Stars Edge Redux
The solar system was formed billions of years ago through the accretion of material remaining from the formation of its star, Sol, the sun. Locked ever since in its orbit, the history and present disposition of virtually every object within two light years is shaped by its relationship to this body. The sun is a bright G2 main sequence star, theoretically on the hot end of the continuum of stars able to give rise to life. For most of its history, transhumanity fueled its rises and falls with the sun’s energy, rst as stored in materials like hydrocarbons, later directly with solar converters.
Today the sun remains a crucial source of energy, but its outer reaches may also become home to some. The adaptations required to dwell here make these suryas one of transhumanity’s most unusual potential offshoots.
Habitats in Sol’s corona face challenges more extreme than those faced by habs anywhere else in the system. Transhumanity’s only means of shielding a habitat from the heat and radiation emitted by a G2 star is to generate strong electromagnetic elds. Even then, the dangers posed by solar ares and coronal mass ejections—massive explosions that jettison coronal material tens of thousands of kilometers out into circumsolar space—mean that the Sun’s polar regions are the only safe space in which to position habitats. As such, circumsolar habs require extraordinary expense to build and maintain, and two of the three major circumsolar habitats are heavily backed by distant organizations.
The outer layers of circumsolar habitats are covered with thousands of electromagnetic dynamos drawing power from the sun itself. These dynamos generate the powerful elds necessary for shielding. Within are intermediate layers lled with liquid water that captures ionized particles, teeming with nanites that collect the ions and vent them into space. The water must be regularly replaced from captured iceteroids that are imported using heavy electromagnetic shielding of their own. Within the water shield is a cluster habitat, an array of modules on a framework following a roughly spherical plan.
Coronal habitats are easily detectable at a great distance because of the bow shock preceding them and the plasma tail left behind in the solar wind.
