At https://phys.org/news/2025-06-largest-universe-revealing-galaxies-early.html … multi national science collaboration project COSMOS-Web Field has produced a map of the universe. It was built from data rendered by the James Webb Space Telescope. It consists of 800,000 galaxies, as recorded by James Webb. It seems to challenge existing notions of the infant universe – and the idea of Big Bang. It over awes the Hubble Ultra Deep Field which only came up with 10,000 galaxies. The James Web data is thought to go back 13.8 billion years ago = 98 per cent of time since Big Bang.
The universe seems to be organised in dense regions amidst voids. Hubble had suggested that early galaxies within 50m million year of Big Bang would be rare. When Big Bang happened things would take time to gravitationally collapse and form and for stars to switch on. The big surprise is that James Webb shows up many more galaxies than expected – and at incredible distances. There are even supermassive black holes that could not be seen with Hubble. It is ground breaking and will take time to appraise. The data is now out there for astronomers around the world to delve into and come up with ideas.

The Rubin Observatory will run the entire visible southern sky every four nights. It will track supernova, asteroids, black holes, as well as the galaxies – in a ten year project. At its heart is a digital camera the size of a small car and weighing over 3 tons. It has 3200 mega-pixels and can spot a golf ball 25 km away.
