Create an image of the Sagittarius zodiac sign featuring a powerful centaur arch

Create an image of the Sagittarius zodiac sign featuring a powerful centaur archer. The centaur should be muscular, with flowing hair, holding a drawn bow aimed at the stars. The background should be a cosmic space scene, filled with galaxies, nebulae, and twinkling stars. The color palette should blend deep blues, purples, and starry whites, capturing the mystic and epic nature of the Sagittarius sign.
