What is Omega 1 Cygni

Omega-1 Cygni is a blue variable giant more than nine hundred light-years away, set in one of the wings of the Northern Cross. Its surface exceeds twenty thousand degrees and pours out invisible ultraviolet light, invisible to us but recorded by space telescopes. The visible light now reaching Earth set out before the chronicles of the Cid had even been written.

Where it is and when to see it

Omega 1 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 August: 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.
