Summary

On August 15th, 1977, Jerry Ehman was working on a SETI project when he detected a 72-second long blast that crescendo-ed in a noise 30 times louder than the background. Jerry circled the text recording of this noise, commenting "Wow!" next to it in red pen, inadvertently naming the phenomenon. Nothing like it has been recorded since.

Well, hi there. I'm taking a page from Steve's book today and saying, well, hi there.

0:26.2

Hi there. I'm Devon. I'm Joe. I'm Steve. And we three with our powers combined are thinking sideways. Oh, I thought we planned this before. No, I think you need to like coordinate a little bit.

0:42.2

Dang. All right. That was definitely not a page of my book. We actually do need some superhero music for this. You know, I think we do.

0:52.2

Yeah. With the number of mysteries, Joe says Joe is so far. Oh, yeah. I think we claw off like this. Resolving man. Yeah. And tonight we're going to solve another one. We're probably not. Maybe we are. I don't know. I think we will. Okay. No. Joe thinks so. Steve doesn't. I say maybe. Well, at least come up with a plausible theory. Yeah, that's true. A couple probably. I can accept that. Yeah. So I, this is a big one. You guys know it's the wow signal. Is it the wow signal?

1:22.2

Wow. It's the wow. What the actual point. Yes. Wow. I wish you guys could see the crazy faces that we're making. We'll always say that. But I don't want to start out the story of the way everybody else does because I feel like that's super boring. Also, I don't want to. Okay. That's fine. Okay. We're going to be talking about something picked up by a radio observatory or radio telescope called the big ear. It's officially called the Ohio

1:52.2

State University Radio Observatory. It was a, how do you say that? Kraus type? Kraus type, I guess radio telescope located on the grounds of the Perkins Observatory in the Ohio Wesleyan University from 1963 to 1998 at which point it was annex torn down and became a golf course. Yeah. I know. Seriously. Yeah. Seriously. It's a golf course now. Yeah. I think they they developed that that land for like a golf to expand a golf course and also put in some housing.

2:22.2

Yeah. Poor science. Yeah. Poor science. Plenty of other radio telescopes out there. Uh, and I know Joe has a better grasp on science. Oh, yeah. Your science stuff like this. Then I do. I'm going to let him talk about what a Kraus radio telescope has. It has three components, right? Right. Yeah. Yeah. So imagine imagine a flat like sort of almost football field sort of shaped place. And then at one end of this at this thing.

2:52.2

You've got what's called the flat array. The flat rate reflects radio waves that come down from the sky across the field into this vertical parabolic array, which is a curved array. And that reflects the signals back towards the flat array and right in front of the flat array. There are these two things called feeder cones, which which receive the concentrated radio waves into them. And they convert them into electrical energy. So the then this thing is adjusted north and south by moving the flat array up.

3:22.2

And down. So essentially it's changed at the bottom. And then it just like moves up and down. So if you want to look say further south, you move it up for the north, you move it down. And that's how it works. And then in the 80s, you should, yeah, mention that I think that they had changed that. Yeah, they put one of the arrays on tracks. Now they put the feeder cones on tracks. Oh, so they could move east to west and stay with whatever kind of tone. Yeah, if there was just some galaxy, they wanted to observe more.

3:52.2

Closely something like that. They could actually move them slowly side to side and keep it in focus for longer than 72 seconds, because otherwise, yeah, otherwise, we rotated out of because it's the rotation of the earth. Yeah. Yeah. That's how long they could focus on some of, I mean, anything with with any kind of meaningful distance from us. Basically, yeah, it was that the mercy of the of the turning of the earth. Yeah. So this update would have been really, really helpful to have had on August 15th, 1970.

4:22.1

2007, a mere three years before they instituted the track system. So the update you're talking about is where the, was it the ears? Yeah, the feeder cone. The feeder cone is good to move as well. Okay, just make sure I understood which update we were talking about. Yeah, yeah, it would have been really helpful to have a guy who was a member of study. I think is kind of the way you say that.

4:43.5

You're participating in study. Yeah, participate in that you can't really see a member. Yeah, it's an organization. It's just a group of people. Okay.

4:53.8

Mostly volunteer anyway, aren't they? Yeah. Yes. Okay. He recorded what is widely believed to be some of the best proof for intelligent extraterrestrial life out there. Or at least at the very least, one of the things that pretty much everybody agrees. The best explanation for is intelligent extraterrestrial life.

5:13.8

And that's the wow signal, the wow signal. Okay, maybe maybe we'll talk about it. First, some housekeeping. Setty is the search for extraterrestrial intelligence. It's a collective name for a number of activities undertaken to search for intelligent extraterrestrial life.

5:31.5

And it's comprised mostly, I think of scientists, mostly of people who are not like crackpot alien theorists. People who are pretty respected. Yeah, it's not, it's not all winged.

5:43.2

That's some sure there's lots of nuts in there, but most of the, a lot of the people who take part in it are people who do have access to high levels of, you know, like the big year or

5:54.0

Well, you've got to be really qualified to operate or take part and use that equipment. Yeah, we make total. And of course, not everybody is. Some people are just home astronomers and things like that. But generally speaking, if setty says something, they deny a lot of stuff. They say, no, that's definitely not really stuff. So they don't jump right to it every time. I got you. Yeah.

6:13.2

And then we do need to talk a little bit about this thing called cosmic background noise. You guys know what that is, right?

6:19.6

Kind of cosmic background noise is recorded at about 15 megahertz. And it's, it's what you hear when you turn the radio tuner to nothing. It's white noise basically. And what that is is, it's just left over thermal noise from the big bank, which I think is pretty cool.

6:38.7

It's just one of the big bang the other day is a matter of fact, but it's pretty cool. Right, that we can still hear this left over something from it. Yeah, no, the big bang is still with us.

6:49.4

Even today. I have to admit that that is it's what we're supposed to is that a theory or is it accepted as a fact?

6:56.1

Big bang. No, the noise is left over from the big bang. Oh, I think it's I, well, I mean, it's all theories. I mean, even the big bang is only. It's really weird to me. I'm not just
