๐ซ Astronomers Watched a Magnetar Being Born for the First Time โ Via a Supernova's 'Chirp'
A supernova 1 billion light-years away โ SN 2024afav โ didn't fade like normal supernovae do. Instead it pulsed four times with shrinking intervals, producing a distinctive 'chirp' in its light curve. UC Berkeley researchers say this is the first direct observation of a magnetar forming: a neutron star spinning 240 times per second with a magnetic field 300 trillion times stronger than Earth's. The discovery confirms a theory proposed 16 years ago and defines a brand new class of stellar explosion. Which long-standing space theory are you most hoping gets confirmed next?
