An worldwide team of researchers makes observations that defy our existing understanding, including the location of the source for deep-space rapid radio bursts and a changing, magnetic environment. The energy released by one fast radio burst (FRB), a millisecond-long cosmic explosion, is equal to the sun's annual output. More than 15 years after their initial discovery, deep-space pulses of electromagnetic radio waves still astound scientists with their puzzling nature. Recent research just adds to the enigma surrounding them.                                                                                               Unexpected new findings from a collection of cosmic radio bursts by an international team of researchers cast doubt on the convention...

A new research, published last month in the journal Nature Astronomy, shows that strong cosmic radio pulses from the deep cosmos may be utilized to analyze the gas cocooning closer galaxies. Fast radio bursts, or FRBs, are radio wave pulses that often come from distant galaxies that are millions to billions of light-years away. While electromagnetic energy, radio waves have lower frequencies and longer wavelengths than the visible light that we perceive with our eyes. Since the initial FRB was found in 2007, hundreds more have been found. A large FRB that erupted in the Milky Way galaxy in 2020 was discovered by Canada's CHIME experiment and Caltech's STARE2 instrument (Survey for Transient Astronomical Radio Emission 2). These previous discoveries contributed to the confirmation of the hypothesis that magnetars—dead, magnetized stars—are the most likely source of the explosive occurrences. Scientists are currently examining how FRBs may be utilized to examine the gas between E...
