    Hi, I heard that the NASA STEREO mission has two spacecraft that can now see the whole sun. Why were we not able to see the whole sun before? What new things will we be able to see? Where can we see the pictures of the other side of the sun?

    You are correct STEREO is a mission that consists of 2 spacecrafts with unique orbits. We combine the images they provide with images from SDO and it provides us a 360 degree view of the Sun. You can read all about it here http://stereo.gsfc.nasa.gov/360blog/

    Hi, Without STEREO, we can only see the side of the Sun facing the Earth at any moment, and also we can only see projections of any three-dimensional solar structure. The goals of STEREO mission are to 'see' the three-dimensional (3D) structure and propagation of Coronal Mass Ejections (CMEs), and other 3D solar coronal structure, such as hot coronal loops over sunspots and solar prominences. We have seen a great many new aspects of the Sun and the heliosphere. If you have any specific questions, I'd be happy to discuss with you. Yan
