Sentences with phrase «radio bursts»
"Radio bursts" refers to short bursts of strong radio signals coming from space. These signals are often very quick, lasting only milliseconds, and are typically caused by powerful events such as black holes, supernovae, or neutron stars. Scientists study these bursts to learn more about the universe and its distant objects. Full definition
