SSpace

A spiral galaxy, seen partly from the side, with a messy, turbulent appearance. Its disc is made of multiple patchy arms that contain numerous sparkling blue and glowing red regions — star clusters and star-forming nebulae. Thick clumps of dark reddish dust swirl through the disc. The glow of the disc extends out into the dark background, where both distant and nearby stars can be seen.

SSpace

A close-in view of a spiral galaxy that faces the viewer. Brightly lit spiral arms swing outward through the galaxy’s disk, starting from an elliptical region in its center. Thick strands of dark reddish dust spread across the disk, primarily along the spiral arms. The arms also contain many glowing, pink-red spots where stars form and clumps of bright-blue star clusters. Beyond its spiral arms, the galaxy is a bit fainter and speckled with blue stars.

A faint, slightly yellowish point of light—Comet 3I/ATLAS—appears near the center of a grainy, brown-toned background captured by the SOHO/LASCO C3 coronagraph between October 15–26, 2025. The comet is only marginally brighter than the surrounding noise, making it difficult to distinguish.

Hubble captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus.

SSpace

An oval-shaped spiral galaxy. Only the center and lower half of the galaxy is in frame. Its center is primarily golden in color with a white glowing core, while its thick spiral arms are mostly blue, particularly at the outskirts; these colors merge in between. Dark lanes of dust swirl through the center, blocking some of the galaxy’s light. Stars and distant galaxies are visible around the edges on a black background.

SSpace

A close-in view of the center of galaxy M82. Bright, bluish light radiating from the center is due to stars actively forming there. A thick lane of gas, black in the center and red around the edges, crosses the center and blocks much of the light. Thinner strands and clumps of reddish dust cover much of the rest of the view.

SSpace

$Stars in a star cluster shine brightly blue, with four-pointed diffraction spikes radiating from them. The center shows a small, crowded group of stars while a larger group is partially visible on the right side of the image. The nebula is mostly thick, smoky clouds of gas, lit up in blue tones by the stars. Clumps of dust hover before and around the stars; they are mostly dark but lit around their edges where the starlight erodes them.$
