The European Space Authority’s Euclid telescope has reached another milestone. Here’s more from Phys Org:
Euclid’s mission is to measure the shapes of more than a billion galaxies, and the accurate redshifts of tens of millions of galaxies across more than one third of the sky. The redshift is an effect caused by the expansion of the Universe. It stretches the wavelength of light emitted by distant galaxies; the further away the galaxy, the more extreme its redshift. The galaxies in Euclid’s survey will span 10 billion years of cosmic history, and allow scientists to investigate the mysterious dark matter and dark energy that are thought to dominate the Universe.
[Euclid’s] two instruments are now built and fully tested. These have been delivered to Airbus Defence and Space in Toulouse, France, where they are now being integrated with the telescope to form the mission’s payload module.
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.
