Artist impression of WR 112

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.

Artist’s impression of WR 112, a binary system containing a massive, evolved Wolf-Rayet star and an OB-type companion. As their stellar winds collide, dust forms and spirals outward, consisting mostly of extremely tiny, nanometer-sized grains along with a secondary population about 100 times larger.

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.

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.

The Milky Way Galaxy pours into an ALMA antenna. 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. The green lights are used to show antenna activity.

ALMA and Pink Milky Way

The Milky Way Galaxy stretches over ALMA and the Chajnantor plateau of the Chilean Andes. The Large and Small Magellanic Clouds can also be seen in this panorama that was stitched together from multiple photos.

Outside the ALMA Operations Support Facility (OSF), the second highest building in the world, fixtures are used sparingly to prevent light pollution from contaminating the incredible night sky. You can imagine that none of the stars in this photograph would have been visible if this light were on.
