For two recent GRBs (as those in the know call them) even that wasn’t enough. These two emitted individual photons with the highest energies ever seen. One of them zapped out gamma rays with energies of up to a teraelectronvolt — equivalent to about 500 billion times the energy of photons our eyes detect!
This is important, because astronomers had predicted these kinds of energies could be achieved in GRBs, but it had never been seen before. These observations help us understanding what’s going on not just with the GRB itself, but how the expanding material in one interacts with the environment around it.
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.
