The galaxy cluster Abell 3754 is captured here by the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam) on the Víctor M. Blanco 4-meter Telescope, one of around 40 telescopes at the U.S. National Science Foundation Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab.

Located about 200 million light-years away, Abell 3754 is a gravitationally-bound group of hundreds of galaxies. Galaxy clusters are the second-largest-scale structures known in the Universe, but even at their massive scale these galaxies are never all that far from each other. In the top left, the large galaxy IC 4329, surrounded by rings of light, shows evidence of a past cosmic collision. The spread-out fragments of illuminated blue and white gas on the right side of the image are evidence of a similar clash with the galaxy NGC 5291 (yellow color). If you look closely, you can see more evidence of gravitationally interacting galaxies.

DECam legt intraclusterlicht vast in sterrenstelselcluster Abell 3667

Intracluster licht is een diffuse gloed van sterren die tijdens de vorming van een sterrenstelselcluster uit sterrenstelsels zijn gestript.

Abell 3667 is te zien op deze DECam-afbeelding

A cosmic bloom in Monoceros. This glowing nebula spans 100 light-years and cradles young stars in its heart. Captured in vivid detail by DECam in Chile.

A vibrant wide-field astrophotograph of the Rosette Nebula (NGC 2237), appearing like a cosmic flower. The nebula glows with deep reds and pinks, surrounded by filaments of dust and gas. In its center lies a star cluster, NGC 2244, whose young blue-white stars illuminate the nebula. The entire structure is framed by the dark backdrop of space, with scattered stars dotting the field.

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.

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.

Cradled within the fiery petals of the Rosette Nebula is NGC 2244, the young star cluster which it nurtured. The cluster’s stars light up the nebula in vibrant hues of red, gold and purple, and opaque towers of dust rise from the billowing clouds around its excavated core.

DECam zoomt in op Antlia-cluster

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
