Its story

At the heart of Virgo pulses a red M-type giant, far cooler than the Sun and with restless light — its brightness shifts to a slow, private rhythm. When this light set out, some 461 years ago, Gutenberg's press had been transforming the world for barely a century and Copernicus was publishing his heliocentric revolution. That crimson pulse crosses Virgo like an ancient ember that breathes.
