Theoretical physicist Dr. Michio Kaku explains the significance of new images provided by NASA's Webb Space Telescope on 'Sunday Night in America.'have helped researchers examine compact structures of star clusters inside galaxies for the first time.
In a paper published in the journal Monthly Notices of the Royal Astronomical Society last month, the Stockholm University scientists studied the first phase of star formation in distant galaxies. The galaxy clusters they examined were so massive that they bent light rays passing through their center, producing a magnifying glass effect. That means the images of the background galaxies were magnified. That and the resolution of the observatory helped to detect stellar clumps: compact galaxy structures.
Looking at the galaxy cluster SMACS 0723, also known as Webb’s First Deep Field, the astronomers saw even more distant galaxies in its background. The James Webb Space Telescope captured this image of a galaxy cluster . The five zoomed in galaxies are so far away that we observe them as they were when the universe was between one and five billion years old. Today the universe is 13.7 billion years old.
The observations aided in the study of the link between clump formation and evolution and galaxy growth just a few million years
Ooh pretty pictures...let's makeup facts about them.

James Webb Space Telescope Detects Asteroid the Size of Rome’s ColosseumThe object belongs to the poorly known sub-kilometer category of asteroids in the main belt. An asteroid roughly the size of Rome’s Colosseum — between 300 to 650 feet (100 to 200 meters) in length — has been detected by an international team of European astronomers using NASA's James Webb Space Te

James Webb Space Telescope pushed past its limits to observe DART asteroid crashThe grand telescope was not built to track very fast moving objects, but it managed nonetheless. If it's passed it's limits, it wouldn't detect anything. Words matter. If it's passed its limits, it wouldn't detect anything. Words matter.

What's the fairest way to share cosmic views from Hubble and James Webb telescopes?Astronomers are debating how quickly the observations of the Hubble Space Telescope and the James Webb Space Telescope should be made public. Immediately. Unless these agencies don't work foremost for the public? I would think just posting them online publicly would be fairly easy. Maybe I’m missing something Most of the astronomers work for a university or other publicly funded entity. We don’t need to sequester data to protect the egos of these public employees. If there is competition in making discoveries that is a good thing- that is what the taxpayers are paying for.
