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 ...

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!
