A batch of newly released images captured by the James Webb Space Telescope show in remarkable detail 19 spiral galaxies residing relatively near our Milky Way, offering new clues on star formation as well as galactic structure and evolution.
A new set of images captured by the James Webb Space Telescope reveal extraordinary details of 19 spiral galaxies adjacent to our own Milky Way; providing new clues to the composition of stars and the structure and evolution of the Milky Way.
The closest of the 19 galaxies is called NGC5068, about 15 million light years from Earth, and the most distant of them is NGC1365, about 60 million light years from Earth. A light year is the distance light travels in a year, 9.5 trillion km.

“These data are important as they give us a new view on the earliest phase of star formation,” said University of Oxford astronomer Thomas Williams, who led the team’s data processing on the images

The images let scientists for the first time resolve the structure of the clouds of dust and gas from which stars and planets form at a high level of detail in galaxies beyond the Large Magellanic Cloud and Small Magellanic Cloud, two galaxies considered galactic satellites of the sprawling Milky Way.
The images allow scientists to accurately analyze for the first time the architecture of the cosmic clouds of dust and gas that form stars and planets in galaxies beyond the Large and Small Magellanic Clouds. The two clouds are considered satellite galaxies of the vast Milky Way.
