      Hi aarom. Not an astrophysicist, but my guess is that every galaxy is different! My understanding is that there are several hundred billion (that’s more than 100,000,000,000), but this is largely a guess, and the numbers that scientists estimate varies pretty widely. Charlie might have a better answer?
