Tau Librae
Hot blue starWhat is Tau Librae
Tau Librae burns blue at 367 light-years, set in the scales that part summer from southern autumn. It is a young, hot star — the kind that turns spectroscopic catalogues turquoise and dies within a few hundred million years. Look south on a clear night: what you see is light that left when Galileo had yet to point his telescope at the sky.
Where it is and when to see it
Tau Librae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
