Suleiman Baraka in Gaza says this about his work: “I decided to fight the killing of the children by educating the children.... astronomy “is also a window for breathing freedom that we were denied for our whole life". I think this is the reason the world needs it. All of us need his example.

Black dashed is the line of nodes, and lighter purple indicates the part of the orbit that is behind the plane of the sky. Enjoy!

My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: ‘Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’

Come for the fascinating historical poetry about exploding stars, stay for the excellent technical footnote about what different communities are referring to when they talk about “type Iax” supernovae.
