Incredibly brilliant images have been released this week of the Milky Way and other distant galaxies from the world's largest telescope at the Rubin Observatory in Chile. Derrick Pitts, chief ...

In other words, young galaxies were wild places with lots of action. Another theory is called “progressive thickening.” This idea says all stars form in a thin disc.

More “Relic galaxies, just by chance, did not merge with any other galaxy, remaining more or less intact through time,” said Crescenzo Tortora, a researcher at INAF and first author of a study ...
