Ultra-stable Technology

To view and study Earth-size planets in a star's habitable zone, a telescope must hold incredibly still with almost no movement or temperature change. These animations illustrate the concept of ultra-stable technology and how the Habitable Worlds Observatory will use it to see previously invisible planets.

Complete ultra-stable animation. The animation starts with a distant Earth-like exoplanet. 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.
