Hot blue starWhat is HIP 93855
In Sagittarius, that centaurean archer aiming at the heart of the Milky Way, burns a very hot, blue-tinted star of B type. Its light set out more than eight hundred and forty years ago, deep in the European Middle Ages, when the first sections of the cathedral of Notre-Dame in Paris were being raised. Far hotter and more luminous than the Sun, its violent blue tone is proper to young, powerful stars. It hangs like a forge spark among the densest star fields of the night sky, almost invisible to the naked eye yet burning fiercely.
Where it is and when to see it
HIP 93855 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
