For the first time ever, scientists have glimpsed the exposed core of a giant planet, providing a rare opportunity to peer at the heart of an alien world.
The planet, called TOI-849b, is slightly smaller in size than Neptune, but up to three times more massive, making it “the densest Neptune-sized planet discovered so far,” according to a study published on Wednesday in Nature. The planet was originally discovered in 2018 by NASA’s Transiting Exoplanet Survey Satellite (TESS), but it wasn’t until last year that scientists began to grasp its bizarre properties, which have never been observed in any star system before.
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.
