Rula Tun-Kali [Gliese 876 c]

Orbiting a dim red dwarf about 15 light-years from Earth, Rula Tun-Kali shares its system with several planets whose strong gravitational interactions keep their orbits in constant motion. The planet has a very small orbit, circling its star at 0.13 AU, roughly one-third of Mercury’s distance from the Sun. However, since the star’s heat is […]

Jovian Bat

When the first microbial extremophiles were sent to Jupiter on automated probes, the goal was to test how life could adapt to extreme environments. Scientists built in genetic triggers: molecular switches that sped up mutation and guided adaptation under stress. They wanted to watch evolution happen quickly. The results went far beyond what anyone expected. […]

The Bell Maw

A name long whispered in sailors’ legends — a creature said to swallow ships whole in the black of a storm. For centuries, it was hearsay, a phantom blamed when wreckage vanished without a trace. But now, the myth has started to look real. The Bell Maw is among the largest discovered invertebrates on Installation […]

The Arch

It has been approximately 5 years since the silence. It’s late evening by the beach. The wind is calm but still manages to sway the dune grass in subtle coercion. Crickets chirp with the calm artificial waves, generated by a mechanical seawall some twenty miles out. Their peaks are what remain visible as the sun […]

Arbozoa

Arbozoa is a phylum of sessile, photosynthetic organisms unique to Garmiwala, serving as the planet’s tree-analogs. However, what sets the Arbozoa apart from plants is its animalistic larval stage. In its adult form, the Garmiwala resembles a terrestrial tree: a rooted structure with branching photosynthetic fronds, bark-like layers, and deep anchoring roots. Unlike plants, however, […]

Frost Bun

On the planet Rogue, the frost bun (Lepulima glacies) can be found tethered on the icy surface, spending most of its life motionless. It anchors itself with keratin-like hooks that grip the frozen surface, while it feeds through a partnership with chlorophyll-producing bacteria that cluster at the tips of its scaled exoskeleton. Instead of foraging […]

Usmani’s Law of Universal Morality

Also known as the “Cooperative Filter,” it states that for any species to become advanced enough to be a space-faring civilization, it must “play nice” — that is, develop mechanisms of long-term cooperation and trust. Technological and societal complexity require increasingly complex but stable institutions, which only function when there are diminished incentives and opportunities […]

Sea Pancake

When the rains finally hit Garmiwala, the environment fully transforms. Dust turns to mud, dry basins fill with water, and a hidden ecosystem kicks into motion. Filter feeders crawl out from the cracked ground and floodplains, drawn by the temporary lakes that only last a few weeks. A most recent discovery has been the sea […]

Tectonid

On the world of Gepara, there resides an eusocial species along the planet’s tropical mountain ranges. On the map below, the red dots indicate the location of multiple colonies. They live in the lush jungle areas where food is plentiful but competition is high. Because they live in fortified colonies within the mountains, the males […]
