Key Points
The James Webb Space Telescope has captured details of the Cassiopeia A, the remnant of one such explosion...
But the new mid-infrared images captured by Webb hold a wealth of new scientific information that scientists are only beginning to tease out...
These heavy elements are what cosmic dust is made of, and it is, therefore, difficult to explain the origins of the dust without attributing some of it to supernovae...
But there is a problem. Based on current observations of supernovae, it is not possible to explain the sheer amount of dust astronomers see in those early galaxies..
Elements like Calcium, which we find in our bones, and iron, which is in our blood, are spread across interstellar space by supernovae, providing the seeds for new stars and planets..
