This image from the NASA/ESA Hubble Space Telescope shows ACT-CLJ0102-4915. Massive galaxy clusters such as ACT-CLJ0102-4915 are useful tools for studying very distant objects, because this lens-like behavior amplifies the light from faraway galaxies in the background. They also contribute to a range of topics in cosmology, as the precise nature of the lensed images encapsulates information about the properties of spacetime, the expansion of the cosmos and the distribution of dark matter within the cluster.
