Now, though, thanks to NASA's STEREO program (a loose acronym for Solar Terrestrial Relations Observatory), we can see the entire sun in full, stunning 3D. The space org launched two satellite camera's back in 2006 and sent them rotating in opposite directions around the sun. Just yesterday, they reached a point where they are filming our star from exact opposite directions -- providing a complete view. We will now have the sun covered for the next 8 years. Watch the video above.
