Its story

6 Lacertae burns blue more than 1,700 light-years away, one of those hot B-type stars that set the tone of the small Lizard, a modern constellation drawn by Hevelius in the seventeenth century. Its surface hovers around twenty thousand degrees and pours out ultraviolet light at a rate that dwarfs any comparison with the Sun. This flicker has been travelling since a time when Earth scarcely suspected the printing press as an invention.
