WASHINGTON : Powerful bursts of radio waves emanating from a distant dwarf galaxy that were detected using a massive telescope in China are moving scientists closer to solving what one called a"cosmic mystery" that has lingered for years.
Researchers on Wednesday said they have detected a fast radio burst, or FRB, originating from a dwarf galaxy located nearly 3 billion light-years from Earth. A light year is the distance light travels in a year - 5.9 trillion miles . This galaxy's collective star mass is roughly one-2,500th that of our Milky Way.
"Fast radio bursts are intense, brief flashes of radio light that are powerful enough to be seen from across the universe," added Caltech astronomer and study co-author Casey Law."The burst blinks on and off in about a millisecond, far faster than the blink of an eye. Some sources of FRBs have been found to emit multiple bursts in what look like storms of activity, but others have only been seen to burst once.
