According to astronomers how many galaxies are distributed across the observable universe

Astronomers estimate that there are approximately 100 to 200 billion galaxies in the observable universe. This number has evolved over time with advancements in technology and observational techniques, and some estimates suggest that there could be as many as 2 trillion galaxies when considering smaller, fainter galaxies that were previously difficult to detect. The vast majority of these galaxies are too faint to be observed directly with current telescopes.
