Sean Goebel is an astronomy graduate from the University of Hawaii. This gives him access to one of the best scientific observatories in the world. Soaring 14,000 feet above sea level Mauna Kea Observatories in Hawaii offer some of the best conditions for astronomy research in the Northern Hemisphere. Not only is Sean a scientist he’s also a photo enthusiast. Over the course of several nights in April, he made this gorgeous time-lapse of the telescopes firing off lasers into a star filled sky.
Why were they shooting off lasers? Sean says, “Actually, the lasers are real. They’re used for adaptive optics. Just as waves of heat coming off pavement blur out the detail in faraway objects, winds in the atmosphere blur out fine detail in the stars/galaxies/whatever is being observed. This is the reason that stars twinkle. The laser is used to track this atmospheric turbulence, and one of the mirrors in the telescope bends hundreds of times per second in order to cancel out the blurring. Adaptive optics is pretty cool, and was the topic of my first 8-month research project in graduate school.”

We see the marvels of science around us just exploding with new technology almost on a daily basis. It becomes so much we almost become desensitized to the rapid changes going on. Kodak invented the first digital camera back in the mid 70’s and it was a .01 or .001(don’t quite remember) megapixel black and white camera. Look where we are now and every year the camera just gets a little smarter. Even though they have been using lasers and synching telescopes together for some time, I wonder how far into the past we are going to be able to see someday. I’ve always felt the good and pure of our planet will someday overcome most of our weaknesses and I gotta say it sure is a fun ride here on good old planet Earth.
