JWST’s early galaxies didn’t break the Universe. They revealed it.
Why does JWST see so many bright, early galaxies?
It's not because cosmology is broken.
The answer has a lot to do with dust, or specifically, the lack of it in the early Universe.

JWST's early galaxies didn't break the Universe. They revealed it.
Originally, the abundance of bright, early galaxies shocked astronomers. After 3 years of JWST, we now know what's really going on.

Indiana University to discontinue more than 100 academic programs, including their PhD in astrophysics, due to low enrollment.
So sad- it’s a great PhD program I know great astronomers have started from 😢

#PPOD: Naturally erupting dust streaks on Mars create structures that look surprisingly like trees near the planet's north pole. These streaks are actually dark basaltic sand pushed to the surface of sand dunes by sun-heated solid carbon dioxide ice, or dry ice, sublimating directly into vapor. 🧪 🔭

M27 imaged over June 22-23, two clear nights in a very cloudy month. The Dumbbell shape (L/R here) is apparent in even in small scopes. With my 15" and a dark sky, I can see the more delicate parts above and below. It's all greenish gray in the eyepiece, of course. 🔭 🧪 #astrophotography
