South Africa’s MeerKAT array detected fast radio burst FRB 20240304B in March 2024. Researchers concluded that its signal traveled roughly 10.8 billion years, making it the most distant fast radio burst yet recorded.
The James Webb Space Telescope traced it to a dwarf galaxy where researchers estimate 90% of the stars formed within the last 30 million years. That is consistent with a newborn magnetar as the source, but does not establish what produced the burst. Distortions in the signal also led the team to infer a previously unknown galaxy group about 3.5 billion light-years away.
