Gamma Ara
Hot blue starWhat is Gamma Ara
Gamma Arae burns more than eleven hundred light-years away, a blue B-type supergiant whose surface temperature defies easy comparison. It marks a corner of the southern Altar, that small constellation the ancients tucked beside Scorpius for the sacrifice of myths. Its intense, cold-tinted glow comes from a star living fast and bound to die young, leaving behind the radiance we now see.
Where it is and when to see it
Gamma Ara lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
