COMPTEL produces maps of the aluminum-26 emission line produced in these events. The repeated cracking of magnetar crusts is responsible for these events in a model of their production. One of these events named 970508 was thought to be a variable star, but accurate optical observations of over three days showed a persistent X-ray signal which disproved that theory. That observation also placed the origin of these objects outside of the Milky Way, and was made by (*) BeppoSAX, which looked at the electromagnetic spectrum of their afterglow. These events may occur repeatedly from SGRs. These objects were originally discovered by the Vela satellites looking for radiation from Soviet nuclear tests. For 10 points, identify these astronomical explosions that release their namesake form of electromagnetic radiation more energetic than X-rays.
