Its story

Toward the starry heart of Sagittarius, where the plane of the galaxy turns dense and golden, beats this blue B-type star with mild variability. Its light set out 557 years ago, around 1467, when Gutenberg was already transforming Europe with movable-type printing. Far hotter and more massive than the Sun, its glow ripples with restraint, a reminder that even the steadiest suns hide inner tides of plasma.
