Summary

Anthony found an article explaining how astronomers gussy up space photography to convey the scope and beauty of the cosmos, and now he has to break it to Jeff that every image he's ever seen of the galaxy isn't really as rich and vibrant as depicted. Is it important for science to be strictly accurate, or does artistic license play into scientific method? This show is entirely supported by listeners like you! Please visit Patreon to find out how!

Dude I had an enchilada basically the size of my entire head. Yeah. Like that's and it was like four dollars. That's the rule right you're not supposed to eat anything bigger than your own head. Yeah well fuck that rule.

0:35.0

That rules for people with no ambition. This is we have concerns. Hi Jeff canada. Hi Anthony Carvoney. Space Jeff canada. The final frontier. The one in the same. Oh I'm excited already. I love it when we talk space. Yeah space photography specifically is very interesting. You know Hubble photographs. Yeah. Astrophotography and all that stuff is really really awesome. There is a great article in the Mary Sue about it actually. Mm-hmm. About how most of the space images you

1:05.0

see are fake. What? Yeah. No. Come on. That's not true. So well I mean they're fake ish. There we go. Here's the deal. Uh-huh. What color is the sun? Yellow? No. No. The sun is not yellow. The sun is the sun is a star. It is the same color as every other star. So twinkle atmosphere. It's twinkle color. Yeah it's about it's twinkle color. It's like a little twinkle night night. Yeah. It's our atmosphere that makes it look yellow to us. Right.

1:35.0

But because it looks yellow to us when you see a picture that includes the sun. Yes. The astronomer that took the picture. He used the yellow crayon. Well usually use a yellow crayon. So you can look at this picture of all these stars and point to which one is the sun. Wait a minute. Yeah. You're telling me that every picture has been photoshopped. Every. The sun is not as fat and cellulite written as we thought. No the sun. Yeah the sun is actually a.

2:05.0

It's been. Yeah the sun's been slimmed down quite a bit. The sun doesn't have those cheekbones. I didn't. The sun is an impossible ideal. And so I'm glad to realize let's knock the sun down. No. No. I know that I don't have to.

2:20.0

Reelers to be the sun. Yes. Although I would love to be the center of our solar system. And I picture my center of my solar system.

2:27.6

Man. No. So basically every picture you've ever seen of space that is in color. As color as been colorized like a like when they do that to old movies like when they color eyes. It's a wonderful life. Yeah.

2:40.8

They feel incredibly betrayed by this. Do you? Yes. Well, here's a thing that you need to know about space. Here's a thing that we all need to know about space. Number one, most of the. Most of the pictures that are taken of space are taken with either black and white or infrared cameras.

2:55.6

Because they need to take really high resolution photos of something that's extremely far away or something that doesn't give off visible light that we can see. Okay.

3:05.2

So they have to give us a way to see these pictures and be able to differentiate between different things in the pictures. So they gave you a black and white picture like the example they give in the article is.

3:19.6

Famous photo of the eagle nebula like we've all seen the eagle nebula. It's this beautiful colorful. Yeah, gorgeous clouds like floating up in it. The thing is.

3:29.0

If you were to look at that the way they actually took the picture of it. It would be three black and white plates. And.

3:36.6

But is that what you would you would look at it and you would be like, that's that's okay. That's all right. Right.

3:43.0

Because the other thing is they're you know they're taking long exposures they're taking.

3:47.2

But is it are they colorizing it accurately? Are they just colorizing a black and white or infrared photo? There is a shorthand that they that they sort of use. So like in the in the example of the eagle nebula.

3:59.0

You have sulfur and then you have I forget what the other chemical is, but the light given off by the two of them.

4:06.2

Would be too similar to one another they both be reddish.

4:11.0

And you wouldn't be able to see the difference between those beautiful clouds of gas and like those sort of particles on the rim of them.

4:18.6

So what they do is they let the sulfur be red because we naturally associate sulfur with heat and fire.

4:24.4

They turn this other they turn this other chemical blue or green because it's celestial. It's a thing that we associate with space.

4:30.2

Highers right. How does that really make you feel though?
