We are thrilled to say that Brilliant is sponsoring this episode of the Supermassive Podcast.

Now there's no denying that podcasts are a great tool for learning, but so are videos.

You know, I love a video anyway.

Brilliant is an interactive STEM learning platform with a huge range of courses across science,

maths and computer science that get you to learn by doing.

They guide you through these

interactive, engaging hands-on courses so that you really get to grips with the concept.

Yeah, and you really have to see them. The visuals are incredible. I know from my way of learning,

that's just what I need to make sure I really get a grasp on any topic. And they're a great way to just get an overview and learn the basics of lots of different topics. And ultimately, it's fun. Yeah, like I found it quite fun to work through some of the machine learning ones. You know, we use machine learning all the time in astrophysics. And I'm sort of forget the basics sometimes you talk about something so much and you just learn it and you're like, oh, actually, how does this specific bit work? And sometimes it's nice to go back through and remind yourself of that as well. Yeah. And I really need to get stuck in onto that new everyday math course that's gone up this month as well. Yeah. I think we all could do with pushing up on our bad skills, right? And also, if you get stuck, Izzy, brilliant, provide these in-depth explanations to break down the material for you even more. Yeah, I'm probably going to need that. So head to brilliant.org slash supermassive to get started for free and the first 200 subscribers will get 20% off. In the end, it all comes down to one thing and that's, do they have gas left in these galaxies?

Maybe this question from Twitter is just going to cause drama.

Ooh, astrophysics drama.

Sometimes you even see gas and stars moving differently in galaxies.

Hello and welcome to the Supermassive podcast from the Royal Astronomical Society with me,

science analysts, Izzy Clark and astrophysicist Dr. Becky Smith. This month we're continuing

our exploration of galaxies. Last month we covered how they form and this time it's all about

their evolution and their eventual death. So for anyone that didn't hear part one last month,

I mean, where have you been? We're not offended. It's fine. So for anyone that didn't hear part one last month, I mean, where have you been?

We're not offended, it's fine.

So I'll give you my brief guide to building galaxies.

Oh, excited for this.

Okay, number one, it's all about getting gas into one place.

Number two, galaxies come in different shapes and sizes.
