Many Twitter users posted a series of photos about a glowing, circular object in a cloudy sky in Houston, Texas, USA on the evening of August 18.

It makes many people think of lights on an unidentified flying object (UFO) of aliens in fantasy movies, Daily Mail reported.

In a relatively clear picture, it was found that strange objects seemed to fly through the clouds in the sky. The other picture shows it is diverting.

Dr Carolyn Sumners, vice president of the Astronomical Society of the Houston Museum of Natural Science, said: 'This is a unique phenomenon. Many people see strange objects in different directions. Similar events have happened in the past but people cannot find an explanation. It makes people more curious about this phenomenon. '
