The camera pulls back until the planet is hidden by the overall glare of the star.  Quickly pulling farther back, the starlight reaches the Habitable Worlds Observatory.  The animation transitions to a representative internal view.  The starlight bounces from the main mirror to the secondary and into the coronagraph system.  If the mirror sections are too unstable, the coronagraph can't remove all the light directly from the star.  With ultra-stable technology, the mirror sections are much more still and two planets appear.",
