"Scientists said yesterday (February 22, 2021) that they’ve now created a 3D plot of more than a million pairs of binary stars, that is, double stars orbiting a common center of gravity. Astronomer Kareem El-Badry of UC Berkeley created the new plot, which wildly improves upon previous data that revealed just 200 double-star pairs."
