Sprites and other atmospheric phenomena mistaken for UFOs

Voice-over: You're listening to the Skeptics' Guide 5x5, five minutes with five skeptics, with Steve, Jay, Rebecca, Bob and Evan.

S: This is the SGU 5x5 this night we're talking about sprites in the atmosphere. Or how natural phenomenon are often confused with UFOs

B: In 1989 scientists discovered classes of electrical discharges high in the atmosphere that were previously unknown. One of these types is called sprite which is an electrical discharge that can take place 35-80 miles above the ground well above conventional lightning bolts which occur 7-10 miles above the ground. And they're quite extraordinary looking and at some point after they're created they can actually travel at I think 10% of the speed of light. And this professor, Professor Collin Price at Tel Aviv University claims that these sprites may in face be the cause for a certain percentage of UFO sightings.

J: And also Bob there's a lot of a lot of phenomenon that happens in the atmosphere that are mistaken for UFOs. One of the examples that we've discussed on the show, actually a couple examples that we've discussed on the show would be umm one of the planets that's in a closer orbit to earth, another example could be umm actually the moon which I was very very surprised a couple of years ago to learn that is often mistaken for some type of space craft

R: I believe you learned that on this very show.

J: I think I did.

R: Yeah people can be really surprised at how things that they assume they would never be fooled by you know when you look at through certain atmospheric conditions or just maybe you're a bit tired, it's late at night. It's amazing exactly how easy it is to fool us with natural phenomenon.

E: that's right and we had President Jimmy Carter on the show two years ago, to discuss his sighting that he had back in 1969 and he, to this very day is convinced that it was not a natural phenomenon that he saw something. Didn't say it was an extraterrestrial or anything like that but... all the indications were that it was the planet Venus. Judging by the time of day and the position of the bright object in the sky. So even someone like an ex-President can be fooled by naturally occurring phenomenon in the sky.

S: But of course if you look at some of the very interesting like these sprite phenomenon which are very cool by the way. I've seen images taken either from satellite or the shuttle at the electric discharges, essentially in the upper atmosphere they're very beautiful, but if you see something like that and you say that's a UFO, it's unknown and start to speculate about alien spacecraft you're going to miss the fact that this actually may be a very fascinating natural phenomenon. Sometimes even though something is natural like electrical discharge in the atmosphere that can also be an extremely fascinating scientific phenomenon. but you may miss that if you're distracted by the pop explanation of UFOs

B: In fact sprites are actually just a piece of the puzzle here there's other atmospheric discharges that were unknown until relatively recently that they all kind of dance across the sky in this unusual way which could be part of the reason why people see these moving light and interpret it as UFOs and they've gave them usual names like elves, goblins and trolls as well and its like Steve said it's an interesting new phenomenon we've only known about it for a couple of decades so it can't hurt to look a little deeper and try to find a natural, naturalistic explanation rather than jumping to you know the "cool" UFO conclusion

s: Of course there's an atmospheric, or alleged atmospheric phenomenon, called ball lightning which is still somewhat controversial and this would be rather than a lighting strike a ball or luminous glowing sphere that can you know be of various reported sizes but it really hasn't been documented that it definitely exists so far but this...

R: Although you can make a similar thing using your microwave but yeah it's never really been observed in nature

(Laughter Steve)

R: I'm serious you can do it in your microwave. Google it. Don't. Don't. Ask your parents first kids.

S: (Laughs) so there we have a genuine scientific controversy masquerading as a sort of scientific pop controversy. The take home message here is if you see something unusual in the sky, natural phenomenon need to be explored thoroughly and there's a lot of interesting stuff happening up there so don't jump past that explanation and leap to the UFO assumption

J: And don't try to simulate things in your microwave.
