alien night sky

as mentioned alpha centauri skies have similar constellation patterns but additional stars  the most obvious being the sun as chief star in the  combined Perseus and Cassiopeia  constellation "the harper "  nearby is the long  constellation  taking up most of the sky i call the storm sisters  with orion  as the archer  in the jaws of the storm sister Sirius and betelgeuse by their position are seen as a very bright double star   but to alpha centauri  myth are they lovers, brothers or enemies ?

 The sirius  betelgeuse star was once million of years ago  bright Sirius B when it shone as a prehistoric bright star  "Red Sirius"  where as  Red Betelgeuse is only ten million years old  "born after the death" of red Sirius so interesting alien skies  in the distant past  which may have  been celebrated in alien myth
