An Astronomically Wrong Assumption

For decades, astronomers had assumed that the amount of light we observe from a galaxy could be used to work out how much star material it contains. From this, they could work out how many stars are in the galaxy. However, when a team of astronomers recently put this theory to the test, they found that a galaxy’s brightness isn’t a good way of counting its stars.
