Blanton explains that astronomy is unusual among sciences because its subfields are tightly interconnected: someone studying stars still needs to track results like Bullet Cluster dark matter observations, since galaxy formation, star formation, and the elements found in stars all link back to each other. He attributes this partly to the field's small size, with only tens of thousands of professional astronomers worldwide, which means most astronomers end up with some working knowledge of the whole field rather than just their niche.

The example prompting this point was a journal club discussion of Bullet Cluster data from James Webb Space Telescope observations overheard at Carnegie.

18:35and and so I like that place where it's a leadership role and you're really it's enabling science, but you're you're sort of close to you know, what's actually happening. >> Right, yeah. I mean, just before we were filming in this room, there was I think a journal club meeting something. >> team. >> Yeah, they were discussing the Bullet Cluster data from the James Webb studio. And I was just eavesdropping and it was such a cool conversation that you know, everybody was just gathered around talking about one paper. So it is an incredible institution. >> Well, the this is amazing thing about astronomy, which which is different than other fields is that well, I don't know how different it is from other fields, but I think it's different is that you know, when you're an astronomer you kind of have to know
19:17all the bits of astronomy. Like they actually all end up being relevant in some way. Uh, so it is relevant to the people who study stars what's happening in the Bullet Cluster. Like that turns out there are enough connections to like how galaxies form and then how stars form and the elements that are in stars that that those things are connected enough that you really have to you know, have some knowledge of what's happening across the field. >> Yeah, so it's not just like dark matter guys or girls looking at the Bullet Cluster. It's like everyone. >> Yeah, well, no, no, I think it's certainly very relevant to to the people
19:58who study uh, galaxies. But then that is connected to the people who study stars, which is connected to the people who study planets and and and it's very hard to you know, you're kind of expected as an astronomer to have some handle on all of that. Uh, and and that I think is and partly it's because it's you know, there's only whatever tens of thousands of of professional astronomers in the world. So it just is a small field. But um, but that I really like about it that you're you you sort of have a connection to almost every astronomer that you meet. >> Right. Yeah, that makes sense. Um, so you've been
