Composite image of Arp 26, also known as M101 or the Pinwheel Galaxy. It combines data from X-ray (Chandra, purple), infrared (Spitzer, red), visible light (Hubble, yellow), and ultraviolet (GALEX, blue) telescopes. Credit: NASA, CXC, SAO;NASA, JPL-Caltech;NASA, STScI Source
A multiwavelength image of a spiral galaxy. The galaxy has a small pink core. Several arms spiral clockwise around the core. They are crossed by pink, filamentary dust lanes and made of a haze of yellow stars. Along the arms are purple splotches. In the outer parts of the galaxy, the arms appear blue, dotted with blue star clusters. The arms are somewhat well-defined but asymmetric. One arm curls from about 6 o'clock to 9 o'clock and is mostly separated from the body of the galaxy. Other arms cover the area from 12 o'clock to 6 o'clock.

Hubble image of Arp 284, also known as NGC 7714 and NGC 7715. In this image of NGC 7714, we see a golden loop of of Sun-like stars created after a close encounter with its companion galaxy, NGC 7715 (out of frame), about 100 million years ago. Credit: NASA, ESA, A. Gal-Yam Source
The galaxy is offset on the left side of the frame. Its center is a bright white-blue. From the center extends a wispy tan spiral arm, first going toward the top and then circling counterclockwise before dissipating just below the center of the galaxy. Two bright blue spiral arms, dotted with whiter areas of star formation, follow a similar counterclockwise path, but the blue spiral arms end in thin, dim lines that extend to the left side of the image, going off frame, and toward the right. There are tiny red background galaxies along the top third of the frame, and one prominent foreground star toward the bottom third.

Blue points of light and a blue haze on a black background. The blue haze roughly corresponds to the location of the galaxy’s bar in images taken at other wavelengths. A series of bright blue points are at the center of the hazy structure.

New Technology Telescope image of Arp 271, also known as NGC 5426 and NGC 5427. The mutual gravitational interaction of this pair of spiral galaxies distorts their shapes and creates a bridge of gas, dust and young stars that connect the galaxies. Credit: ESO Source
Two similar-looking spiral galaxies take up most of the frame. They both have bright, yellow-white central cores and well-defined spiral arms dotted with blue star clusters and dark dust lanes. NGC 5427 is a nearly face-on spiral galaxy at lower left. NGC 5426 is a more oblique galaxy at upper right. The two spiral arms on the upper side of NGC 5426 appear as a bridge that connects with NGC 5427. The black background of space is dotted with stars and small background galaxies.

JWST and Hubble image of Arp 142, also known as NGC 2936 and NGC 2937, or the Penguin and the Egg. In Hubble’s visible light image (left) a dark brown dust lane crosses the Penguin. In Webb’s near-infrared view (right), this dust is fainter. Credit: NASA, ESA, CSA, STScI Source
Frame is split down the middle: Hubble’s visible light image at left, and Webb’s near-infrared image at right. Both show the Egg at left and the Penguin at right. In Hubble’s view, the Penguin is highly detailed, with a bright blue beak, body, and tail that is covered in an arc of bright brown dust. The Egg, to its left, appears bright, gleaming yellowish white. At top right is another galaxy seen from the side, about as long as the Egg’s height. Dozens of galaxies and stars appear in the background. Webb’s near-infrared image shows the Penguin’s beak, head, and back in shades of pink. It’s tail-like region is more diffuse, and a mix of lighter pinks and blues. The Egg appears slightly larger in blue layers. A semi-transparent blue forms an upside down U over top of both galaxies. At top right, an edge-on galaxy has many more pinpricks of light, which are stars. Thousands of galaxies and stars appear in the background. Some galaxies are shades of orange, while others are white.

Hubble image of Arp 321, also known as Hickson 40. This group of galaxies include three spiral galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Credit: NASA, ESA, STScI, Judy Schmidt Source
Five galaxies appear close to each other in the sky. At upper left, a spiral galaxy is tilted, appearing wider than it is tall. It has a glowing yellow-white center and brown dust trails that spiral clockwise around it. Above the center is a large elliptical galaxy. Its round, glowing yellow-white center is surrounded by a fuzzy halo that fades away from the core. Toward the bottom right are three galaxies that appear to touch. The largest is in the center: a nearly vertical, edge-on spiral galaxy. Its glowing yellow-white core is mostly obscured by reddish-brown dust trails dotted with blue stars. To its bottom left is a smaller, tilted spiral galaxy with a glowing white center. Brown dust trails are dotted with blue stars. One spiral arm appears to touch the vertical galaxy to its right. At the spiral’s bottom right is a lenticular galaxy with a glowing central core in the middle of a hazy white disk, appearing almost face-on. It seems to touch the large spiral galaxy above it.

Image shows a large spiral galaxy that has a bright white center, with several lanes of reddish-brown dust and gas in between faint white arms. The galaxy takes up the center third of the frame. There are several thousand stars, some with diffraction spikes, scattered around the image. This image is labeled Hubble. A small box outlining an area at the center of the galaxy leads to a pullout square at the top right. The image, labeled Webb, is dark with a white glowing oval at the center.

Even though Stephan’s Quintet is called a quintet, only four of the galaxies here are close together (about 290 million light-years away from Earth). The fifth and leftmost galaxy, NGC 7320, is only about 40 million light-years away: bit.ly/42MkBik 🔭 🧪
A group of five galaxies that appear close to each other in the sky: two in the middle, one toward the top, one to the upper left, and one toward the bottom. Four of the five appear to be touching. One is somewhat separated. The galaxies are large relative to the hundreds of much smaller (more distant) galaxies in the background. All five galaxies have bright white cores. Each has a slightly different size, shape, structure, and coloring. Scattered in front of the galaxies are number of foreground stars with bright white diffraction spikes radiating from the center.

The image is split in half vertically. On the left, a black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies, mostly the redder galaxies, are distorted, appearing to be stretched out or mirror imaged. Just a little bit above the center, there is a bright source of light, a star, with 8 bright diffraction spikes extending out from it. A portion of the larger image is zoomed-in on the right, showing a particularly long, red, thin line that stretches from 1 o’clock to 7 o’clock. There are several bright dots, some thicker than others, along this line, with one labeled as Earendel.
