Hubble Space Telescope investigations have shown that the brightest known fast radio burst originated from a cluster of old galaxies that seem to be merging.
Astronomers were taken aback by the discovery because single galaxies located significantly closer to Earth have been the source of the great majority of known fast radio bursts (FRBs).
The FRB in question was initially noticed by the Square Kilometer Array Pathfinder radio telescope in Western Australia on June 10, 2022, when it illuminated the radio sky above Earth.
Space media reports that although scientists are still unsure about the exact cause of FRBs, they believe there must be some sort of interaction between incredibly huge and compact objects, such as black holes or neutron stars.
The majority of FRBs that have been observed in the past can be linked to single, isolated galaxies.
However, the investigation into the origin of the extremely powerful event that was witnessed in June 2022 produced surprising findings. The venerable Hubble Space Telescope’s observations of the source location showed that the flash originated from a cluster of very old galaxies that appear to be merging, rather than from a single galaxy.
