Hubble Unveils Dark Matter Web in Stunning Abell 209 Galaxy Cluster Image
NASA/ESA’s Hubble Space Telescope has released a stunning new image of Abell 209, a massive galaxy cluster 2.8 billion light-years away in Cetus. The golden cluster houses over 100 galaxies, but beneath them lies an invisible web of hot gas and dark matter. Using gravitational lensing, Hubble reveals curved arcs of light from background galaxies, helping astronomers map unseen mass. The image—taken with Hubble’s ACS and WFC3 cameras—blends optical and infrared views, offering sharp cosmic detail. The findings aid our understanding of dark matter, dark energy, and how the universe evolves under their influence.
