Researchers Build “Supernova in a Box” to Study the Physics of Stellar Blasts #SpaceSaturday
Scientists at the Georgia Institute of Technology have created a way to model at small scales the exploding stars that can lead to nebulae. Here’s more from Astronomy Now:
The device is about the size and thickness of a door but shaped like a slice of pizza, about four feet wide at the top and standing on its tip. When a small explosion is triggered in the tip, the blast wave moves toward the top through two layers of gas that are illuminated by laser beams.
“We suddenly go from a perfectly still chamber to a little supernova,” said principal investigator Devesh Ranjan, a professor in Georgia Tech’s George W. Woodruff School of Mechanical Engineering. “There was a lot of engineering done to contain the blast and at the same time make it realistic where it hits the gas interface in the visualisation window.”

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.
