Long-term observations have shown that a recurring radio burst emitted a unique glow caused by plasma from a nearby star. This suggests that the burst source is not isolated but part of a binary system. The discovery strengthens the argument that magnetars interacting with their companion stars can produce recurring cosmic rays.
For the first time, astronomers have detected radio signals from a rare exploding star, revealing what happened years before its death. The radio waves show that the star violently ejected a large amount of material before exploding, likely due to interactions with nearby stars.
The discovery gives scientists a new tool to turn back the clock and understand the deaths of stars. It also suggests that some supernovae have more dramatic final events than previously thought.
