Why Nebulae Fool Astronomers ⚡ экспресс
Original: "There is no single density: star-forming regions and galaxies hold more dense ionized gas than long assumed"
When measuring gas density in nebulae using different methods, astronomers get different numbers — this isn't a mistake, but a key to understanding stellar nurseries.

Take a look at a nebula photo—it's not just a fluffy cloud, but a mixture of diffuse gas and dense clumps. Every instrument measures density in its own way, and that's not a mistake, but a clue to understanding stellar nurseries. Density there isn't a single number, but a whole spectrum of values.
🎯 Even the most rarefied part of a nebula contains hundreds of times more atoms than the best vacuum we can create in Earthly labs.
