Oceans may be rare in the inner Solar System—Mars and Mercury are too small for oceans while Mercury and Venus are too hot—but if we consider that water is composed of hydrogen (the most common element in the universe) and oxygen (the third most common element), it seems likely that water would be pretty common too. Indeed, if we look at the worlds out beyond the Solar System’s frost line, we note that there are likely to be oceans within Europa, Enceladus, Ganymede, Ceres, Pluto, and other small worlds.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
