By capturing detailed, long-exposure images of space features like pulsing, Cepheid variable stars, Hubble confirmed the true nature of the Andromeda Nebula and others.

She was particularly interested in Cepheid variables, which are stars whose brightness pulses regularly, so they get brighter and dimmer with a particular period.
