Upsilon Lupi
What is Upsilon Lupi
In the Wolf — the constellation that Greek astronomers pictured as an animal held aloft by the neighbouring Centaur — this A-type white star shines from 407 light-years away. Its light set out at the start of the 17th century, just as Galileo first turned his small telescope toward the moons of Jupiter. The region of sky where it lies also holds the remnant of one of the brightest supernovae ever recorded, SN 1006, witnessed by Chinese and Arab astronomers a thousand years ago.
Where it is and when to see it
Upsilon Lupi 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

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.
