Astronomers at the National Radio Astronomy Observatory have used a worldwide network of radio telescopes to find the distance to the Pleiades star cluster, also known as the Seven Sisters. Lots of the stars are very small. They emit very little radiation. That makes it to see those. Also stellar remnants count for astronomers.
