Galaxy cluster's magnetic field reconstructed for 1st time with record-breaking astronomy map

For the first time, astronomers have reconstructed the magnetic field of an entire cluster of galaxies, from its central nucleus to its outer limits. The record-breaking achievement is the product of the deepest-ever observations of the galaxy cluster Abell 2255, located around a billion light-years away — and those observations are thanks to the European radio telescope LOFAR (Low Frequency Array). Abell 2255 has long been known for its complexity in radio waves. Its vast, diffuse radio e
