Diffuse Background Cool Fact


Superbubbles are produced as large hot stars interact with the surrounding interstellar medium. When stellar winds combine with supernova explosions in a relatively small region of space, a superbubble is produced. Inside is a large cavity filled with very tenuous hot gas. If the gas inside is hot enough, it emits X-rays.
