Meet the barred spiral galaxy NGC 5068 and the spiral galaxy NGC 1087. In both images, Webb's infrared vision illuminates numerous stars among clouds of dust and gas.
Image Caption:
1. Webb's near-infrared image of the barred spiral galaxy NGC 5068, showing its nucleus and part of its spiral arm. Thousands of small stars, visible as white spots, fill the frame. The stars are most dense in the whitish bar that forms the nucleus, with their density decreasing as we move from there towards the arm. Clouds of gas, shown in bright red, follow the curvature of the galaxy and the spiral arm.
2. Webb's image of NGC 1087 shows a densely populated face-on spiral galaxy fixed by its central region, which takes the form of a short light yellow line about one-fifth of the galaxy's length. Filamentary spiral arms of stars, gas and dust start from the centre, rotate clockwise and extend to the upper and lower edges. There is so much light in this region that the spiral arms of the galaxy appear blurred. They are largely orange-gold in colour. There are some bright blue points of light scattered throughout the filled scene, but they appear clearer in areas that are dark grey or black. Several small "bubbles" appear throughout the galaxy, which are black. The edges of the scene are dark black and there are some larger bright blue points of light, with a few pink shapes, which are probably background galaxies.
