You are an alien astronomer living 4.5 billion years from now. The Sun that the Earth orbits has died and become a white dwarf. What would you see if you looked at humanity’s former Solar System?
Based on the first discovery of a giant planet orbiting a white dwarf, reported in two new papers in the journals Nature and Astrophysical Journal Letters, researchers now believe that this hypothetical alien would be able to observe signatures of our Solar System’s largest planets—Jupiter, Saturn, Uranus, and Neptune—just by looking at the dead Sun.

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.
