Solitary astronaut holding dandelion seed in colorful nebula

A lone astronaut adrift in a nebula, her helmet reflecting the cosmic dance of stardust and distant galaxies. She holds a single, delicate dandelion seed, a symbol of fragile life against the vast unknown. The style is a blend of hyperrealistic space photography and abstract expressionism, with swirling, vibrant colors of amethyst, sapphire, and emerald. The mood is one of profound solitude and cosmic wonder, capturing the breathtaking scale of the universe.
