Giant Space Tree Alien Ecosystem

The camera races along a branch of an impossibly large tree floating in space. The trunk is wider than continents and the branches stretch across entire star systems. Two flight craft weave through glowing leaves the size of cities while rivers of light flow through the bark like veins. The camera follows as they dive through hollow sections of the branch containing ecosystems, floating settlements, and glowing forests. A transparent observation chamber is embedded inside the tree itself, overlooking the flow of luminous sap through the structure. The craft spiral upward through the canopy and emerge above the branches where countless stars hang between the leaves.
