People die, stars die, and yes, even galaxies die. But while scientists have observed many “dead galaxies” that do not produce new stars, the actual transition from an active star-forming galaxy to a galactic corpse is not well understood.
The missing link in this mystery could be “cold quasars,” a new type of system discovered by Allison Kirkpatrick, assistant professor of physics and astronomy at the University of Kansas. Kirkpatrick announced her findings in a livestream presentation at the American Astronomical Society meeting in St. Louis on Wednesday.
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.
