SPACE: Soar Through the Heart of a Supernova

Credit: Smithsonian Institution

When the universe’s largest stars run out of fuel and die, they explode in technicolor tsunamis of gas and dust that can stretch on into space for dozens of light-years. To see the full array of cosmic colors left behind by a star gone supernova, you generally need some pretty sophisticated telescopes capable of seeing light beyond the visible spectrum. But today, you can grab a front-row seat to those cosmic pyrotechnics by clicking over to this new 3D simulation released by the Smithsonian.

The interactive, 360-degree graphic allows armchair astronauts to navigate through the heart of a supernova remnant using just their mouse and arrow keys. The simulation shows the likeness of an actual supernova site called Cassiopeia A, a 10-light-year-wide cloud of stellar debris located in the Milky Way’s Cassiopeia constellation (about 11,000 light-years from Earth). The supernova’s colorful likeness was re-created using actual observations measured in gamma ray, infrared, ultraviolet, X-ray and radio wavelengths, provided by half a dozen observatories around the United States.

With all these elusive light sources laid on top of one another, the resulting image is a rainbow collage of green iron, yellow silicon, red argon and magenta neon gas clouds crisscrossed by purple jets of scorching-hot matter streaking out of the debris. At the center of this gassy mosaic is the ominous image of a neutron star — the ultradense, ultrasmall core of the collapsed giant star responsible for the supernova debris in the first place.
