In November 2023 our Integral telescope spotted a sudden explosion from a rare object. For only a tenth of a second, a short burst of energetic gamma-rays appeared from the direction of the bright galaxy M82.
Only a few hours later, our XMM-Newton telescope searched for an afterglow from the explosion but found none. Astronomers realised that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
