A Moon’s Birth May Have Been Seen for the First Time

Where did the moon come from? How was it made? How long ago? And what did it look like? For the first time, we might have an idea. Here’s more from SlashGear:

“Our work presents a clear detection of a disc in which satellites could be forming,” Myriam Benisty, lead author of the new study and a researcher at the University of Grenoble, France, and at the University of Chile, said of the findings. “Our ALMA observations were obtained at such exquisite resolution that we could clearly identify that the disc is associated with the planet and we are able to constrain its size for the first time.”

The disc has roughly the same diameter as the distance from our Sun to the Earth. It comprises sufficient mass, meanwhile, to make three satellites the size of our own Moon. PDS 70c is adjacent to PDS 70b, another exoplanet first spotted in 2018. Earlier this year, Hubble was able to track PDS 70b as it feasted on gas and dust to build its own mass.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
