Some of the largest single structures in the galaxy are huge dark nebulae, clouds of gas and dust that are extremely cold in human terms and emit almost no visible light. These are called Giant Molecular Clouds — they’re cold enough that atoms can stick together to form more complex molecules — and are so utterly dark that we tend to see them in silhouette against the star-filled Milky Way.
… to our eyes, that is. We see only a narrow band of the entire electromagnetic spectrum. But others parts exist, like radio waves, X-rays, ultraviolet. We’ve built telescopes and equipped them with detectors to see these other kinds of light; many are in space because we need them to be above our atmosphere, which absorbs those kinds of light, making it opaque to them.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
