Breakthrough Listen—the astronomical program searching for signs of intelligent life in the Universe—has submitted two publications to leading astrophysics journals, describing the analysis of its first three years of radio observations and the availability of a petabyte of radio and optical telescope data. This represents the largest release of SETI data in the history of its field.
Listen is performing detailed observations of a sample of 1702 nearby stars (within about 160 light years from Earth) using the Green Bank Radio Telescope (GBT) in West Virginia and CSIRO’s Parkes Radio Telescope in Australia. In addition, exploration of a wide swath of our Galaxy’s disk is underway at Parkes, observations of a one-million-star sample will soon commence at the MeerKAT telescope in South Africa, Lick Observatory’s Automated Planet Finder is being used to search for optical signals, and collaborations continue to grow with a number of partner facilities across the globe.

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.
