A cloudy disk-like structure is forming in the left, bottom corner with a star at its center. There are jets of light coming from below and above the star with a string-like, spiraling structure surrounding the jets. The spiral structure is stretched out as it begins just above and below the star, then transitions to consistent ring-like turns as it moves farther from the star. There is another star/disk/jet indicated in the distance at the top right corner. These two structures are in a dense, cloudy atmosphere with glimpses of a star field in breaks of the clouds.

This illustration traces the universe’s evolution from the Big Bang to the present day, highlighting REBELS-25, a very distant galaxy seen during the Epoch of Reionization 13 billion years ago. New deep observations with the NSF VLA and ALMA reveal that REBELS-25 already had an enormous reservoir of cool molecular gas—the direct fuel for star formation—when the universe was just 700 million years old.

A bright, icy-looking object floats in deep space at the center of the image, surrounded by a large, glowing blue and pale orange cloud that fades softly into the dark background. The blue part of the cloud is largest and mostly on the left-hand side. The orange part is smaller and on the right-hand side. Small stars are scattered throughout the black sky.

Artist’s illustration of the binary star system WR 112. A bright blue-white Wolf-Rayet star and a nearby, smaller companion star orbit each other in space. Their powerful stellar winds collide between them, creating a glowing region where dust forms and streams outward in a spiral plume. A magnified inset in the top right corner, shows the dust grains against a reddish background, highlighting mostly extremely tiny, nanometer-sized particles along with a smaller number of grains about 100 times larger.

View of the Milky Way Galaxy seen from the ALMA Array Operations Site (AOS). The AOS is located on the Chajnantor plateau of the Chilean Andes, at an altitude of 5000 meters, making it the second highest building in the world. Light from the galaxy core shines even more brightly when captured at an altitude of 5000 meters – with so much less atmosphere to penetrate. ALMA Looks at the Milky Way
The astro-modified camera used to take this photo lets in the hydrogen alpha light that is normally filtered out. This modification makes the camera more sensitive to the red end of the electromagnetic spectrum, thus giving a pink tint to the sky. Green ALMA, Pink Milky Way
The red light at the top of the holography tower backlights the ALMA sign at the Operations Support Facility (OSF) while the core of the Milky Way Galaxy stands watch. The holography system is used to precisely calibrate the surface of the ALMA antennas. Milky Way Galaxy and Holography Tower at ALMA OSF
