Spoiler:

The vast Kryptonian powers that served to make him Superman also made Kal-El essentially immortal. He would watch as he out lived his parents, then his friends and then even his wife Lois. Still serving as the world's foremost champion he began to slow as the sadness of the losses began to mount. Legend then tells how close to the end of the twenty first century Superman Prime (as history will remember Kal-El) passed the responsibilities of being Superman to his heir, Superman Secundus, and created the Superman Dynasty. Then one day he left Earth.
His travels lasted from the 21st Century, and ended somewhere at the turn of the 700th Century. During his travels, he acquired vast abilities and skills from across the universe. When he returned he forged a covenant with his descendants, he would bestow upon them a small fraction of his power as long as they served for truth and justice. After the covenant he left and returned into his fortress of solitude in the center of the Super Sun.
When Solaris fired what he thought was the Knight Fragment at the Sun in order to kill Superman Prime, the Green Lantern retrieved a DNA sample from Solaris' core which had been placed there when he was constructed, starting a supernova reaction in Solaris' core. The Green Lantern then attempted to contain the explosion with his power ring. He was joined by Kal Kent who used his force vision to contain the explosion. Superman Prime suddenly reappeared from the sun after fifteen thousand years of absorbing solar energy and crushed the tyrant sun once and for all with the Green Lantern ring that Solaris had inadvertently given to him.
The time he spent in the sun magnified his already great power to presumably infinite levels. His strength and other countless abilities he gained also rose to unknown levels from the time he spent in the sun.
In the aftermath of Solaris' destruction a lot was revealed about Superman Prime's hibernation in the Super Sun. During this period, he had been waiting for Solaris' attempt on his life because he had foreknowledge of the events thanks to his time-traveling younger self. He knew about the DNA sample in Solaris' core and, with the help of Lzyxm Ltpkz (the Superman of the Fifth Dimension) and Hourman, used it to his advantage and, in the process, resurrected his beloved Lois Lane. After what seemed to him like an eternity, he had retreated into the sun to await her return and now a Silver Lois Lane and a Golden Superman Prime were reunited. In all the time since her death, life had held little meaning or warmth for him, but now Superman Prime felt he was complete once more.
