The haze particles are formed when ultraviolet light from the Sun and/or subatomic particles zipping around space slam into the nitrogen and methane, breaking it down into elements that then rearrange themselves into more complex molecules. Some of them are simple rings of carbon, and some are far more complex molecules called PAHs — polycyclic aromatic hydrocarbons. It’s not been clear how the simple ones link up to form the bigger ones, but now, for the first time, this process has been simulated in a lab and the results examined using a powerful type of microscope that reveals the basic atomic configurations of the molecules.
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.
