The Very Large Telescope Survey Telescope (VST) is equipped with an active optics system in order to correct low-order aberrations. The 2.6m primary mirror is supported both axially and laterally and is surrounded by several safety devices for earthquake protection. We describe the mirror support system and discuss the results of the qualification test campaign.

2019/12/02 · The theorists dubbed the phenomenon "mirror symmetry." Scientists quickly learned that this newfound symmetry could be harnessed to address various mathematical puzzles. In 1991, the physicist Philip Candelas and his colleagues used mirror symmetry to solve a century-old problem, in effect counting the number of spheres that could fit inside a Calabi-Yau space.
