Astronomers detected a scintillation arc in the spectrum of fast radio burst (FRB) for the first time using China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish and most sensitive radio telescope.
FRBs are mysterious radio flashes lasting only a few thousandths of a second that were confirmed in 2016 to originate from the cosmos. There is still no explanation for their origins.
The discovery opens up a new approach of examining at the medium of fast radio bursts and their possible orbital motion.
FAST started formal operation in January 2020, located in a naturally deep and round karst depression in Southwest China's Guizhou province. It is believed to be the world's most sensitive radio telescope. (QNA)
