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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
