I got to create the #dataviz / data art for the article on "25 years since Dark Energy's discovery" in the December issue of @sciam ✨ Using ±1.6 million dots to represent objects (almost all entire galaxies!) from the DESI Early Data Release.

Ya'll, I made a planetarium movie!! It's about mapping the universe with @desisurvey and includes a flight through the real positions of 14 million galaxies. For anyone without access to a planetarium, here's a flat version. #5000Eyes 1/3
