This image from NASA's Chandra X-ray Observatory displays the locations of various elements in the Cassiopeia A supernova remnant. Silicon is shown in red, sulfur in yellow, calcium in green, and iron in purple. Each element emits X-rays within specific energy ranges, enabling the creation of maps that indicate their locations. The blue outer ring represents the blast wave from the explosion. Astronomers study supernova remnants to gain insights into how stars create and distribute many of the elements found on Earth and throughout the universe.
