Movie: Approaching Light Speed 
Image Credit & Copyright: Antony Searle & Craig Savage (ANU)

Explanation: What would it look like to travel near the speed of light? Strange visual effects would appear as documented in the above relativistically-accurate animation. First of all, relativistic aberration would cause objects to appear to bunch up in front you. Next, the Doppler shift would cause the colors of forward objects to shift toward the blue, while things behind you would shift toward the red. Similarly, the world in front of you would seem to move unusuallyfast, while the world behind you would appear to slow down. Objects to the sides will appear rotated, possibly enabling surfaces normally hidden from you to become visible. Of course, since constant motion is relative, the same effects would occur were you to remain stationary and the entire world advanced toward you.

I see a giant rock floating in space with a giant mountain on its side - now.

After traveling nearly four years and almost two billion miles, NASA's Dawn satellite this summer began orbiting the massive asteroid Vesta. Vesta's straight-line distance from Earth varies depending on the time of year, but when these pictures were taken, Vesta is about 117 million miles. Dawn launched in 2007 and is expected end its mission in 2015 after moving on to study the dwarf planet Ceres.

And just to put things in perspective, a mountain on Vesta is 12.3 miles high, taller than anything on Earth. To compare, Mauna Kea in Hawaii is less than 5 miles tall.
