A mesmerizing cosmic fantasy illustration of a mysterious fluffy black rabbit floating weightlessly through deep outer space. The rabbit is portrayed entirely as a dark silhouette with incredibly soft, long, voluminous fur that gently billows as if suspended in zero gravity. No facial features are visible except for two perfectly round glowing white eyes, creating an eerie yet adorable expression. Its head is slightly tilted toward the viewer, giving a curious, innocent, almost supernatural personality. The rabbit has exceptionally long upright ears extending elegantly upward, with subtle blue-violet highlights tracing their edges. One front paw is raised near its chest while the other rests naturally, creating a playful floating pose. The hind legs are loosely extended, and the fluffy tail curls softly behind, emphasizing the sensation of drifting effortlessly through space. The background is an expansive celestial nebula filled with luminous clouds of electric blue, indigo, deep violet, magenta, and hints of cyan. These colorful gases blend seamlessly like watercolor galaxies while maintaining brilliant contrast against the surrounding darkness. Thousands of tiny stars scatter across the composition with varying brightness and scale, adding immense depth. Several large radiant eight-pointed stars shine intensely throughout the scene, acting as focal points. Their crisp white glow softly blooms into surrounding shades of blue and purple, producing a magical dreamlike atmosphere. Thin curved light trails arc gracefully around the rabbit, suggesting orbital motion and enhancing the cosmic composition. The rabbit's silhouette is rim-lit with vibrant neon blues, violets, and pinks, allowing the fluffy fur texture to remain visible despite the nearly black body. The lighting creates an ethereal halo around the character, making it appear as though it is absorbing the colors of the galaxy itself. The overall composition is portrait-oriented, centered, and highly balanced with cinematic framing. The atmosphere feels peaceful, mysterious, whimsical, and enchanting rather than frightening. The image combines soft painterly digital brushwork with subtle glow effects, smooth gradients, and high-detail fur rendering. Every nebula cloud should appear luminous and rich in color, with seamless transitions between indigo, ultramarine, cyan, lavender, and magenta.
