Cool piece on the science of locating the smallest stars in our universe, from The Atlantic.
For astronomer Alexander von Boetticher, false positives in data are actually a good thing.
That’s how von Boetticher and his colleagues at the University of Cambridge discovered the smallest star ever measured. The star showed up in data from a British-led mission known as the Wide Angle Search for Planets, or WASP. WASP looks for potential exoplanets by looking for dimming in the brightness of stars, a signal that an object is passing in front and blocking the light. The mission has detected dozens of planets this way. Sometimes, the source of the dimming turns out to be something else entirely. “Every now and then, instead of finding an exoplanet orbiting some star, it actually finds a very small star that’s orbiting a star,” von Boetticher said.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
