Earlier this year, Lawrence Livermore engineering technical associate Pam Danforth applied 30 years of laser experience to an out-of-this-world problem — bringing new life to the University of California’s Lick Observatory Laser Guide Star.
The Lick Observatory’s Laser Guide Star is vital to astronomers because a natural guide star isn’t always near an object they want to observe. By training the guide star beam into the sky near such an object, an artificial guide star of glowing atmospheric sodium ions is created, allowing the laser guide star to function like a natural guide star and provide correct focus for the object they want to observe.
“I have always been enthusiastic about helping astronomers see further and more clearly into space. I enjoyed being part of this developmental effort for many years,” Danforth said. “To be able to make a dramatic impact on the world of astronomy was very exciting.”
It was this combined expertise that made Danforth the right person to help bring the Laser Guide Star back to peak operating condition. According to Lick Observatory Superintendent Kostas Chloros, this work was needed as the system’s performance and efficiency had degraded, impacting the research programs that require the use of a laser guide star.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
