Marfa, Texas has been enchanted by sightings of mysterious "ghost lights" for over a century. The glowing balls of light of varying sizes show up in the sky seemingly randomly, and behave in ways that no man-made craft or flying animal should - like zipping from one part of the sky to the other, and disappearing and reappearing. You can travel to Marfa to observe the lights yourself, as they are a popular tourist attraction! But could they just be an optical illusion?
US Route 67 is a magical stretch of road, is that is where the famous unexplained lights of Marfa, Texas appear. Although they don't show up all the time, they show up frequently enough to earn a reputation not only in Marfa, but around the world.
Even scientists have tried to explain them. The University of Texas at Dallas studied the Marfa lights in 2004 and was apparently able to prove a strong correlation between highway traffic and the UFO sightings, deducing that the lights were just an optical illusion caused by passing car headlights, a popular theory at the time.
However, many still believe the Marfa Lights have a much more mysterious story than that, considering that their story began in the late 1800s, before car traffic even existed. Some believers have suggested that the Marfa Lights are a mirage created when cold and hot air mix (more specifically a "fata morgana" mirage), while others have suggested these lights could be electrical discharges in the atmosphere.
What do you think of the mysterious Marfa Lights? Could they be an example of weird natural phenomenon, aliens, or just cars headlights? Have you ever seen them in person?
