An illustration of the red supergiant star Betelgeuse, its companion star, and a dusty wake. The disk of a red-orange star is in the center. It is surrounded by a diffuse orange cloud representing its extended atmosphere. Below it about one stellar diameter away is a yellow dot representing a smaller companion star. From the companion, a dark red cloud wraps around in a counterclockwise direction. It begins very narrow and expands as it gets further from the companion, finally disappearing at the outer edge of the diffuse orange cloud around 10 ou2019clock. The words u201cartistu2019s conceptu201d are at lower right.

$Near the center is an object that resembles an edge-on view of a hamburger. There is a diagonal dark strip (the meat patty) of dust, running from 1 o'clock to 7 o'clock, that obscures a central star. Curving away from either side of the dark strip are glowing white clouds (the buns) where dust is reflecting starlight. Bright blue finger-like wisps of material extend far above and below the dark center plane. A few dozen stars, some with four diffraction spikes, are scattered on the black background of space.$

SSpace

A nearly edge-on spiral galaxy. Its disk holds pink light from star-forming nebulae and blue light from clusters of hot stars. Thick dark clouds of dust block the strong white light from galaxy’s center. A faint, glowing halo of gas surrounds the disk, fading into the black background of space. A bluish plume of gas also extends from the galaxy’s core extending toward the lower-right corner of the image.

SSpace

A pale blue dwarf galaxy on the black backdrop of space with some faraway galaxies. The galaxy itself resembles a fuzzy cloud of tightly packed stars, with a broad halo of stars dispersed around it. Spread across the galaxy’s core are several small, glowing patches of gas where there is a concentration of very hot stars.

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.

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.

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.
