There might be a ninth planet. It turns out it’s not just the ancient alien folks who are looking for an orbit of the fabled planet. Here’s more from Astronomy Now:
For the past several years, astronomers have been searching for an unseen planet beyond the orbit of Pluto, a presumed world with 10 times the mass of Earth that could be responsible for the seemingly clustered orbits of small Trans-Neptunian Objects, or TNOs, in the extreme outer solar system. So far, “Planet 9” has eluded detection.
Dealing a possible blow to the theorised planet, a team of researchers led by Kevin Napier of the University of Michigan suggests selection bias may have played a role in the original justification for Planet 9.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
