Omega Cassiopeiae
Hot blue starWhat is Omega Cassiopeiae
Omega Cassiopeiae burns more than seven hundred light-years away in Cassiopeia, that five-pointed W that stands guard over the north celestial pole without rest. It is a hot blue-white B-type star, a young flame caught in the autumn Milky Way, where open clusters and emission nebulae concentrate. Its sharp glow recalls the defiant pride of the mythological queen who gives the asterism its name.
Where it is and when to see it
Omega Cassiopeiae lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
