What is now the atmosphere of Mercury was created by the ghosts of that magma ocean. Even the atmosphere lost mass from all those particles flying everywhere, though not much. As researcher Noah Jäggi of the University of Bern found, it was really through vaporization of the magma ocean that the scorched planet lost most of its mass. There wasn’t really that much stuff that fled the atmosphere. Jäggi recently led a study published in The Planetary Science Journal.
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.
