New DarkBite! 🤩🌌Measurements of galaxy distance have uncertainty. This means our data are consistent with many possible variations of how galaxies are distributed. We use a method called Hyperrank to summarize those possibilities with just a few numbers. #darkbitesIllustration: Jessie MuirText: Ian HarrisonRead about this new Hyperrank method applied to the DES Year 3 data here: arxiv.org/abs/2109.09636 ...

The Dark Energy Survey

2 weeks ago

Timeline PhotosSeemingly adrift and alone in a field of stars, the spiral #galaxy #NGC1398 is the feature of this #ImageOfTheWeek. Upon closer inspection, one can see that the surrounding sky is actually teeming with the smudges and whirls of distant galaxies. NGC 1398 lies roughly 65 million light-years from Earth in the constellation Fornax. This deep portrait of NGC 1398 and its neighborhood was captured by the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO). The image was taken as part of the The Dark Energy Survey funded by the DOE (U.S. Department of Energy), with one of the highest-performance, wide-field CCD imagers in the world, DECam, built and tested at DOE’s Fermi National Accelerator Laboratory.Read more about this image on our website ow.ly/qEEg50GmDHQCredit: Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURAImage processing: T.A.

Timeline PhotosDo you like to explore breathtaking #astronomy images for interesting details? If so, check out this zoomable image of the Fornax #galaxy cluster from the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. Appearing in the constellation Fornax (the Furnace), the Fornax Cluster is relatively nearby at only about 60 million light-years from Earth. How many galaxies do you see? How many ring galaxies can you find in this image? Some foreground #stars, which belong to our own #MilkyWay Galaxy, appear in the image as well. Enjoy exploring all the stellar details of this beautiful image!

Timeline PhotosThe denizens of the Fornax galaxy cluster populate this image from the Dark Energy Camera located in Chile at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. In the bottom left corner of the image appears the irregular galaxy NGC 1427A, which is plunging toward the heart of the cluster at roughly 2.2 million kilometers (or 1.3 million miles) per hour. This headlong rush to destruction will eventually result in the galaxy being disrupted — pulled apart by gravitational interactions with other galaxies.This image was captured by the 570-megapixel Dark Energy Camera (DECam), one of the highest-performance, wide-field imagers in the world, as part of the Dark Energy Survey (DES). Funded by the US Department of Energy (DOE) and built and tested at DOE’s Fermilab, DECam was operated by DOE and the National Science Foundation (NSF) between 2013 and 2019. At present DECam is used for programs covering a huge range of science.Review the full photo release on NOIRLab’s website at noirlab.edu/public/news/noirlab2126/.#NOIRLab #DiscoverTogether @darkenergysurvey #DECam #NSFstories #FornaxClusterCredit: CTIO/NOIRLab/DOE/NSF/AURAAcknowledgment: Image processing: T.A.
