Its story

An orange K-type star pulses in Cygnus, the swan that glides across the Milky Way with open wings. Its light is not constant: it varies in a slow rhythm, like a cosmic heart breathing in silence. What we see today departed around 445 years ago, when Tycho Brahe, on the island of Hven, was raising the Uraniborg observatory to measure the heavens with a precision unmatched before the telescope.
