A breakthrough was made a few years ago when some were found to repeat, meaning follow-up observations could be made. That was also a big clue to their origin; something that explodes catastrophically and destroys itself can’t repeat, so it’s not some weird kind of supernova. Another important finding was one that was traced to a spiral galaxy 500 million light years away. Getting a distance is crucial, because that can tell you the total energy emitted by the event. That narrows down suspects. Even better, that one was a repeater with a 16-day cycle to its bursts.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
