The Marfa Lights in Western Texas, nine miles east of Marfa, are arguably the most well-known spooklights in the US. Within driving distance of the McDonald Observatory, the Marfa lights have been viewed for over a century. According to a State of Texas brochure, the first recorded sighting was made by a rancher named Robert Ellison in 1883. Apache Indians thought them to be stars that had dropped down to earth. Today they can been seen at night by passersby who park in a pullover spot on Hwy. 90. They are described as changing in color and intensity, and usually move about. Most skeptics believe the Marfa Lights are nothing more than distant auto headlights on another highway, but that doesn't explain the pre-automobile sightings. The town of Marfa even hosts an annual Marfa Lights Festival every September.
