The Unique Moon-Sun Proportions that Allows the Viewing of the Sun’s Corona During a #SolarEclipse
This retro video from PBS Learning puts a whole number (that I was previously unaware of) on the proportions between the sun and moon, and the distance between earth and both of those heavenly bodies, that allows for the upcoming solar eclipse to happen in the first place. Watch the video below and add this to your eclipse trivia memory bank!
Every now and then, the Sun, Earth, and Moon align so that, when viewed from the Earth, the Moon eclipses the Sun’s light. Solar eclipses are fairly common — the Moon will block out some portion of the Sun at least twice a year. However, it is still a special event to be able to witness a total solar eclipse. In this video segment adapted from NASA, learn how solar eclipses happen and why they are so difficult to witness.
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.
