Summary

Story summary

Astronomers identify GRB 230906A as a neutron star merger in a tiny galaxy 4.7 billion light-years away, via NASA's Fermi, Chandra, and Hubble.
The finding challenges view that such mergers occur only in larger galaxies and suggests the host formed from a gas stream created by ancient galaxy collisions.
It may address why GRBs appear away from dense centers and how heavy elements form in stars far from major galaxies.
