A white dwarf is what’s left over after a star like the Sun dies. Right now the Sun is happily fusing hydrogen into helium in its core, providing it with the energy we receive as well as the pressure it needs to support the octillion or so tons of material in its outer layers pressing down on the core.
When that hydrogen fuel runs out, a complicated series of events occur. Some steps along the way are that the now all-helium core starts to fuse to become carbon and oxygen, while the outer layers swell up and start to blow away in a dense winds of particles. Eventually the core becomes exposed to space. Hot and super-dense, we call this object a white dwarf. Once formed, it generally just kinda sits there in space, slowly cooling off with time.
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.
