radiation from its explosion (traveling only at light speed) was able to reach Earth. In a 1988 storyline, Superman traveled to the former site of Krypton to discover that the planet was slowly reforming from the vast sphere of debris remaining. It would take millions of years before the planet would be solid again. This sphere of debris had been turned to kryptonite by the planet's destruction, and the radiation caused Superman to have a hallucination in which the entire population of Krypton came to Earth and colonized the already inhabited planet, prompting Jor-El to initiate a Terran-based resistance movement, pitting him against his estranged wife Lara and now-grown son Kal-El, at which point the hallucination ended. In Superman: The Man of Steel Annual #3, "Unforgiven" - an Elseworlds tale - Jor-El convinces the Science Council to relocate selected Kryptonians to Earth.

Superman: Birthright In the 2004 miniseries Superman: Birthright, a new retelling of Superman's origin and early years, Mark Waid located Krypton in the Andromeda Galaxy 2.5 million light-years away, and adopted elements from several previous versions of the planet.

In previous comic versions, it was assumed the "S" shield on Superman's costume simply stood for "Superman"; in Birthright, Waid presented it as a Kryptonian symbol of hope; he borrowed and modified a concept from Superman: The Movie, wherein the "S" was the symbol of the House of El, Superman's ancestral family.
