A strange ‘chirp’ in a brilliant stellar blast points to a #magnetar
About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical #supernova, putting it in a rare group of superluminous #supernovas. Now, #astronomers believe they know what made the explosion so bright — an extreme type of star called a magnetar.
