I’m an astronomer at the University of Southampton. I search for black holes at https://black-hole-hunters.org (and so can you!)
I write a weekly astronomy newsletter at https://three-alpha.space

- Wow! Just look at this photo of the Milky Way taken by astronaut Don Pettit on the ISS. Taken with a homemade tracker to counteract the orbital motion. It kind of looks like an aurora, but that's actually just clouds just before dawn. The purple colour comes from nitrogen scattering sunlight. 🧪🔭
- When I first saw Arp 184 I thought it was a small galaxy. It's actually as big as the Milky Way and Andromeda combined. The latest roundup of the week's astronomy news in Three Alpha is up 🧪🔭 three-alpha.space/p/the-strang...
- Quasi-periodic eruptions *might* be due to objects smashing through the accretion disk of a supermassive black hole. New X-ray measurements of the brightest known QPE suggest each collision sends roughly the mass of Jupiter bursting out of the disk at 15% of the speed of light 🧪🔭
