Q:

There’s supposed to be a type of cloud that is often confused with being a UFO. What kind of cloud is it?

A:

It’s most likely the lenticular cloud, says Brent McRoberts of Texas A&M University. “One reason they may be mistaken for UFOs is their odd shape,” McRoberts explains. “Lenticular clouds are so-called because they often look like a camera lens, many times looking like huge pancakes stacked on top of each other. They are often seen in the western U.S., but have been photographed all over the world, including Spain, Australia and France.”
