A recently discovered repeating fast radio burst (FRB) named FRB 20200120E is deepening the mystery of these already deeply mysterious space signals.
called M81, although with a degree of uncertainty. More specifically, the researchers believed they had tracked FRB 20200120E to a globular cluster.Here's why that's a problem. Globular clusters are compact groups of stars that tend to be very old and long-lived, as well as low mass,. All their stars are thought to have formed from the same cloud of gas at the same time; just like a small town, these stars then live out their mostly quiet existences together.
"Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster," the researchers"Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova."Every now and again, a globular cluster has been found to host a type of rapidly rotating neutron star known as a millisecond pulsar.
