WATCH: Del Rio Residents Share Video of Likely Space Debris Streak Across Night Sky Sunday

On Sunday evening, videos of space phenomenon were posted by Del Rio residents — along with others across Texas and Mexico -- all asking the same question: What is it? While no official word from NASA or SpaceX has been shared with the public, some educated space watchers believe it to be a piece of space hardware breaking apart, likely belonging to Elon Musk’s SpaceX. 

Marilu Vargas of Del Rio witnessed the event with her husband and shared video of the spectacle to social media. “It was truly a sight,” Vargas said to DRNN.
