Summary
| Description | In the same way that two eyes give humans a three-dimensional perception of the world around us, the twin spacecraft of NASA’s Solar Terrestrial Relations Observatory mission, or STEREO, enable us to understand the sun in 3-D. Thanks to this mission, which launched on Oct. 25, 2006, we can see and study the sun from multiple viewpoints – crucial for understanding solar activity and the evolution of space weather. One of STEREO’s key instruments is called a coronagraph, which is used to study the corona, the sun’s outer atmosphere. Each of STEREO’s coronagraphs has a metal disk called an occulting disk. The occulting disk blocks the sun’s bright light and makes it possible to discern the detailed features of the surrounding corona, which is about one million times dimmer than the sun. Much like the way the bright headlights of a semi-truck at night hide just how big the truck is, the brightly shining sun makes it difficult to study the much fainter corona.
