The elements that make up nearly all that you are and everything you can see first came from the explosion of a massive star.
Stars can end their lives in an explosion—a supernova—collapsing on themselves and ejecting material out into the universe.
Through telescopic data, you're looking at the remnants of one star in the Milky Way, Cassiopeia A.
When you look up at the stars at night, you see what's on the visible spectrum, but there's so much more. The visualization is based on real data from multiple telescopes, including @nasachandraxray, that measure invisible rays across the electromagnetic spectrum.
Color is the main tool used to translate data to images that tell a story of what is going on in space. Here each represents different elements, like iron radiation, argon and neon.
Step into the explosion of a massive star with a new 360-degree video and interactive simulation at s.si.edu/supernova (link in bio). "Journey through an Exploded Star" was produced by the Smithsonian Center for Learning and Digital Access in conjunction with the Center for Astrophysics | Harvard and Smithsonian.
