A mysterious string of white lights appears to have caught the eyes of many North Texans Wednesday night.
NBC 5 received numerous emails and pictures showing what appeared to be a long line of lights tracking across the sky around 9 p.m.
From Waxahachie to Argyle and Grapevine to Burleson -- NBC 5 viewers were left perplexed and bemused.
"We were standing outside and looked up in the sky and saw a big light worm in the sky that was perfectly straight," one viewer wrote in a photo submission to iSee@nbcdfw.com. "It appeared and shot across the sky for two minutes and disappeared."
The latest news from around North Texas.
"It's aliens!" one man said as he held his cellphone up to the night sky. "It's either aliens or Elon Musk. Where did it go?" he's heard saying in the video as the lights faded.
He guessed correctly -- Look to Elon Musk for the answer to this mystery.
