Researchers recently mapped out the magnetic field of the gargantuan galaxy cluster "El Gordo."
The resulting map of swirling magnetic field lines is the largest of its kind.
Galaxy clusters are the biggest structures in the universe that are bound by gravity. The cluster in question is El Gordo (Spanish for "the Fat One"), which is located around 7 billion light-years from Earth and contains hundreds of galaxies with a combined mass equivalent to more than 2 quadrillion suns.
