$A section of the Cat’s Paw Nebula, a local star-forming region composed of gas, dust, and young stars. Toward the center is a large arch of brown-orange filaments of dust. The area to the left and right of this section appear darker and seemingly vacant of stars. Many small, yellow-white stars are spread across the scene, some with eight-pointed diffraction spikes that are characteristic of Webb. A few larger blue-white stars with diffraction spikes are scattered throughout, with the largest located at left.$
