Recently, astronomers used radio observations to detect the remnants of a powerful supernova explosion that occurred in a nearby galaxy. This is the first time that a supernova has been detected using only radio imaging, and it provides new insight into the evolution of stars and the structure of the interstellar medium. The supernova remnant, named SN2019dge, is located in the nearby galaxy M83, which is about 15 million light-years away from Earth. The radio emission from the supernova was detected by the Karl G. Jansky Very Large Array (VLA) in New Mexico. The VLA is a powerful radio telescope that can detect faint radio signals from astronomical objects. This discovery is particularly exciting for astronomers, as it shows that powerful supernovae like SN2019dge can be detected with radio telescopes, and can provide valuable information about the evolution of stars and the structure of the interstellar medium.
