This artist's impression represents small-scale concentrations of dark matter in the galaxy cluster MACSJ 1206. Astronomers measured the amount of gravitational lensing caused by this cluster to produce a detailed map of the distribution of dark matter in it.

Dark matter is the invisible glue that keeps stars bound together inside a galaxy and makes up the bulk of the matter in the Universe. ​​​​​​​
