In the Milky Way, the most abundant gas is hydrogen, accounting for about 75% of the galaxy's baryonic (normal) matter. This hydrogen exists primarily in atomic form, as well as in molecular clouds where it can form stars. Helium is the second most abundant gas, making up about 24% of the galaxy's mass. Together, these two elements dominate the composition of the interstellar medium in the Milky Way.

How was the Milky Way created?

The Milky Way formed about 13.6 billion years ago from a huge cloud of gas and dust in space. As gravity pulled these materials together, they began to collapse and eventually formed the Milky Way galaxy that we see today. The Milky Way continues to evolve through the interactions of stars, gas, and dark matter within it.


Are there gas clouds in the Milky Way?
