What is 59 Cygni

59 Cygni lives in the constellation of the Swan some 1,400 light-years out: a blue Be star spinning so fast that it sometimes wraps itself in a visible disc of cast-off gas. Its spectral variations have been logged without pause since 1916, and in the 1970s it crossed two short shell-star phases —the disc grew opaque and eclipsed the star from within. A slow pulse turned into a real chapter of twentieth-century astronomy.

Where it is and when to see it

59 Cygni lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall

Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.

A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
