Line.
