Watch the first Ultra Galaxy series, they had to leave the planet because the artificial sun they made was going to meltdown and set the planet ablaze. At some point they show the schematics for the Artificial Sun, explaining the urgency for which they need to leave the planet. Don't forget that the Ultra series is ultimately Science Fiction especially in Ultra Galaxy which has elements of a Space Opera.
