Its story

Antlia is a modern southern constellation, named by Lacaille in honour of the scientific instruments of the eighteenth century. There glows this double system — two yellow-white stars bound by gravity, dancing around one another for countless turns. Its light took about 384 years to reach us: it set out when Galileo first pointed his telescope at the sky and discovered the moons of Jupiter. The very idea of worlds orbiting other worlds was perhaps born then; here, even now, it goes on happening.
