Williamina Fleming

Williamina Paton Stevens Fleming was a Scottish-American astronomer who lived from 1857-1911. She discovered 10 of the 24 novae then known. Novae are stars that suddenly increase their brightness then fade to their former dimness over a period of months or years. She also discovered over 200 variable stars. Variable stars are those that change in light intensity over time. Fleming worked at the Harvard Observatory for many years.
