Another cosmic mystery
First detected in 2007, rapid bursts of radio (FRB) are a mystery that astronomers have struggled to solve. On June 8, Reuters the researchers reported that they had detected an FRB from a dwarf galaxy nearly 3 billion light-years from Earth. A light year, he adds, is the distance light travels in a year: 9.5 trillion kilometers. The collective stellar mass of this galaxy is about 2,500 parts of that of our Milky Way. Scientists say this FRB is a recurring one that is always kept “on” and was detected by a massive telescope in China, the report adds. Could this offer solve the mystery?
