This illustration shows the location of Cepheid variables found in the spiral galaxy NGC 5584. Ultraviolet, visible, and infrared data taken with Hubble's Wide Field Camera 3 in 2010 reveal Cepheids of varying periods. Those stars with periods of less than 30 days and between 30 and 60 days are marked with green and blue circles, respectively. A small number of Cepheids, with periods larger than 60 days, are marked in red.

| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: White: F350LP (Long Pass) Blue: F555W (V) Orange: F814W (I) |
