Subaru Telescope Improves its Eyesight by a Factor of Ten
On October 9, 2006 the Subaru telescope researchers used a new adaptive optics system to obtain an image of the Trapezium region of the Orion Nebula. A comparison of this new image with a first light image taken when the Subaru telescope first began observing in 1999 (Figure 1), shows a dramatic increase in contrast and detail in the higher-resolution image. With the new system in place, including a newly installed laser guide star system, to measure and correct for the effect of turbulence in real-time, Subaru's eyesight has been improved by a factor of ten, giving astronomers a clearer view of the universe.
