Explanation: Why are these people shooting a powerful laser into the center of our Galaxy? Fortunately, this is not meant to be the first step in a Galactic war. Rather, astronomers at the Very Large Telescope (VLT) site in Chile are trying to measure the distortions of Earth's ever changing atmosphere. Constant imaging of high-altitude atoms excited by the laser –– which appear like an artificial star –– allow astronomers to instantly measure atmospheric blurring. This information is fed back to a VLT telescope mirror which is then slightly deformed to minimize this blurring. In this case, a VLT was observing our Galaxy's center, and so Earth's atmospheric blurring in that direction was needed. As for inter-galaxy warfare, when viewed from our Galaxy's center, no casualties are expected. In fact, the light from this powerful laser would combine with light from our Sun to together appear only as bright as a faint and distant star.

Suddenly, my brand new 1 Watt blue laser seems woefully inadequate.

Look at that sky. Its beautiful.

I sense a great disturbance in the force.......

This is how it starts. Some pilot scooting along on his way to Vega or HIP 601293 gets blinded by the laser and gets miffed. Spfffffft.... no more earth. Thanks Dumbass!

Yes.


So far, the best night sky I can every remember seeing was in Minnesota, just a few weeks ago. It's supposed to be even better during the winter.

Down here in Florida, due to ocean haze, even on a very clear night, the milky way is all but completely invisible, though it's dominant in clear skies.


I really wish we could see more of the night sky with our naked eyes.

it's like the becon we have continiously been broadcasting........some galatic giant will come up to our planet holding his ears and step on us...and shake their head and just walk away.....
