Zoom on NGC 4993
This movie zooms from a ground-based view on towards the lenticular galaxy NGC 4993 in the constellation Hydra. Within this galaxy, a neutron star collision generated gravitational waves and an associated gamma-ray burst. It also resulted in an explosion called a kilonova that was visible to telescopes including the NASA/ESA Hubble Space Telescope.
The zoom ends with a loop of the three Hubble observations made in the first days after the explosion, clearly showing the evolution of the colour and brightness of the kilonovoa.Credit:
