Krypton in transition

Over the course of the 1940s and 1950s, various alterations and additions to the makeup of Krypton were made in the comics. Among them was an explanation of why the natives of Krypton perished if they had possessed super powers on their native world (as was the case in the earliest versions of Krypton outlined above, although this only became a problem once Superman — and by extension anyone from Krypton — was portrayed as increasingly powerful, able to withstand nuclear explosions, contrasted with his original power level in which a bursting mortar

 shell could penetrate his skin).

Thus, it was explained by the early 1950s that Kryptonians were powerless on their own planet, and would gain super powers only within a lower gravity environment. This matched the correct theories being published that when man reaches the moon (a lighter gravity environment) he will be able to lift great masses and leap great distances. In the early 1960s, added to this was the need to be exposed to the rays of a yellow sun

, which was older and cooler, or put out less energy) to gain super powers, with the yellow sun aspect soon gaining the much greater emphasis. Other changes to the concept of Krypton and its culture were introduced, many of which were stylistic.

Silver Age Krypton

By the late 1950s, Krypton played an increasing role in various Superman stories, with greater detail provided about Krypton's makeup.

History

Kryptonians made use of their advanced science to create a world where scientific inventions and research influenced much of daily life. Robot

s and computers were used for many tasks on Krypton, even for determining what career paths young boys and girls would take as they grew up. Scientific and technological research were highly valued on Krypton, with the ruling body of Krypton named the "Science Council".

Several stories featured characters traveling back in time to visit Krypton before its destruction; one example is the 1960 story "Superman's Return to Krypton", in which Superman is swept back in time to Krypton some years before its destruction. Powerless, he spends some time on the planet, where he meets his future parents-to-be and falls in love with a Kryptonian actress named Lyla Lerrol

. A Superman "imaginary story" entitled "What If Krypton Had Not Exploded?" (reprinted in the trade paperback edition The Greatest Superman Stories Ever Told) gave more insight into Krypton's society.

Superman's Kryptonian heritage was a frequent factor in Silver Age Superman comic storylines, as he was fully aware of his origins from an early age. Superman would use this knowledge for such tasks as constructing advanced Kryptonian technology or observing some of Krypton's traditions.

Moons

Krypton had two moons, but one of them - Wegthor - was accidentally destroyed by the criminally deviant Kryptonian scientist Jax-Ur

Eventually this disagreement led to open violent conflict especially after it was openly discovered that a woman's cloned copy of herself was allowed to gain full sentience and to establish a full, normal life. However, when a young man (the original woman's son) had discovered that his fiance was this clone, he killed the clone, and then publicly killed his mother, and also attempted his own suicide before being stopped. This key incident ignited the Clone Wars, during which Kryptonian science was turned to warfare and several super-weapons were developed and used. Among them were the devices which became known as the Eradicator

At the time, it was believed that although the use of the Destroyer resulted in a nuclear explosion which eliminated the post-crisis city of Kandor, the device had been stopped before it could achieve planetary destruction (ironically, by an ancestor of Jor-El

 himself), but centuries later Jor-El would discover that the reaction had only been slowed to a nearly imperceptible rate and would eventually destroy the planet as intended.
Destruction

In the meantime, though it had for now survived the war, Krypton was scarred deeply by it. The formerly lush garden world was burned and blasted, left mostly a lifeless desert. In direct contrast to the society that had existed prior to the Clone Wars, a sterile, emotionally dead civilization emerged. The population became isolated from one another, living in widely separated technological citadels and shunning all personal, physical contact. Procreation would then become a matter of selecting compatible genetic material which would then be placed within an artificial womb called a "birthing matrix". Any attempt to contact other worlds was forbidden, and the planetary government maintained an isolationist stance, forbidding space exploration of any kind.

It was into this world that the young scientist Jor-El was born. By his adult years, the mysterious "Green Plague" was killing Kryptonians by the hundreds, and upon researching the matter, Jor-El discovered that the cause was growing radiation produced by Krypton's increasingly unstable core. Due to this process, the entire planet itself was going to explode.

Unable to convince his associates to abandon tradition and consider escape, and reasoning that modern Kryptonian society had grown cold, unfeeling and thus decadent Jor-El removed the Eradicator's planetary binding genes from his genetic pattern, took the birthing matrix of his unborn son Kal-El and attached a prototype interstellar propulsion system to the vessel. Just as the planet began to shake apart, he launched the matrix towards Earth, where it would open and give birth to the infant upon landing (the post-Crisis Superman therefore was considered to be technically "born" on Earth). Jor-El was not only determined that his son would survive the death of his birthworld, but that he would grow up on a world that vibrantly embraced living, as his pre-Clone Wars forbears once did.

