Hubble Space Telescope image of RS Puppis, a Cepheid variable star 6,500 light-years away, surrounded by a dazzling reflection nebula. The star's pulsations create a light echo visible in the nebula, allowing precise distance measurement. This contributes significantly to understanding cosmic distances.

Hubble Space Telescope image of RS Puppis, a Cepheid variable star 6,500 light-years away, surrounded by a dazzling reflection nebula. The star's pulsations create a light echo visible in the nebula, allowing astronomers to precisely measure its distance and luminosity. This contributes to a more accurate cosmic distance scale.
