An article published in the journal “Nature Astronomy” describes the study of the supernova remnants identified as 1E 0102.2-7219 in the Small Magellanic Cloud. A team of researchers led by Frédéric Vogt used the MUSE instrument installed on ESO’s VLT to observe a large ring of gas in that system that is slowly expanding into the depths of several other gas filaments that are quickly moving away, leaving behind a neutron star in the center.
