Create a stylized scientific illustration showing an astronaut during spacewalk with cosmic background. Near the astronaut's helmet visor, add a small visual of searing steak and metal welding sparks. Use a color palette of deep purples for space, warm reds for steak, and metallic grays. Add subtle particle effects representing polycyclic aromatic hydrocarbons as small glowing specks. Keep the style semi-realistic but slightly artistic to represent the abstract concept of smell. Include small stars in background. Composition should be portrait-oriented for mobile display with room for text overlay at bottom.
