Until now, all the pictures of the sun have been straight-on head shots. Soon, scientists will be getting a profile.
NASA and the European Space Agency are set to launch a joint mission on Sunday to provide the first-ever look at the sun's poles. Previous images have all been taken from approximately the same angle, roughly in line with the star's equator.
Scientists are hesitant to guess what the elusive poles of the star might look like. "I hate to speculate," says Holly Gilbert, the NASA project scientist for the mission.
