Life on Earth is at least 3.5 billion years old, judging by the earliest known fossils of microorganisms. But how living creatures emerged on our home world, the only place in the universe where we know life exists, is one of the most tantalizing unsolved mysteries in science.
A mountain on the Moon could shed light on this important question, according to a forthcoming study in the journal JGR Planets. A robotic or human mission to the 250-meter-high peak, located in an ancient impact basin called Mare Crisium, would help scientists reconstruct key details about Earth’s first billion years, including the advent of Earthlings, the authors said.

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.
