4/10 The "echo" happens when this expanding light hits surrounding gas and dust. Imagine a shell of gas one light-year around a supernova. We first see the nearest point illuminate, then progressively more distant parts.

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.

Two images of V838 Monocerotis, a variable star, taken in May and September 2002 by the South African Astronomical Observatory. The images show the star's dramatic transformation and the expansion of its surrounding light echo nebula. The nebula is a result of light reflecting off shells of material ejected by the star, offering a glimpse into its history. The star's behavior defies conventional understanding of stellar life cycles.
