Why are stars there?

When enough hydrogen gas collects in a region of space, the collective gravity of the gas begins to pull all the hydrogen atoms together. Eventually, when enough hydrogen has fallen together, it heats up and compresses the gas. If there's enough gas, it will collapse under gravity until the internal temperature and pressure are very high, and hydrogen fusion begins.

And a star is born.

It's not all that unusual; there are perhaps a trillion stars in the Milky Way, and hundreds of billions of other galaxies in the universe.
