Iota Aquilae
Hot blue starWhat is Iota Aquilae
In medieval Arabic its old name, Al Thalimain, meant «the two ostriches»: it forms with a neighbouring star a pair at the foot of the celestial Eagle. This is the blue subgiant of the duo — five times the Sun's mass, 850 times its luminosity, with a surface burning at 14,500 degrees. The light reaching us today left around the year 1635, while Galileo was dictating his last observations under house arrest in Arcetri, and has crossed 391 light-years in silence to tint one corner of Aquila blue.
Where it is and when to see it
Iota Aquilae 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.
