A science fiction scene visualizing an ultra nuclear weapon in a galaxy far away. The weapon, colossal in size, with an outer shell adorned with glowing lines akin to circuitry, reflecting a menacing light. The galaxy around it, twinkling with a million stars, nebulae diffusing hues of blues and purples, creating an enigmatic background. Distant planets and celestial bodies are seen orbiting nearby stars, illuminating the vast expanse of cosmic space.
