Its story

In Lacerta, the lizard that winds between Cygnus and Andromeda, a blue B-type star burns at about 2160 light-years. Its light set out more than two millennia ago, when Christianity was just beginning to spread across the Mediterranean and the Roman Empire was living its first decades. Tens of thousands of times brighter than the Sun, its bluish-white glow reaches us as a very slow echo of antiquity.
