Galaxies plowing through the gas and dust permeating vast clusters can leave trails in their wakes made up of material torn away in a process known as ram-pressure stripping. A spiral galaxy known as ESO 137-001 is a well-known example of this spectacular phenomenon, taking on the appearance of a jellyfish trailing long tentacles through space. The Hubble Space Telescope sees hints of the stripped-away material while the Chandra X-ray Observatory reveals an enormous stream of hot gas streaming away into space. Now, the Atacama Large Millimeter/submillimeter Array, or ALMA, radio telescope, working in concert with the European Southern Observatory’s Very Large Telescope, has allowed astronomers to map out cold molecular gas in the trailing clouds.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
