The European Southern Observatory (ESO) was founded 55 years ago this week. It has some of the world's most powerful ground-based telescopes. In the picture, besides the amazing southern sky seen from a clear dark site, you can see one of the laser guide stars. These are used for what is called "adaptive optics". It allows the telescopes to stabilize the image which may be blurred by the atmosphere.
