NASA’s James Webb Space Telescope has identified the host galaxy of the most distant fast radio burst (FRB) detected to date.
NASA’s James Webb Space Telescope has identified the host galaxy of the most distant fast radio burst (FRB) detected to date.
The signal, FRB 20240304B, originated in a small, actively star-forming dwarf galaxy that existed just 3 billion years after the Big Bang. The discovery strengthens the theory that these mysterious millisecond-long radio flashes may originate from young, highly magnetized neutron stars called magnetars, rather than neutron star mergers.
