Gamma Hydrae
What is Gamma Hydrae
Gamma Hydrae shines as the second beacon of the longest serpent in the sky, a constellation that uncoils across a quarter of the heavens. Its yellow G-type light arrives after a journey of nearly 134 years —a giant long past the stable youth of the Sun, now entering the phase in which its core teaches itself to fuse helium. Astronomers cross it as they trace Hydra from its southern head toward the austral tail.
Where it is and when to see it
Gamma Hydrae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
