View Full Version : Keck Uses Adaptive Optics for the First Time

SUMMARY: The 10-metre Keck II observatory took an important step forward recently when it began observations with its new adaptive optics system. The system uses a laser to create a fake star about 90 kilometres up in the sky - a computer can then use this to calculate how to remove the effect of atmospheric disturbances. Adaptive optics have been used on smaller telescopes, but this is the first time it's been employed on a telescope as large as the mighty Keck II; it took nine years to adapt the observatory.
