An article under review for publication reports a study on the supernova remnants cataloged as 1E 0102.2-7219 which estimate its place of origin and its age. A team of researchers led by John Banovetz and Danny Milisavljevic of Purdue University in West Lafayette, Indiana, USA, used observations conducted with the Hubble Space Telescope to reconstruct the history of that supernova that occurred in the Small Magellanic Cloud. The conclusion is that the light from the progenitor star’s explosion reached Earth about 1,700 years ago.
