| 0:00.0 | We are absolutely thrilled to say that Brilliant is sponsoring this episode of the Supermassive |
| 0:06.4 | podcast. There's no denying that podcasts are a great tool for learning, but so are videos. |
| 0:11.6 | You know, I love a video. Brilliant is an interactive STEM learning platform that helps you to |
| 0:17.1 | truly understand concepts in maths, science and compute science by guiding you through |
| 0:21.7 | engaging hands-on courses. You have got to see these courses. The visuals are incredible and |
| 0:27.7 | they're a great way to get an overview and learn the basics of lots of different topics. And ultimately, |
| 0:33.1 | it's fun. And this might sound odd, but I genuinely found working through calculations during my |
| 0:39.4 | degree quite relaxing. So I've got my eye on the new everyday math course that's just gone up |
| 0:44.5 | this month. And also, Izzy, if you get stuck, Brilliant provides these in-depth explanations to |
| 0:49.2 | like break down the material for you even more so that it stays fun. Yeah, I'm probably going to need that. |
| 0:56.5 | Head to brilliant.org slash supermassive to get started for free and the first 200 subscribers |
| 1:02.0 | will get 20% off. Although space is very empty, it turns out galaxies aren't actually that far |
| 1:09.7 | apart from each other typically. |
| 1:11.1 | The blueprint is that yes, there's a supermassive black quarter at the centre of every galaxy. If you look at it from one side, it'll look like it's going clockwise. And if you look it from the other, it will be anti-clockwise. Hello, and welcome to the Supermassive podcast from the Royal Astronomical Society. with me, science journalist, Izzy Clark and astrophysicist Dr. Becky Smothers. |
| 1:30.5 | Yeah, this month we're at podcast from the Royal Astronomical Society with me, science journalist Issy Clark and astrophysicist |
| 1:29.3 | Dr Becky Smothers. Yeah, this month we're attempting to tackle the massive subject of galaxies |
| 1:35.8 | also happens to be my favourite subjects as well. It's so convenient, Matt. This topic is actually |
| 1:42.5 | so big that we're going to be doing two episodes all about galaxies. |
| 1:47.0 | Yep. So first up, I chat with Professor Mike Merrifield from the University of Nottingham about how galaxies form. |
| 1:53.6 | And, you know, let's use Becky here. She is our galaxy expert. So Becky will be telling us all about the different shapes and sizes that galaxies come in. |
| 2:02.3 | Plus, Dr. Robert Massey is here, obviously, the deputy director of the Royal Astronomical Society. |
| 2:08.5 | So there are a lot of galaxies, but let's look at our own one. You know, how much do we know about the Milky Way? |
