A good premise for a sci-fi series: In the distant future, a large fleet of earth's best and brightest travels the stars while desperately trying to invent Earth's last ditch-effort to save its 12 billion inhabitants from a soon-to-be cataclysmic, near-earth supernovae: FTL travel. After decades of progress finally nears fruition, the fleet permanently loses contact with earth; humanity's home Solar System's remnants lost to the beautiful, nightmare... The fleet of 80,000 now works to save itself, the last of humanity.
Sounds like Battlestar Galactica without the Cylons.
Perhaps the story could have Cylons in it, but here they're allies with the humans, but after the supernova, some religious leader convinces most of them that their god wants them to destroy the humans.
Sounds like a cross over of The Age of Supernova and Tri-body Problem.
In the former Supernova radiation kills all people on earth except kids under 13.
