Astronomers used the Chandra X-ray Observatory telescope to look at Cassiopeia A, a remnant located in the Cassiopeia constellation. Each element produces a unique x-ray signature, allowing them to be identified and mapped. Cassiopeia A has dispersed masses of sulfur equal to 10,000 Earths, 20,000 Earth masses of silicon, and about 70,000 Earth masses of iron. Many experts think the star exploded around the year 1680 and was once 16 times the mass of our sun.