Whether this further revision of continuity has an in-universe rationale is as yet unknown, but it may stem from continuity changes wrought by the reality-fracturing conclusion of Infinite Crisis.

Krypton's revisions

Krypton and its history has been altered to a great extent from its previous versions. In the post-Crisis Krypton, sexual reproduction was considered obscene, and thus, all children were conceived in birthing matrices. After Infinite Crisis this was taken out of Kryptonian culture. Also in post-Crisis Krypton, this planet was located in a solar system within the Milky Way galaxy close enough that the radiation from the explosion (traveling only at light speed) was able to reach Earth (Action #600). But after Superman: Birthright

 altering the genetic codes of Kryptonians to keep them planet-bound after a group of them left Krypton to explore and colonize other planets. The Eradicator punished these Kryptonians by altering their genetic codes to be vulnerable to lead, which resulted in the Daxamites.

Originally, Jor-El had a serum that he invented that would allow a Kryptonian to leave the planet safely; which he gave to his son Kal-El upon leaving for Earth. This was created to maintain the rule of Superman being the only Kryptonian survivor which was the theme of the post-Crisis Superman mythos. This was reversed after 2003 when it was revealed that Superboy (Conner Kent) was half Kryptonian and then in 2004 when Supergirl (Kara Zor-El) arrived on Earth. The Eradicator did not place the planet-bound restrictions on the Krypton of the current DC universe but it still seems to be responsible for the Daxamites' lead vulnerability.

The Krypton of the current continuity was at one time an expanding empire that conquered other planets for years but was dismantled after the Kryptonian high council decided that their methods were too aggressive. The city of Kandor

Superman: The Movie

With the release of the first feature-length Superman movie in 1978, a vastly less idyllic image of Krypton, compared to the previous comics' versions, was presented. Whereas in the comics, Krypton was colorful and bright, in Superman, the planet was envisioned as having stark white terrain of jagged frozen plateaus, stretching broadly under heavy, dark skies (becoming redder as their sun grew toward becoming supernova

 to attempt to persuade the immediate evacuation of the entire planet to the council of elders, to avoid perishing in the cataclysm, to no avail.

Kryptonians themselves were portrayed as being a coolly cerebral society, clad in stark white body-suits emblazoned with the standard of each family's house symbol, and treading through halls of antiseptic, white crystal under crystalline arches. The crystalline motif was employed not only in the architecture, but in the landscape and technology as well, suggesting that the entire planet had been adapted and altered by Kryptonian influence. In 1948, Krypton was ultimately destroyed when its red sun began to collapse; the planet was pulled into the sun and steadily crushed, then exploded in the ensuing supernova. Krypton is mentioned in deleted scenes to be located in the (fictional) "Xeno Galaxy" and Jor-El's recordings say that Kal-El will pass through six galaxies during his three-year voyage to Earth. This could either mean Krypton is millions of lightyears away, well past the Andromeda Galaxy (making it the most remote of its various locations in any Superman story to date), or located in one of the dwarf galaxies

The explosion of Krypton was visualized through low-budget special effects and stock footage of simulated earthquakes. Of note is that the flight to Earth was depicted as occurring in a matter of seconds.

In the shooting script for the film (under the production title "Red Son"), Lex Luthor reveals to a weakened Superman that his henchman actually set Superman up to believe that Krypton still existed by sending false signals.

. In the new movie, Kryptonian crystals are able to grow huge land masses and incorporate the properties of the surrounding environment; a sliver taken from of one of the crystals used to test the theory causes Lex Luthor's basement to be filled with a huge crystal structure. Growing land in this manner causes widespread power failure in the vicinity, inadvertently causing the emergency involving a space-shuttle and an airliner which acts as Superman's triumphant return. When he later returns to the Fortress of Solitude to find that the crystals that powered it have been stolen, Superman is visibly enraged. Lex Luthor later combines one of the crystals with Kryptonite and shoots it into the ocean, creating what he calls "New Krypton". After being stabbed and falling into the sea, Superman uses his heat vision to get under the crust of the island and he then throws it into space, nearly killing himself in the process.
