NASA’s Solar Dynamics Observatory captures this video of a filament eruption on the sun last Friday at 4:36 in the afternoon EDT. The segment of the video in 304 angstroms wavelength, during which the sun appears red, covers a period of time lasting three hours.
The explosion sent a wave of solar plasma, known as a coronal mass ejection, toward the Earth at a speed of 900 miles per second, resulting in a beautiful aurora over parts of the Northern Hemisphere last night.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
