Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

If you don't mind looking up Comet 266P and what is its period?

Red Web

Like, how often does that thing fly back around?

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Because if my notes are correct, it might be 40 years.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

It's not too bad.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

That's in a lifetime.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Or it could be 20 or it could be 10, right?

But it's 40 years between them listening to it and 1977.

So most astronomers, I will say, as Christian looks that up, they're largely skeptical of this theory.

Again, to your point, the comet will come back around eventually, hopefully be in a similar spot in the night sky near Sagittarius, and hopefully something more sensitive can listen to it.

And then we can truly say, okay, it doesn't have the signal strength or it does.

Okay, so Christensen's been back since 2017, I think.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

I don't know.

Red Web

Now you're asking a good question.

Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Christian, I wish I knew that when we were researching, because that's something I would love to have looked at.

But ultimately, right, again, a lot of astronomers do doubt this theory.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

There is a way to test it, and it is to listen to that comet when it comes back around.

Red Web

That means that that comet has been around about six times since 1977.

Red Web

So the math works out.

Red Web

But before we move on, I do want to say some other wrinkles.

Red Web

Some have argued that the two comets said to be in the path of Big Year at the time, in 1977, were actually not in the survey area.
