ALT Two interacting galaxies known as Arp 142. At left is NGC 2937, nicknamed the Egg for its appearance. At right is NGC 2936, nicknamed the Penguin for its appearance. The latter’s beak-like region points toward and above the Egg.
ALT Nineteen Webb images of face-on spiral galaxies are combined in a mosaic, some within squares, and others horizontal or vertical rectangles. Galaxies’ spiral arms appear in shades of orange, and many of their centres have light blue hazes.
ALT A graphic with three images. The top image, labelled “CEERS survey”, shows many square images of stars and galaxies, stitched together according to their locations in the sky. One square is highlighted, and a cutout on the bottom left shows it enlarged, labelled “Webb/ NIRCam”. A tiny spot is shown zoomed-in to the right, labelled “EGSY8p7” with a scale marker of “0.5 arcsec”. Here it can be seen that the spot is three neighbouring galaxies, appearing as coloured blobs with bright, distinct cores.
ALT A collage of all five Euclid images showing: the Perseus Cluster of galaxies, spiral galaxy IC 342, irregular galaxy NGC 6822, globular cluster NGC 6397 and the Horsehead Nebula
ALT An image of a young star-forming region filled with wispy blue, grey, green, and red nebulosity that is brightest towards the centre and fainter towards the edges, especially in the top left corner and on the right side. Thousands of stars are seen sprinkled across the field, concentrated towards the centre, and the brightest stars show the eight spikes due to diffraction that are characteristic of Webb images.
ALT An image of a young star-forming region filled with with wispy purple, green, and red nebulosity. The purple ionised gas is seen mostly towards the centre, with browns, greens, and reds behind, while the periphery is mostly bright green and darker brown to the left. There is a large spray of yellow, orange, red, and purple towards the top centre, and the nebula fades to near black to the right. There are thousands of stars sprinkled across the field, concentrated towards the centre, but they generally appear fainter at longer wavelengths, with some exceptions. The brightest sources in the field have extensive diffraction spikes characteristic of Webb.
ALT At the centre is a thin horizontal orange cloud tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thin at the opposite angle. At its centre is a set of very large red and pink diffraction spikes in Webb’s familiar eight-pointed pattern. It has a central yellow-white blob, which hides two tightly orbiting stars. The background is filled with stars and galaxies.
