It could be aliens, experimental U.S. spacecraft or even some other scientific device, but whatever it is, one man captured it.

After a rainstorm, there have been reported sightings of a UFO floating above Houston, Texas. Several images were being shared online over the following days, including two posted by Nathaniel Xavier, aka DJ Nayyz.

One photo shows a ring of lights in a cloudy night sky illuminated by the moon, and another shows similar lights in a dark night sky.

As these photos were shared around the Internet, several local media outlets covered the sighting.

"I think the trick in UFO's is figuring out what else they could be. It's easy to say that could be the aliens," said Dr. Carolyn Sumners, vice president for astronomy at the Houston Museum of Natural Science, to KPRC News. "If it's a real object and it looks like it is. The more people who see it in different directions, the more likely we are to figure out where it is, what it is and see if we can explain it," Sumners said.

Nathaniel Xavier also shared a video on Instagram of the unidentified flying object over Houston.

One expert told the Houston Chronicle what he thought. Fletcher Gray, the volunteer chief investigator for the Texas chapter of the Mutual UFO Network, thought the mysterious circle of lights was a reflection from highway lights because the video was shot through a car window. Gray said, "It's no more than light trapped in the side window." He's basically saying not to call Scully and Mulder just yet. 

In the video, it does look like the lights disappear behind a cloud, which would prove Gray's hypothesis wrong, but that too may be just a trick of the dim light. Whatever the truth may be, these photos and the video have people talking.
