Sol Gamma Wave

The Sol Gamma Wave disaster was by far the largest and most devastating disaster to ever befall Humanity, resulting in the destruction of Earth, the Human homeworld, precipating the Fall of the Earth Federation and resulting in a death toll that can only be estimated at around 78-billion.

History

The wave-front, observed from Altair 7-hours before contact.

Eruption

Occuring on 8 October 2601, the origin, cause or creator of the gamma radiation wave is unknown but its point of eruption is considered to have occurred somewhere within the orbit of Luna, Earth's sole moon. In the course of 63-minutes it destroyed all organic life in the area. Because of the intensity of the radiation, not even military-grade bunkers or shielding systems of the era could offer any protection.

Due to flucations in the gamma wave front, the exact time of the eruption can not be determined but the last out-system transmission out of the Sol-system was a personal message from Edith Grinder, a confirmed resident of Diplyon, a city on the Jupiter moon of Europa. No mention of the disaster was made during the letter, addressed to an unknown individual only referred to as Ting who resided in the Proxima Centauri-system.

Expansion

Traveling at a vastily impossible speed of one-light year per day, the dynamics of which are still unknown to contemporary science, it covered an area of 2389-square light years over the course of 6.5-years. 

Due to variations in wavefronts, as a result of impacts with stellar objects large enough to disrupt or absorb the energy, some solar systems received varying degrees of exposure. In total the immediate 180-square light years around Sol received near total exposure, while systems between 190 to 800-square light years outward received only 70% exposure, 810 to 1700-square light years outward received 45% exposure and systems between 1710 and the final disapating wavefront at 2389-square light years outward received only 10% exposure.

As defined at the time by Earth Federation records, the Core Colonies were those worlds that lay within 150-light years from Sol, while the much more moderately spaced Outer Colonies were those worlds between 200 and 2000-light years away and between 2000 to 5000-light years away were sparse and lightly populated Frontier.

The resulting wavefront meant the complete destruction of the most economically successful, high populated and stable Core Colonies, devastating but survivable damage done to the Outer Colonies and light, insignifcant damage to the Frontier. 

Below is a list of those worlds that suffered total or near-total destruction as a result of the Sol Gamma Wave:
