Hubble's 'cosmic cobweb' image for Halloween features gravitational lensing in 4K

The NASA/ESA Hubble Space Telescope has imaged Abell 611, a galaxy cluster located about 3.2 billion light years from Earth. Gravitational lensing seen in the image makes it a good target to study dark matter, according to the Hubble team.
