Day Time Ended (1980)

A small family relocates to the Sonoran Desert, to be closer to the grandparents of the family. Though there are news reports of a spectacular triple supernova, and the young granddaughter has seen a glowing alien construction behind the barn, the family is at ease until, one night, a UFO soars over head and appears to land in the nearby hills. Apparently, the triple supernova has opened a rift in space and time.
