A time-lapse created by U of T astronomer Yvette Cendes shows the shockwave of Supernova 1987A expanding
outward over thirty years and slamming into debris that ringed the original star before its demise

The supernova was the cataclysmic death of a blue supergiant star, some 168,000 light-years from Earth, in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way Galaxy. It was the brightest supernova to appear in our skies since Kepler's Supernova in 1604 and the first since the invention of the telescope.
The brilliant new star was first spotted by two astronomers working at the Las Campanas Observatory in northern Chile the night of the 24th: the University of Toronto's Ian Shelton, and a telescope operator at the observatory, Oscar Duhalde.
Now, Yvette Cendes, a graduate student with the University of Toronto and the Leiden Observatory, has created a time-lapse showing the aftermath of the supernova over a 25-year period, from 1992 to 2017. The images show the shockwave expanding outward and slamming into debris that ringed the original star before its demise.
In an accompanying paper, published in the
Astrophysical Journal, Cendes and her colleagues add to the evidence that the expanding remnant is shaped--not like a ring like those of Saturn's--but like a donut, a form known as a torus.
They also confirm that the shockwave has now picked up some one thousand kilometres per second in speed. The acceleration has occurred because the expanding torus has punched through the ring of debris.
