In 2016, astronomers detected one of the most distant and powerful Fast Radio Bursts (FRBs) ever recorded—coming from nearly 5 billion light-years away. To put that in perspective, when the signal began its cosmic journey, Earth itself didn’t even exist yet. While the true source remains unknown, scientists suspect extreme objects like magnetars, neutron star mergers, or even black hole activity. FRBs are milliseconds long, but carry more energy than our sun produces in days. The mystery continues—reminding us just how vast and ancient our universe truly is. #FastRadioBurst #SpaceMysteries #DeepSpace #CosmicSignals #Astrophysics #RadioAstronomy
