Scientists Discover ‘Regular Patterns’ in Group of Mysterious Pulsing Stars
MOTHERBOARD shares a University of Sydney study about the possible evolution of the Milky Way.
But while some pulsating stars beat at regular intervals, others are a little jazzier. For instance, astronomers have puzzled for years by the seemingly discordant oscillations of so-called delta Scuti stars, which are about 1.5 to 2.5 times the mass of the Sun. The light from these stars reveals oscillations that are so complex that scientists have been unable to decode them into regular patterns, known as “pulsation modes”—until now.

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.
