Dynamic Earth-A New Beginning

The visualization 'Excerpt from "Dynamic Earth"' has been one of the most popular visualizations that the Scientific Visualization Studio has ever created. It's often used in presentations and Hyperwall shows to illustrate the connections between the Earth and the Sun, as well as the power of computer simulation in understanding those connections.

There is one part of this visualization, however, that has always seemed a little clumsy to us. The opening shot is a pullback from the limb of the sun, where the sun is represented by a movie of 304 Angstrom images from the Solar Dynamics Observatory (SDO). It is difficult to pull back from the limb of a flat sun image and make the sun look spherical, and the problem was made more difficult because the original sun images were in a spherical dome show format. As a result, the pullback from the sun showed some odd reprojection artifacts.

The best solution to this issue was to replace the existing pullout with a new one, one which pulled directly out from the center of the solar disk. For the new beginning, we chose a series of SDO images in the 171 Angstrom channel that show a visible coronal mass ejection (CME) in the lower right corner of the solar disk. Although this is not the specific CME that is seen affecting Venus and Earth later in this visualization, its presence links the SDO animation thematically to the later solar storm. The SDO images were also brightened considerably and tinted yellow to match the common perception of the Sun as a bright yellow object (even though it is actually white).
