With and without Adaptive Optics

This 2-panel shows observations of the Galactic Center with and without Adaptive Optics, illustrating the resolution gain. Adaptive optics corrects for the blurring effects of the Earth's atmosphere. Using a bright star, we measure how a wavefont of light is distorted by the atmosphere and quickly adjust the shape of a deformable mirror to remove these distortions. A movie can be viewed on the Animations Page.

Keck Observatory - Twin Telescopes.

Top: The twin telescopes viewed from the Subaru telescope at the top of Maunu Kea, Hawaii.

Bottom: Adaptable mirror(s) of the Keck 2 telescope. Note the man in the bottom of the mirror. The mirrors make minute adjustments to counter atmospherice disturbances.

Resolution in the central 0.5” of the future 30 meter telescope

Still image of animation showing the power of the future 30 m Extremely Large Telescopes. Animation showing the improvement in resolution in the central 0.5” of the Galaxy from seeing-limited to Keck + Adaptive Optics to future Extremely Large Telescopes + Adaptive Optics. Actual orbits are shown in the seeing-limited and Keck cases, while additional simulated orbits are included for the ELT case. A movie can be viewed on the Animations Page.
