Design a highly detailed, 16k resolution coin featuring the head of an extraterrestrial being at the center. The alien has large, almond-shaped eyes, a smooth elongated skull, and defined facial features, all illustrated in high contrast black and white. The background of the coin, behind the alien’s head, should display a detailed map of the galaxy, with stars and nebulae clearly visible. The design should have a strong contrast between the black and white elements, with no distortions, ensuring all lines are crisp and clear
