ALT A starfield filled with thousands of stars and shining clouds of dust. The Milky Way\u2019s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Spanning more than 100,000 light-years, Earth is located along one of the galaxy\u2019s spiral arms, about halfway from the center. Credit: NASA

ALT A Webb image of many glowing galaxies in deep space, in various shapes and colours, on a black background. There are some large, blue spiral galaxies, some large and pale white elliptical galaxies, and many orange and red, medium-sized galaxies. Even smaller galaxies, down to tiny faint spots, appear in all these colours.

ALT A wide-field image of IRAS 16594-4656 taken by the James Webb Space Telescope. The nebula’s bright core is split by a narrow dark band, with expansive rainbow lobes of light and color radiating outward. Numerous background galaxies and stars are visible across the field.

ALT Image description: Modified version of a previous, popular artist illustration of the TRAPPIST-1 star system. The background is black. At far left is a representation of the TRAPPIST-1 star, an M class dwarf star. It is seen as a glowing orange-yellow semi-circle. To the right of the star, illustrations of its seven planets. The planets are labeled b, c, d, e, f, g and h.They all resemble mottled clay marbles in browns and dark greens. The planet TRAPPIST-1 d, which is the third one from the star, has been spotlighted to stand out. The other planets are dimmed down to be less visible. The planet d also has a white label as opposed to gray letter labels for the rest of the planets. At bottom right is the word “Illustration (2018)” in tiny gray text.
