A laser attacks the Galactic Center
Why are these people firing a powerful laser to the center of our galaxy?
Fortunately, this does not mean it is the first step in Star Wars.
Rather, astronomers at the Very Large Telescope located in Chile are trying to measure distortions of the ever-changing Earth's atmosphere .
constant photographing of atoms excited by the laser at high altitude, which appear as a artificial star, allowing astronomers to measure the atmospheric distortion instantly.
This information is sent back to the VLT telescope mirror, then, is slightly deformed to minimize this distortion.
In this case, one of the VLT was watching our galactic center, so you need to measure the distortion of Earth's atmosphere in that direction.

I stop at the point made concerning the distortion of the atmosphere, in order to make the parallelism of the existing images of galaxies behind the clusters of galaxies where the gases in the environment created by these and other distortions of galaxies more distant and have wrongly assumed that generated the bending of light by gravitational attraction, as in this case the straight beam of light distortion effect looks like a star.
