Changing colour time-lapse from VISTA

This time-lapse video shows a series of images from the VISTA infrared survey telescope at ESO's Paranal Observatory showing the galaxy NGC 4993 in August 2017. The explosion of a kilonova in this galaxy was accompanied by the emission of both gravitational waves and gamma rays. The object was initially blue but then became much redder before fading.
