Its story

29 Canis Majoris is one of the most extreme creatures of the Greater Dog: a rare blue O-type star, variable in light, sitting nearly 1,900 light-years away. O stars are cosmically brief —they burn so violently they last only a few million years— and very few of them ever reach Flamsteed's catalogue. What glints in its place tonight set out almost two millennia ago, when Rome's last legionaries still lived.
