Artist’s illustration of supernova 1987A

This artist’s illustration of supernova 1987A reveals the cold, inner regions of the exploded star’s remnants (in red) where tremendous amounts of dust were detected and imaged by ALMA. This inner region is contrasted with the outer shell (lacy white and blue circles), where the energy from the supernova is colliding with the envelope of gas ejected from the star prior to its powerful detonation.
