Ask yourself, "Who sees them?" I find it really interesting that professional and amateur astronomers don't report UFO's. Astronomers are experienced, knowledgeable sky observers. They have collectively spent millions of hours staring into the night sky. So why don't we get UFO reports from this group on a regular basis? They take thousands and thousands of photos of the night sky. Why don't all the astronomy magazines have photos of flying saucers?

As an astronomer, I am certain that there are many other civilizations out there on earth-like planets, far, far away. Millions of light years away, unfortunately.

One reason is that astronomers are are more likely to recognize what they are actually seeing, and a UFO quickly becomes an IFO (identified object). An astronomer is more likely to be acquainted with the optical atmospheric phenomena that uninformed observers mistake for flying saucers. For instance, there are frequent sightings of iridium flares (satellites that flare up brightly), regular satellites, sun dogs, moon dogs, parhelia, sun pillars, halos, glories, devil clouds, and St. Elmo's Fire. There are also arcs, patches, and other specific optical effects that can only be seen from an airplane.


Then there are Sprites, dancing lights that have appeared above most thunderstorms throughout history. Lightning from the thunderstorm excites the electric field above, producing a flash of light called a sprite. Sprites can take the form of fast-paced balls of electricity, streaks or tendrils. Fiery balls have been videotaped 35 to 80 miles high, moving up and down at one-tenth the speed of light. Both jetliner pilots and astronauts have previously reported sightings of sprites, along with a different but equally mysterious phenomenon known as blue jets.

Years of searching and millions of dollars spent seeking evidence of life in the universe by looking for some signature of its technology (spanning all wavelengths from radio to visible light) have yet to turn up a single, non-random signal or transmission.

These two photos show red sprites associated with thunderstorms and (below) a halo cloud formation. Flying saucers? I don't think meteorologists would agree.
How many airplane pilots have studied rare atmospheric phenomenon and know what any of this stuff is? Much easier to just report a disc of light that seemed to follow the plane. Remember, a UFO is just that -- an Unidentified Flying Object, not a flying saucer.

We live in an era of Fake News! Ask yourself, "What does the person reporting this sighting have to gain?" The most typical report comes from someone living in a small town in a remote place (often Texas) where there isn't much going on. Typically, several people in town will jump on the UFO bandwagon in hopes of focusing national attention on themselves and their town. The local press is all too happy to get the attention of the national news media, and the national news media is even happier to sell stories. After all, that's what fake news is all about.

Finally, it's completely pointless to attempt to reason or argue with people who believe in flying saucers because, as psychologists tell us, many people believe things for emotional, not intellectual reasons. They simply have a deep-seated need to believe, a need that can never be influenced by logic or reason.

Besides the vast distances between stars, what makes an alien visit improbable? Observations of other star systems has revealed some rather interesting data. Many stars are surrounded by gaseous clouds so dense that anyone on a planet there would never have seen and would not be aware of any other star but their own. Many star systems are binary, consisting of two stars held together by gravitational force. A planet with two suns might never experience enough darkness to see other stars.

Other planets might have no dark night owing to nearby bright stars or planets. There are literally millions of star systems that fall into this category. If the inhabitants of a far off planet were completely unaware of other stars and planets, why would they ever make any attempt at space travel or at attempts to communicate across space?

Of the millions of planets and civilizations that are probably out there, how many have developed an advanced technology without destroying themselves in the process (as we have nearly done)?

Finally, if that one in a billion civilization manages to travel faster than light and discovers our little blue planet, why in the world would they want anything to do with such a primitive, warlike culture?

For all these reasons, including the vast distances and the limitations of traveling near light speed, it seems highly unlikely that we will ever be visited by an alien civilization. Which is sad, because I would be among the first to welcome it!

Personally, I'm still waiting to hear "Klaatu Barata Nikto".

Photos by Pauli Hänninen. These are sun halos or 22 degree halos, which are produced by the ice crystals in cirrostratus clouds. The crystals bend direct sunlight, projecting it elsewhere into the sky, and at a certain angle -22 degrees – a halo can be seen around the sun.

Paul described that night in his village in Finland, “It was cold and very foggy, the temperature was around minus 10 degrees Celsius. When the clouds began to break, there were rainbow colors in the sky and a halo spanning 360 degrees! It was worth taking a picture or two.”

The spots on either side are called sundogs. Sundogs may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low.
