Voyager Treks Into Interstellar Space, An Unexpected Frontier

NASA/JPL-Caltech

This artist's concept depicts NASA's Voyager 1 spacecraft entering interstellar space, or the space between stars. The interstellar plasma is shown with an orange glow similar to the color seen in visible-light images from NASA's Hubble Space Telescope that show stars in the Orion nebula traveling through interstellar space.
