๐ญ A Supernova 'Chirped' โ and Astronomers Caught a Magnetar Being Born
For the first time ever, astronomers detected the birth of a magnetar through a strange chirping signal from supernova SN 2024afav, about a billion light-years away. The light oscillated and sped up โ just like gravitational waves from merging black holes โ caused by infalling material wobbling around the newborn neutron star at increasing speeds. It's also the first use of Einstein's general relativity to explain the mechanics of a supernova. How many more of these cosmic births are happening right now that we're missing?
