The universe's largest shockwaves is 60 times larger than the Milky Way - Universe Today by AndyTomaswick
, and it always seems like they are trying to one-up themselves in finding a bigger, brighter one. There’s a new entrant to that category – an event so big it created a burst of particles over 1 billion years ago that is still visible today and is 60 times bigger than the entire Milky Way.to create a supercluster known as Abell 3667.
Picture of galaxy cluster Abell 3667, where the white color in the center is a concatenation of 550 distinct galaxies, but the red structures represent the shockwaves formed during the creation of this supercluster.Those radio waves are what Dr. de Gasperin and his colleagues observed using a new telescope array in South Africa known as MeerKAT.
The results of all those observations is a better understanding of the physics of the merger of these galaxy clusters, which were “much more complex than we initially thought,” said Dr. de Gasperin. The shockwaves themselves look like “filaments that trace the location of giant magnetic field lines.” What is clear from the pictures is that, even when scientists are simply looking for big collisions, the resulting radio images might be awe-inspiring in themselves.
