Delta Antliae
Hot blue starWhat is Delta Antliae
Delta Antliae is a hot, young blue-white type-B star some 434 light-years away in the constellation of the Air Pump. Lacaille drew it in the eighteenth century to honour the invention of physicist Robert Boyle —that vacuum pump which transformed experimental chemistry. The constellation is among the dimmest of the southern sky, making Delta one of its few visible points.
Where it is and when to see it
Delta Antliae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is March: 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.
