Story summary

On March 16, 2025, astronomers identified the brightest fast radio burst (FRB) named RBFLOAT, located 130 million light-years away in galaxy NGC 4141.
The burst emitted energy comparable to the Sun's output over four days and was initially misidentified as interference.
CHIME's Outrigger system improved detection, enabling precise localization and insights into potential magnetar origins.
This discovery represents a significant advancement in FRB research and future cosmic studies.
