See it on NASA's siteWhat would it look like to travel near the speed of light? This animation shows the strange visual effects that would appear. Relativistic aberration would cause objects to appear to bunch up in front of you. The Doppler shift would cause forward objects to shift toward blue, while things behind you would shift toward red. The world in front of you would seem to move unusually fast, while the world behind you would appear to slow down.
