Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪 Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students. I wrote this little profile to mark the 100th anniversary of her thesis:

I'm putting the final touches on my second book #EdgeOfSpaceTime and the entire book is an argument for #cosmology and #particlephysics through #poetry. Part of what we can do in #scicomm is make those connections for people. Those connections are powerful & motivating for people, esp in hard times.

Astronomers are closing in on a radically new kind of cosmic map--a map that shows the universe in gravitational waves. The process is hard. This new, preliminary version is uncertain. But we're seeing a fresh view of reality come into focus. 🔭🧪 www.spaceaustralia.com/feature/mapp...

Lots of philosophy of cosmic inflation in the works www.uu.nl/en/research/...
