The Cartwheel Galaxy | Space is Weird

Описание: Another #spaceisweird all about how we think the Cartwheel Galaxy formed - similar to Hoag's Object it has a ring but also these strange spokes going from the middle to the ring that we can't quite explain with the usual collision of two galaxies idea...

Oh and somehow we end up talking about Intermedia Mass Black Holes because the Cartwheel galaxy is an excellent place to look for them. I don't mean for all my videos to end up talking about black holes you know but they're JUST. SO. COOL.

My sister made the frame in the background as a present when I passed my PhD. It's not a real certificate. It's a decorative frame in my office which I love. My sister does commissions: https://megansmethurstdesign.wordpres...

We're moving house soon so I'm hoping to get more prints to decorate my new office!
