Astronomers have discovered a new and unusual population of exploding stars. In fact, they've found that these stars "switch off" their radio transmissions before collapsing into a black hole. The findings reveal a little bit more about these strange stars which could help inform future studies.
Exploding stars use all of their energy to emit one last strong beam of highly energetic radiation, known as a gamma-ray burst. Until now, researchers believed that all gamma-ray bursts were followed by a radio afterglow. Yet this appears to not always be the case.
