After a night like Tuesday night, a lot more people will be keeping their eye to the sky.
The internet exploded with pictures, videos and claims of a UFO sighting over the East Valley.
So what was it? A comet? Space junk? Airplanes? Give us your thoughts on our UFO poll.
"With the air traffic patterns in the Valley, what we see are a lot of stacked aircraft that are coming into Sky Harbor," said Dr. Sky, a TV personality and radio host of a talk show that's syndicated across the country and in Canada.
The topic of discussion on his show -- outer space and the universe.
"[Airplanes are] a possibility," he said, adding it doesn't look quite right.
"I'm 41 years old. I've seen a lot of things in the sky," said Christinna Herrmann. "This is nothing I've seen before."
So, was it a UFO?
"Anything that you, or people, saw that we call a UFO is simply accurate," said Dr. Sky, solely because we were not able to identify it.
So, was it aliens?
"Firmly I believe that we already know about alien visitation," Dr. Sky said, citing the Roswell incident from the 1940s. "We're going to continue to search for what [everyone] saw in the skies of Arizona."
