Galaxy Projection in a Modern University Atrium

A hyper-realistic 3D render of a luminous galaxy hologram suspended in a modern university atrium. The spiral arms glow with blue, cyan, and magenta hues, dust lanes shimmering with star birth. Volumetric fog and soft lens flares create depth as students and faculty in smart casual attire look up, some taking notes on tablets. The atrium features glass walls, steel beams, and a polished marble floor with reflections, digital info screens; skylight above allows daylight to mix with the neon galaxy glow, giving a futuristic academic mood. High detail, cinematic lighting, depth of field, photorealistic textures, and subtle motion to imply movement in the galaxy.
