Jelly fish tendrils pulsing lights in glowing formation on desert horizon.Traveling across desert by car heading to Tonopah NV, witnessed ongoing glowing ember, fire like lights on desert horizon. Continued to see glowing orange pulsating, almost like a continuous slow moving fire on the desert horizon. Had jellyfish blinking pulsating tendrils that cascaded down within glowing light formation. Moved along horizon for almost 1 hour. Both of us over 50 years of age and cannot explain.
