This image shows the galaxy MCS J0416.1-2403, one of six clusters targeted by the Hubble Frontier Fields programme.

The varying intensity of blue haze in this image is a mass map created by using new Hubble observations combined with the magnifying power of a process known as gravitational lensing.

Strong lensing gives a much more precise indication of the mass at the cluster's core whilst weak lensing provides valuable information about the mass surrounding the cluster core.
