Comparison of Abell 370 in 2009 and 2016
This picture of the galaxy cluster Abell 370, compares the image of the cluster from 2009 and the new image — containing more data — from 2016. With additional observation time the depth of the image has been increased — making fainter and more distant objects visible in the final image.
The image released in 2009 was cut more than the new image, causing the dark corners.
