First light images from the 4-metre Daniel K. Inouye Solar Telescope atop Mount Haleakala in Hawai’i, the most powerful in the world, provide a mesmerising glimpse of our star’s churning surface, capturing details as small as 30 kilometres (18 miles) across in boiling cell-like structures about the size of Texas.
In a process known as convection, hot plasma boils to the surface in the bright centres of the cells, cools and then sinks back down in dark lanes. In those lanes, astronomers can discern small, bright markers of magnetic fields thought to channel energy up into the Sun’s super-heated corona.
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.
