We’ve Now Mapped 1.2M Galaxies Across 650 Cubic Billion Light-Years of Space in Three Dimensions

Absolutely incredible what humans are capable of when we put our minds to work:

The astronomical map you see here doesn’t depict stars, it shows galaxies—1.2 million of them, to be exact, a new record for astronomers. This extraordinary new 3D scan of the universe provides yet more evidence that a mysterious substance known as dark energy is likely causing the universe to expand at an accelerating rate.

The map encompasses 650 cubic billion light-years of space—about a quarter of the sky—and required the work of hundreds of scientists from the Baryon Oscillation Spectroscopic Survey (BOSS). BOSS is a program within the Sloan Digital Sky Survey III (SDSS-III) that measures the sound waves of the early universe, which left faint imprints on the cosmic background radiation—the “afterglow,” as it were, of the Big Bang. They also left their imprints on the distribution of galaxies, which is what BOSS is using to map the positions and distances of galaxies back through time.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
