Keck Adaptive Optics
Mosaic of 24 images (total integration time: 120 seconds), this image
shows the very central area of our own galaxy, the Milky Way. It was
obtained on May 26th, 1999. The central arcsecond (inset) will help
to determine the mass of the central back hole Sgr A*.
Also, you can view an animation of the effect of turning the loop "ON"
when pointed at the galactic center through this mpeg movie (180 ko) or this animated gif (1.5 Mo) page.
