EARTHSIGN
Light Echo This sequence of pictures was captured by the Hubble to demonstrate the echoing of light through space and reflecting off surrounding shells of dust to reveal a bull’s-eye. This shows the changes in the stellar dust as different parts are illuminated in an effect called ‘light echo.’ From the sequential images, the nebula appears to expand from 4 to 7 light-years and creates an illusion that the dust is expanding into space faster than the speed of light.
