This long exposure photograph taken by NASA astronaut Matthew Dominick with a camera programmed for high sensitivity shows star trails and streaks of city lights as the International Space Station orbited 258 miles above the South China Sea off the coast of Vietnam near Ho Chi Minh City.
[Image description: A pair of interacting galaxies. The larger of the two galaxies is slightly right of centre, and is composed of a hazy, bright, white centre and a ring of gaseous filaments, which are different shades of red and orange. Toward the bottom left and bottom right of the ring are filaments of gas spiralling inward toward the core. At the top left of the ring is a noticeable gap, bordered by two large, orange pockets of dust and gas. The smaller galaxy is made of hazy and white gas and dust, which become more diffuse further away from its centre. To this galaxy’s bottom left, there is a smaller, more diffuse gas cloud that wafts outward toward the edges of the image. Many red, orange, and white galaxies are spread throughout, with some being hazier in appearance and others having more defined spiral patterns.]
[Image description: At centre is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene, though there are patches and a noticeable gap in the top left corner that reveal the black background of space. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin discs. There is one noticeably larger blue-white point with diffraction spikes, a foreground star in the upper right.]
[Image Description: A nebula made up of cloudy gas and dust in the form of soft and wispy clouds and, in the centre, thin and highly detailed layers pressed close together. Large, bright stars surrounded by six long points of light are dotted over the image, as well as some small, point-like stars embedded in the clouds. The clouds are lit up in blue close to the stars; orange colours show clouds that glow in infrared light.]

[Image description: 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.]

[Image Description: A small image of a galaxy distorted by gravitational lensing into a dim ring. At the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other: these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens. In the centre of the ring, the elliptical galaxy doing the lensing appears as a small blue dot. The background is black and empty.]
[Image description: A growing protostar embedded within a molecular cloud. The center of the image shows a bright, red region, where the growing protostar resides, with a thin, gray lane of matter cutting through it horizontally, which is the protostar’s accretion disk. Above and below this region are blue triangular-shaped molecular clouds, which give the overall object an hourglass shape. The areas in the molecular clouds closest to the protostar have more pronounced plumes of blue gas. There are red, yellow, orange, blue, and green stars and galaxies scattered across the background.]
[Image description: A field of galaxies on the black background of space. In the middle is a collection of dozens of yellowish galaxies that form a foreground galaxy cluster. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the centre of the image. The linear features are created when the light of a background galaxy is bent and magnified through gravitational lensing. A variety of brightly coloured, red and blue galaxies of various shapes are scattered across the image, making it feel densely populated.]

*[Image description: This image shows two panels. On the right is field of many galaxies on the black background of space, known as the galaxy cluster SPT-CL J0615−5746. On the left is a callout image from a portion of this galaxy cluster showing two distinct lensed galaxies. The Cosmic Gems arc is shown with several galaxy clusters.]
[Image description: A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust and within that orange dust are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The centre of the image is filled with mostly blue gas. At the centre, there is one particularly bright star that has an hourglass shadow above and below it. To the right of that is what looks like a vertical eye-shaped crevice with a bright star at the centre. The gas to the right of the crevice is a darker orange.]
