As the stars within the cluster interact with other clusters and clouds of gas in the galaxy around them, and as the gas between the stars is either used up to form new stars or blown away from the cluster, the cluster's structure begins to change.

The gravity of a galaxy cluster between Earth and PS1 - 10afx could warp space - time and, in effect, focus the supernova's light towards Earth.

In terms of mass they lie between the more commonly found stellar - mass and supermassive types of black hole [3], and could tell us about how black holes grow and evolve within clusters like Messier 15, and within galaxies.

If the lensing effect is strong, then multiple images of a distant galaxy will be produced and the separation angle between the multiple images gives us the mass of the lensing object (in this case, the closer galaxy or galaxy cluster).
