NASA’s Spitzer Space Telescope will cease operations in January 2020, but the infrared observatory is still capturing stunning views of the cosmos like this large mosaic showing multiple star clusters made up of suns spanning the full range of stellar evolution, from infancy to old age. The mosaic (click on the image above for a labled view) thus provides a family portrait of sorts, featuring young gas-and-dust-rich star forming regions — Cepheus C, for example — to more mature clusters — Cepheus B — containing middle-age suns and stellar senior citizens. The Spitzer mosaic also shows off a variety of other interesting targets, including V374 Ceph, a massive star that appears to be surrounded by an edge-on disc of debris, and a runway star plowing through gas and dust and creating a visible shock wave. The video below from NASA’s Jet Propulsion Laboratory provides a guided tout.

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.
