The origin(s) of fast radio bursts remains a mystery.
Two classes of FRBs are known -- sources which
repeat, and sources which appear to be a one-off event.
ASKAP has successfully localised a number of one-off FRBs,
and other telescopes have pinpointed the location of
repeating FRBs.
Yesterday's ADAP described the work of Mannings et al.
based on Hubble Space Telescope observations of
FRB host galaxies.
This work was described in
this NASA press release
with the image above being a still from a video included in the release.
