Another night of observing begins at the U.S. National Science Foundation Cerro Tololo International Observatory (CTIO) in the Chilean Andes, a Program of NSF NOIRLab, as the Moon sets below the horizon. The Moon appears massive and with a mysterious yellowish glow as it retreats behind the SMARTS–GSU 0.9-meter Telescope on the left, the SMARTS–GSU 1.5-meter Telescope in the center, and the Víctor M. Blanco 4-meter Telescope on the right.

The Milky Way shares the stage with a luminous bubble of green and orange airglow in this panoramic image of Gemini North, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. Gemini North (right) is accompanied here by the Canada-France-Hawai‘i Telescope (CFHT) (left). In this image, you could remove all of the stars, the brilliant stripe of the Milky Way, and the nearby city lights of Hilo, Hawai‘i (far left), and you would still be left with a picture that isn’t completely dark. This is thanks to the persistent light of airglow.

Airglow is primarily caused by sunlight interacting with atoms and molecules in Earth’s upper atmosphere, which allows them to gain excess energy. This excess energy is then released as a particle of light called a photon. The frequencies of the photons determine the captivating colors of airglow. While it’s often difficult to see this light with the naked eye, a camera can capture it, as seen in the photo above. Intersecting the Milky Way is another lucent phenomenon known as zodiacal light with the gegenschein to the right.

This photo was taken as part of the NOIRLab 2022 Photo Expedition to all the NOIRLab sites. Petr Horálek, the photographer, is a NOIRLab Audiovisual Ambassador. Fulldome and extended view versions of this photo also are available.

This Image of the Week showcases the stunning Milky Way gracefully arcing over the NSF Víctor M. Blanco 4-meter Telescope at the U.S. National Science Foundation Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab in Chile. CTIO is located at an altitude of 2200 meters (7200 feet) in the remote mountains of Chile. This location, high in the sky and far from city light pollution, allows telescopes like the Blanco Telescope to study the sky in breathtaking clarity. This image encapsulates the beauty of the cosmos and the sophisticated efforts undertaken by astronomers to unravel its mysteries. One such effort in which this telescope has played a major role is the Dark Energy Survey (DES). The survey examined the origin of the accelerating Universe to uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion. Over a six-year period, this telescope, armed with the Dark Energy Camera (DECam) fabricated by the U.S. Department of Energy, observed about two million distant galaxies and found several thousand supernovae. The results of this ambitious survey are being used to trace the history of cosmic expansion and study the nature of dark energy.

A photography of the NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy (DOE) Office of Science, seen here on the low ridge of Cerro Pachón in Chile with snow-dusted mountains in the background. With an altitude of more than 2600 meters (8600 feet) at Rubin Observatory, Cerro Pachón is an ideal location for astronomical research with its dry, stable air. The 8.4-meter Simonyi Survey Telescope at Rubin Observatory, equipped with the LSST Camera — the largest digital camera in the world — will survey the entire southern hemisphere every few nights for a decade to create an ultra-wide ultra-high-definition time-lapse record of our Universe. This unique ‘movie’ will bring the night sky to life, yielding a treasure trove of discoveries.

Rubin is positioned near two other observatories in the foothills of the Chilean Andes: the Gemini South telescope, seen at upper-right, and the SOAR Telescope, the smaller telescope to Gemini’s left. Gemini South is one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab. The small dome directly to the right of Rubin is the Rubin Auxiliary Telescope (AuxTel), which will provide complementary data on the atmosphere above to assist Rubin’s observations of the Universe.

De Antlia cluster van sterrenstelsels is een groep van minstens 230 sterrenstelsels die door de zwaartekracht bij elkaar worden gehouden; het is een ongewone cluster want anders dan de meeste andere clusters lijkt er geen dominant sterrenstelsel te zijn.

De Antlia-cluster wordt gedomineerd door twee
