A Rare Repeating Fast Radio Burst Gives Astronomers a Chance to Study These Mysterious Objects universetoday storybywill
in Hawaii showed that this placed it in the outskirts of a dwarf galaxy nearly 3 billion light-years from Earth.
“These characteristics make this one look a lot like the very first FRB whose position was determined — also by the VLA — back in 2016,” she said. “Now we have two like this, and that brings up some important questions.” The differences between these two sources and all others detected to date strengthen the possibility that there may be two distinct types of FRBs, something astronomers have long suspected.The team proposed that these results could indicate one of two things.

For one, it demonstrates that repeating bursts could be characteristic of younger neutron stars and that these FRBs dwindle with age as the gas and dust clouds surrounding them dissipate. Second, it raises questions about how useful FRBs could be in determining the distances between celestial objects and the density of the space between them.
