Researchers used one of the world’s most powerful supercomputers to better understand how jets of high energy plasma escapes the intense gravity of a black hole, which swallows everything else in its path—including light.
Before stars and other matter cross a black hole’s point of no return—a boundary known as the “event horizon”—and get consumed by the black hole, they get swept up in the black hole’s rotation. A question that has vexed physicists for decades was how some energy managed to escape the process and get channeled into streams of plasma that travel through space near the speed of light.
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.
