Interstellar space is not empty but filled with gas, dust and energetic particles. We explore this cosmic medium in more detail here.

The universe is different. “In the interstellar medium,” says Schilke, “argon-36 is by far the most abundant, and we were just too stupid to realize it.” ...

The Milky Way's interstellar medium—that is, the dust and gas that threads between our galaxy's billions of stars—is an abundant yet elusive material.
