Why we still don't know how many stars are in the Milky Way
Briefly

Determining the number of stars in the Milky Way galaxy remains a significant challenge, with estimates varying widely from 100 billion to 400 billion. Our understanding of the galaxy is hampered by dust obscuring the galactic plane, complicating our ability to discern its spiral arms and other structures. Despite substantial knowledge about the wider Universe, the Milky Way presents unique hurdles that reflect the complexities of astronomical observation and the scientific process, highlighting our ongoing quest for accurate cosmic information.
While we live within the Milky Way, understanding its structure and the exact number of stars remains a challenge, with estimates ranging from 100 billion to 400 billion.
Learned guesswork is often required when studying the Milky Way, particularly due to the extensive dust that obscures its galactic plane, complicating our understanding.
