Ákroterra
Extreme Earth
Dr. Penny Boston
Ákroterra is a cold, high-radiation planet nicknamed “Extreme Earth,”
blanketed by a swirling, nitrogen-rich atmosphere. Its surface gravity is
half that of Earth’s, creating an environment where geological and biological
forces behave in unexpected ways.
Beneath its radioactive-rich crust, thermal energy seeps upwards into
subsurface regions derived from radioactive decay of core radioactive elements
and tidal flexure caused by resonance of Ákroterra with its gas giant parent.
These special circumstances have shaped unique habitats where life has adapted
to a variety of inhospitable conditions. Like organisms that flourish in Earth’s
most extreme ecosystems, Ákroterra’s cave-dwelling organisms incorporate some
features of Earthly slime molds and fungi—adapted to radiation and geological
flux—and thus demonstrate life’s resilience and ingenuity.
If life thrives here, it may redefine our understanding of biochemistry and
intelligence, proving that even the most hostile planetary environments can
foster radically different living systems.
