Cepheid Variable Stars Period Luminosity Diagram Earthsky And it turns out what she was looking at were a class of stars called cepheid or cepheid, cepheid variable stars. and what's interesting about them is two things. Cepheid variable stars and distance measurement in space space engine black holes | stars, black holes and galaxies | cosmology & astronomy | khan academy.
Cepheid Variables Light Curves Starlight Space Fm Our universe is defined by stars. this topic explores how they came to be and where they end up. this includes a discussion of black holes and galaxies. In this section of khan academy, you'll learn about the brain bending vastness of time and space. we go from plate tectonics here on earth to entire galaxies and beyond.

If you want to discover a new cepheid star, you take an image of a portion of the night sky over many nights. you then write down the brightness (magnitude) of each star from every night’s image and see if any of these magnitudes are changing from night to night.
