On December 27, 2004, a magnetar on the far side of the Milky Way unleashed more energy in a fifth of a second than the Sun will radiate across a quarter million years, and the pulse crossed tens of thousands of light-years to briefly disturb Earth's own ionosphere. The event forced scientists to reckon with instruments that could not survive what they were built to measure, and with the unsettling possibility that some of the universe's most dramatic explosions have been quietly misidentified in our catalogues. It is a reminder that the cosmos does not wait for our detectors to be ready, and
