A mysterious sign from the universe
Three billion light-years away, astronomers say they are receiving a mysterious radio signal from another galaxy.
Scientists have explained that this signal is repeated in the same way. That has come as a surprise to scientists. The origin of the signal has not yet been revealed.
Astronomers have been able to capture the mysterious radio signal with the help of the giant Spiral Radio Wave Telescope in Guizhou Province, China.
