The radiant jets are erupting from a galaxy called 3C 279, located five billion light years from Earth. Even across this immense distance, 3C 279 shines like a cosmic beacon because it is a “blazar,” which means its galactic core is among the brightest and most energetic objects in the universe.
At the center of 3C 279 lies a supermassive black hole that is about one billion times as massive as the Sun. When clumps of matter fall into the hole, they become super-hot and energetic, sparking the enormous jet explosion that scientists see blasting out of the blazar’s pole.

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.
