The second interstellar object on record has visited our solar system, according to astronomical observations made in recent week. But how does this new visitor differ from ‘Oumuamua, the first interstellar object?
Scientists have been eager to learn more about Comet C/2019 Q4 (Borisov) since amateur astronomer Gennady Borisov first spotted it on August 30. Follow-up observations determined found that its orbit suggests it originated from outside the solar system. A comparison to the first interstellar object, ‘Oumuamua, could provide an interesting perspective on what these objects are like generally.
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.
