A supernova steals the show in the Cartwheel Galaxy!

Colourful supernova remnants and their white dwarf stars help shed light on some even more massive and mysterious objects.

Wonderful Chandra observations show that the “Hand of God” supernova remnant MSH 15-52 is slowing down, while studies of SN 2018zd confirm predictions about the existence a third type of supernova.

Space telescope Chandra has obtained stunning images of the centre of our galaxy, with an unexpected discovery of an unusual type of supernova.
