A planet- sized jellyfish floats in the upper atmosphere of a gas giant, its bell a transparent geodesic sphere containing a suspended city. The city hangs upside- down from the dome's apex, its skyscrapers reaching toward the planet below like stalactites. The jellyfish's tentacles are kilometers- long space elevators, ferrying materials from the planet's lower atmosphere. Bioluminescent patterns ripple across the bell's surface, serving as a complex communication network. Clusters of sensors and antennae sprout from the top of the dome, monitoring atmospheric conditions. Pods of smaller jellyfish- like structures orbit the main body, acting as outlying research stations. View from below, looking up through the gas giant's colorful cloud layers. Surrealist digital matte painting style with a vibrant palette of atmospheric oranges and pinks contrasting with the cool blues and greens of the jellyfish- city
