This detailed image features Abell 3827, a galaxy cluster that offers a wealth of exciting possibilities for study. Hubble observed it in order to study dark matter, which is one of the greatest puzzles cosmologists face today. The science team used Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 to complete their observations. The two cameras have different specifications and can observe different parts of the electromagnetic spectrum, so using them both allowed the astronomers to collect more complete information. Hubble also observed Abell 3827 previously because of the interesting gravitational lens at its core.
