Residing in the heart of a dwarf galaxy four billion light years away is a mysterious cosmological object producing bursts of energy that only last a few milliseconds. New research about this Fast Radio Burst (FRB) has revealed a rarely seen astronomical environment around its source, where magnetic fields twist, turn, and undulate over time. This is the first detection of a magnetic field reversal observed from an FRB, and the first time this behavior has been observed in another galaxy.(more…)
Looping Radio Signal Baffles Astronomers
Scientists have detected the first reliable radio signal pattern in space … The transmission broadcasts from a galaxy half a billion light years away. Can radio astronomy catch up and solve the mystery?

GBT Detects Super-Quiet Repeating Fast Radio Burst
Recently, the Green Bank Telescope (GBT) confirmed the detection of a repeating fast radio burst (FRB). The super-sensitive GBT was able to confirm that the radio burst from FRB 171019, initially detected by the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope, did repeat.
This detection lends credence to the theory that almost all fast radio bursts repeat, just very, very quietly.
