Good morning, Rallypoint, and welcome to the June 26th edition of Astronomy Picture of the Day (APOD): "Light Echoes from V838 Mon." We've all heard sounds echo (i.e. thunder, frieght train whistle, voice, etc). This is due to the wave properties of sound. Light also behaves like a wave...so it too can 'echo.' But given the speed of light (~300,000,000 km/sec), the surfaces to create a light echo need to be far away.
There is an animated GIF on the Wikipedia page for V838 showing the progression of the light echo as captured by the Hubble Space Telescope. Feel free to search it up for yourself; I'll post a link to that page in a separate comment.
