| Description | The Lizard was introduced by Johannes Hevelius in 1687 to fill a small gap of faint stars between the grand constellations of Cygnus and Andromeda. It has no mythological story — Hevelius simply needed a small creature to fit the space. Though inconspicuous, Lacerta sits in a rich region of the Milky Way and contains BL Lacertae — the prototype of an entire class of violently active galactic nuclei called 'blazars,' quasar-like objects whose powerful jets of energy point almost directly toward Earth, first classified as a variable star before their true nature was understood. The brightest star, Alpha Lacertae, is a white A-type star about 102 light-years away. |
